External Bluetooth Problem

I installed an external usb bluetooth on my macbook pro. No problem! When the computer hibernates the trackpad will not re-start the computer. I need to use the space bar or mouse. The trackpad will not re-start until I open Bluetooth icon in system preferences?

an external usb bluetooth on my macbook pro
I have read that this happens with some external Bluetooth "dongles."
You could search these forums to see if anyone has a workaround.

    My early 2009 Mac Pro does not connect via bluetooth to my sound bar or bluetooth mini speakers. Both my wireless keyboard and mouse have no problems connecting. What do I need to do to connect to external bluetooth devices?

    I would always have a wired keyboard and mouse on hand (need not be expensive ... any cheap wired devices will work).  "Emergency recovery" procedures can activate features in random order, so the opportunity to select a recovery partition may pass before the wireless devices are recognized.
    That will let you select the "turn on Bluetooth" icon.

  • I have got a strange bluetooth problem: Sometimes it's 4.0 LE, sometimes not

    Sorry for my bad english, I will try my best.
    In our house there are my MacBook Pro Mid 2012 and an iMac early 2008. Both with the actual OS X. There are no problems with the iMac.
    I have got problems with bluetooth since updating to yosemite on the MacBook, just like other people here. Nothing helped, no resetting, no deleting any DUN or PAN. I am using now may old usb-keyboard and a trackball mouse with usb cable. The other devices (external bluetooth keyboard from apple and the apple external trackpad) won't connect safely and constantly via bluetooth. The external bluetooth speakers had the same problem. Just every bluetooth thing, iphone 6 plus too.
    I am looking for solutions, but nothing helped me. So I resigned.
    Two days ago I wanted to install the app "near lock" on my iphone. This will unlock the MacBook pro, when I come near it. For this I had to install an app on the mac too, but the app said, that my Macbook aren't have Bluetooth LE - so the app won't installed.
    After 24h later I've tried it again (don't know why...hmmm), and on that day I was able to install it. Everything fine. Suddenly the Macbook had Bluetooth LE.
    Yeah strange enough. Today it happened again. I made two screenshots, from the same MacBook. Only minutes between the shots.
    No Bluetooth LE.
    Surprise.
    I am no technical Pro, so I do not understand this.
    There is a point to state: At the time of the first screenshot my macbook was closed and stood in the twelve book stand with an external monitor. The second screenshot was taken with an open MacBook using the internal keyboard.
    Does this make any sense?
    I would be happy for some help.
    Thanks
    Thomas

    Couple of days ago, this also happened to me, I'm using MacID though. (attached is the dropdown menu for bluetooth on my mac). I'm using a MacBook as well, so obviously the chip is available, I visit to booting in safe mode and restarting solved the problem, hasn't happened again...yet. And, no, bluetooth is supposed to work in clamshell mode. Just so you(and everyone else) know, you're not the only one.

  • Bluetooth problem Yosemite

    I bought a new iMac 21,5 with wireless keyboard and the Magic Mouse.
    I've been using it for about two weeks now and everything was working fine, until i installed the new OSX Yosemite when it released.
    Now, about 10x an hour the computer loses the bluetooth connection with the keyboard.
    This is very annoying, since i use it for 3D drawing, and everytime it loses connection, i have to fill in the numbers again.
    I've read on the internet that a lot of people share these problems.
    Is Apple coming with a solution or update? Or can i fix this myself?
    Read something about resetting RAM etc as well. But since my computer is new, I dont think that'll do it.
    Thank you very much.

    I had the bluetooth problem where my MacBook Pro wouldn't reconnect to my external bluetooth keyboard after the initial connect when I upgraded to Yosemite. I found the solution in another thread from nashntk:  "everything were solved by resetting SMC Intel-based Macs: Resetting the System Management Controller (SMC)."
    So far, the SMC reset fixed all of my bluetooth issues after the Yosemite upgrade. And it seems to be an ongoing solution as one reset has allowed me to disconnect and reconnect again multiple times.

  • External bluetooth speaker volume to low

    Hello,
    I have an external bluetooth speaker from jawbone called jambox. From the start on I had the normal speaker volume like I also stil have it if I connected the bluetooth speaker with my iPod touch. But some day ago, the volume from my whole Mac (not just from iTunes) dropped through my Jawbone. It is not just about 40% of that, what I know of, that the Jawbone Jambox is able to bring.
    This problem exists through all audio / video programs on my Macbook Pro. So like in iTunes, also in VLC or MplayerX. Everywhere. The software sound of MacOS Lion is on maximum. Also the sound control of the jambox itself is reached. It seems like there is a protection against to high volume anywhere turned on which just do not allow me to turn up the volume beyond a specifc point of db.
    But, I can only repeat: The speaker is in a good shape. I am able to play music much more louder with my iPod paired. But just not with my macbook. I am looking for a "hidden" option to disable the maximum volume limitation of my Mac to the speaker.
    Would be happy if anyone know a solution for that issue...

