IPhone 5 Bluetooth Smart - Fitness apps disconnect sensor automatically

I am using ALATECH cycling speed and cadence sensor, similar to Wahoo, Runtastic product.
For many times that I have tested with several app, ie runtastic, mapmyride, strava, to name a few, the sensor will be disconnected after a while, say probably a 6KM ride.
Can't say is the sensor problem, because after restarted the iPhone 5, the sensor connect back again.
Can't say the apps either because it happens to all the apps I am testing.
So I guess it must be the iPhone 5. Anyone has s

If the sensor keeps disconnecting, it could well be a sensor problem. I've used a Wahoo sensor, Polar sensor, Pear sensor with my iPhone 5 and 5S with no problems. I'd start by contacting the manufacturer of the device or seeing if they have any support forums.
Best of luck.

IPHONE 3GS - Nike Fit APP froze phone

I have an iphone 3gs. I opened the nike fit app and it froze the phone - i completed a factory reset and now it will not come off the black screen with the apple on. I have done everything - it seams to have just completely died?

Transfer purchases transfers purchases from the iphone to the computer, NOT the other way around.
You need to sync the app as you do everything else. Go to the apps tab and select it, then sync.

Have you checked on other screens to see if it is there?

IPhone remote app disconnects, iPad does not

Environment Info
Windows 7 64-bit
iTunes 12.1.2.27
Latest update on iPhone and iPad
Remote app
Single network, single wireless access point
I have home sharing turned on in iTunes, I play my music throughout my entire house from my PC and control via the remote app. I migrated my iTunes library to another PC and I am now having remote issues. Now the remote app frequently disconnects after my phone locks and the only way I can get it to reconnect is by turning off home sharing and back on again. I've made sure to turn off sharing on the other PC, and uninstalled iTunes.
After some testing it seems that the disconnect does not happen on my iPad, only my iPhone. I've gone through the home sharing troubleshooting page, obviously my home sharing is working, just not all the time. I have to turn it off and on again to kick in the head. I've also disabled IPv6 as well.

Hmmm interesting, I'll have to see if I can change that option. This isn't my setup, its a friends.
I may have been running into a different issue. I got down and dirty and pulled out Wireshark to see what was happening and found some interesting things. My friend has two wireless access points and I was wondering if we were running into an issue with WiFi going into sleep mode on the phone and the remote app timeout while waiting for the wireless connection.
I disabled the second AP and things seemed to work better, but the remote would still fail to connect once in a while. Thats when I saw that the remote app makes a DNS SRV request looking for a PC on the network that has iTunes, so I looked at the DNS settings on the iPhone and noticed that DNS was pointing to two ISP DNS servers first, then the internal router DNS. I swapped the internal DNS first, and ISP DNS second, renewed the DHCP lease on the phone and things are working great now.
Either way it seems like the remote app is a bit tempermental with its timeout, it seems like it either gets stuck looking while it waits for WiFi or a DNS response. But at least its working much better now, sorry for the long post.

What's the best Bluetooth file sharing app for iPhone

I'm trying to find a good BT file sharing app for an iPhone 5. I've noticed that the iPhone 5 won't even detect devices such as other phones or computers with BT but seems to have no issue with BT accessories such as satnav. My iPod touch has no problem detecting any BT device which seems odd.
So, is there a good BT file sharing app availble for an iPhone 5?

You won't find any Bluetooth File Sharing app that will work with non-iOS devices. That is something iOS simply does not support.

3GS doesn't fit into iPhone Bluetooth Headset cradle?

Just got my first iPhone, the 3GS. However, I already own the iPhone Bluetooth headset, which comes with a cradle that it supposed to accommodate the bluetooth and the iPhone. Since the new 3GS supposedly has the same dimensions as previous phones, it should fit, right?
I tried