    Same issue
    Works fine on my HTC thunderbolt, Even works fine on my brothers Mac (same year and OS build).
    My audio used to work fine through my bluetooth adapters but now the audio is way lower than it should be. This is a recent problem, it worked fine before. I believe an update may have cuased this, then again my brothers mac is working just fine even after the update. I even tried switching the bluetooth adapter and it still has the problem so I know its my Mac.
    Please fix this issue...
    Me and my brother Both have 2011 Macbook Pros, running 10.7.4 and the adapters are Blackberry adapters used to receive the audio from my mac and play through my home entertainment system via aux jack from the bluetooth adapter.

  • Mini Bluetooth Problems - Dongle instead?

    Given that the new Mini has old Mini Bluetooth problems (and no solution in sight from any Apple folks), anyone have luck or solutions for disabling the internal 'radio' and using an external BT Dongle (say, D-Link)? When I turn BT off, and plug the dongle in, nothing happens - even after a reboot.

    Well, - I'm having the same problem as described in the first post. The N97 mini connects flawlessly with some PCs, headsets, and handsfree car systems.
    I disagree with the purpose of remote SIM mode as before mentioned. Remote SIM access is to support the rSAP (remote SIM access profile) installed in some premium handsfree systems (like in my Skoda Superb) and basically lets the handsfree system 'steal' your SIM, including PIN etc. over BT for use with its own built in phone.
    But in my new Mazda MX-5 I am having trouble to place calls with the handsfree car system. It is not a rSAP capable system and I have tried with and without rSAP in the N97 mini enabled, to no avail.
    The N97 mini pairs fine and I can receive incoming calls. Also, I can place calls from the device itself, but when I try to place a call over the car's handsfree system it basically freezes for a few minutes before the car system throws an error. During these minutes I can see on the car display that it looses connection to the phone, albeit the N97 mini still shows connected state. Once these 1 or 2 minutes have passed, the phone shows disconnected, and then reconnects immediately. By experimenting a bit, I found that when I change the BT visibility, from not visible to visible or vice versa, during those minutes, the phone catches up with the number and dials.
    And yes, my N97 mini is on the latest FW (12.0.110).
    It's a pity that this problem is obviously already so old, that I have little hope Nokia is going to fix it. My old 6600i slide, and my wifes 6131 are working like a charm, unfortunately I need the N97 mini to work for other reasons ...
    Despite I don't know if the N8 would work, it's not an option since it's not supported by PC Suite anymore, thus doesn't synchronize with Lotus Notes, which is what I need at work.
    Any help would be greatly appreciated ... thanks

  • How do I connect an external bluetooth keyboard to my stream 7

    I purchased a stream 7 a couple of months ago.  connected an external bluetooth keyboard to it.  now the external keyboard will not connect.  When I search for bluetooth devices, nothing shows up.  sometimes the stream 7 will pick up my fire on the other side of the house but not the keyboard that is right beside it.  Is there a setting that I have wrong?

    Hello kutou, There could be one of several things wrong for the bluetooth keyboard to not be recognized.It could be the bluetooth drivers need reinstalling or there could be something wrong with the keyboard itself.You did check for bad batteries I assume? Here is a link to some troubleshooting info from Microsoft that you could try first.Troubleshoot problems with Bluetooth enabled devices If that does not work, here is a video on how to uninstall and reinstall the bluetooth driver.▶ How To Fix Bluetooth Not Working In Windows 8.1 - YouTube Here is the download for the bluetooth driver if needed.Its the same for the Stream 7 5701 and 5709 models.http://ftp.hp.com/pub/softpaq/sp70001-70500/sp70340.exe Let me know how it turns out.

  • Non support of external Bluetooth GPS--- WHY???

    I have an iPad2 wifi I want to use as a moving map system for flying.  Apple does not support external Bluetooth GPS units, .... WHY????
    I don't want to have to buy another BT GPS, as I already have 4 that SHOULD work.  Short of Hacking the iPad, there is only one BT GPS that works.
    I'm dissapointed, and may have to return this iPad if I can't get it to work with what I already have.
    Any ideas??
    Thanks.
    Dave

    Chris,  None of my BT GPS units below will link to the iPad.  I have had no problems at all with linking them to any other PDA, Laptop, or Computer that I've tried.  (OK, all PC's) 
    The GNS 5870 will connect to Apple only.
    The Dual XGPS 150 has a switch to change from Apple to all others.
    I don't want to have to buy another BT GPS just for this iPad.
    1.  Holux GPSlim 236B

    3.  Socket BTGPS
    4.  BTGPS (I think mod. 238)

  • Anyone not having bluetooth problems - Yoga 13

    Hi
     
    Just want to check - is there anyone who is not having any bluetooth problems.
     
    If yes can you please post here your machine configuration and devices you are using with bluetooth
     
    Ken

    There might be a couple of things to try. You could borrow an external keyboard to use for a while--or even buy a cheap one used, and see if you still have problems or not. If you don't, there's likely a problem with the MBP keyboard itself.
    Also, if you have access to an Apple Store, you might be able to make an appointment with the genius bar and get a definite diagnosis. It may be possible to arrange to get in a replacement keyboard at the Apple Store and have them fix it while you wait. Don't know for sure if that would be possible, but it's worth asking. Same with an Apple authorized repair shop--it might be possible to get it fixed without having to send it off.
    Good luck!

  • Can I use an external bluetooth adaptor instead of the internal one?

    HI Folks,
    I need some better range for some bluetooth to serial adaptors so I purchased a class 2 (or was it class 1? memory fading but the higher output one) USB bluetooth dongle which advertised as being Mac compatible. Unfortunately when I plug that into my mini (previous generation core 2 duo mini) I can't see that I can disable the internal device. It shows up on the USB bus but as far as I can tell the system is continuing to use the internal device.
    Is there a way to tell it to use the external device? Can I crack the case and remove the internal module? I know the airport module is a separate card I can unplug but can I do the same to the bluetooth?
    Thanks for any suggestions!
    James

    heh, so I should have just tried it again. Last time I did this was a couple of OS versions ago though I have no way to know if that is what did it. Upon plugging back in the class 1 external interface is now appears that my machine is properly using BOTH interfaces. IN the discover new devices screen it now sees itself as an option which it never did before, and shortly thereafter the previously out of range devices popped up as well. So in order to use an external bluetooth adaptor it doesn't appear you have to do anything other than plug it in. It did not do this the last time I tried though.
    In any case, thanks!

  • Possibly mundane Mini-DVI to VGA into an external monitor problem

    Hi,
    I've had a look over the interwebs regarding my problem and it seems as if it's not unusual to have external monitor problems but I'm not sure if mine is slightly different:
    I had a perfectly working set up with my new Macbook (the white one, '06 model I believe), that was connected to my Hanns-G HU196D monitor via a mini-DVI to VGA adapter, no problems whatsoever. But for a couple of weeks now my Macbook just flickers a light blue colour, with nothing at all on the monitor, and my macbook is unusable until I remove the adapter. I've read about updating firmware but I can't see my desktop once the macbook is connected to the monitor so it's not possible to configure anything. I've read somewhere that my external monitor isn't compatible with this set up, but it was until a couple of weeks ago!
    My Macbook's 4 months old now and since then I've bought a new mini-dvi to vga adapter and a new VGA cable, no connections seem loose on either mini-dvi port or my monitor's vga port.
    Thanks if you can help!
    Jack

    You will need to use a mini Dvi-dvi and a dvi-svideo/rca adapter.
    Joy joy hallelujah.
    Pardon the sarcasm...I just wasted 3 hours of my life trying to sort the issue out.
    Heard a KWORLD PlusTV PCTOTV Converter SA235 USB 2.0 Interface would sort the issue out for under 40$ but it's not Mac.
    Hope that helps.

  • How to Solve Wi-Fi or Bluetooth Problems on your iOS Device?

    Do you have any problem with Wi-Fi and Bluetooth on your iOS Device? Please read these steps carefully and follow it!
    These Steps that I am sharing are TESTED by 10 iOS users what had problems with Wi-Fi or Bluetooth or both and was successful
    - Please note that Resetting/Factory Resetting/Hard Resetting or Recovering or un-jailbreaking your device will not work at all -
    To Solve Wi-Fi Problems Follow these steps (But before doing anything please restart your iOS Device and see if you still have network problems):
    Step 1 Go to Settings > General > Reset > Rest Network Settings and Reset your Network Settings and wait until your device re-boots
    Step 2 Go to Settings > Wi-Fi and see if you can connect to your Wi-Fi If you can't then go to next step
    Step 3 Go to Settings > Airplane Mode and turn on Airplane Mode and shut down your device. Go to your network provider and ask to restart the Modem or do it your self (Just unplug power cord and plug it back in) You have to wait 30 seconds.
    Step 4 Boot your device and go to Settings > Airplane Mode and this time turn if off and go to Wi-Fi and see if you can connect it again. If you can't then go to next step - Note: If you are going on to Step 5 it means that your device is experiencing Critical System Error that cannot be fixed easily -
    Step 5 Go your laptop/desktop and open your browser then type this on the webpage search bar 192.168.0.1 and click enter. If it doesn't work then go and ask your network provider for an address for your modem/internet settings.
    Step 6 Change your modem/internet settings to no password and make it "available/visible for everyone" and go to your iOS device and got to Settings > Wi-Fi and see if it works this time. If it still doesn't work go to next step - Note: If you are going on to the next step it means you are experiencing Critical System Error that had been cause by glitch/bug -
    Step 7 Connect your iOS Device to iTunes on your laptop/desktop and update your iOS version -Note: this process if basically re-installing your operating system- If you can't update if because the new update if not available you have to wait for next update unfortunately
    Step 8 After updating your iOS Device Go to Settings > Wi-Fi and see if it connects to your Wi-Fi. It normally fixes the problem but if it still doesn't, it means your device is experiencing hardware problem. Visit your local Apple Retail Store or reseller and ask them for complimentary/device-exchange/warranty help or go to Apple website for online support: www.apple.com/support/ for better support.
    To Solve Bluetooth Problem all you need to do is resetting (not factory resetting) your device and see if it works, if it doesn't you will need to update your iOS or Google for more technical troubleshooting because it could be your pairing device's problem. Visit www.apple.com/support/ for better support.
    If anyone of you had these experiences and was successful troubleshooting please do share your experience. I will also be avaliable to answer your questions if you have one! Please do share your openions about my post if you have one

    If you don't mind, would you do that for me please?

  • Bluetooth problems all around - Modem in the first row.

    Hi there,
    I've got a really annoying problem with the Bluetooth Setup of my Mac. Like you can see in my system description, I use Mac OS X 10.5.6. For a long time I used my old mobile via Bluetooth and GPRS as a Modem. Now it was time for a change. I bought a new mobile which supports 3G (Nokia 5800 Xpress Music).
    I used the Bluetooth Wizard and told him to use all possible bluetooth functions of my device. I looked in the internet for the right configuration (APN, CID,...) and choosed to use the Nokia GPRS/3G Modem script which is preinstalled in Mac OS X (I also tried another one from www.taniwha.org.uk, it didn't work either).
    The very strange thing is, the first connection worked without any problem, but after disconnecting and reconnecting it didn't work anymore. Instead I've got a message that the RFCOMM-Channel can't be opened.
    I tried to fix the problem myself by searching wrong settings in some plists, but although I restored the original settings after recognizing that my changes didn't work, I've got a new problem.
    Now the status symbol of the bluetooth modem always shows up that no modem configuration could be found, although I can still try to connect via Network -> Bluetooth. Of course it doesn't work this way too.
    Sometimes the bluetooth modem works once after a reboot ( not after every reboot ). But only once!
    File Transfer always works! The Nokia Multimedia Transfer also always works.
    I definitely need advice of some of you, experts.
    I'd love to hear from you!

    Hi,
    sorry, but the problem isn't solved yet. I tried different things but nothing helped:
    I backuped and deleted the following Files:
    /Library/Preferences/SystemConfiguration/Preferences.plist
    /Library/Preferences/com.apple.Bluetooth.plist
    /Users/benutzername/Library/Preferences/ByHost/com.apple.BluetoothHASH.plist
    But it didn't help. In fact it made things worse. Therefore I restored the backuped files.
    I deleted all bluetooth devices and installed just my new phone a bunch of times. - No change at all.
    I used FSEventer to control the Filesystem Access. That leaded me only to the files mentioned above.
    In the log-file:
    /private/var/log/ppp.log
    is the following error message logged:
    Failed to open /dev/cu.Bluetooth-Modem: Resource busy
    Up until now, I don't understand why this resource is busy.
    I figured out, that the modem works using a USB-connection. That isn't a satisfying solution but it works for now.
    Nevertheless I am still really interested in resolving the Bluetooth problem.
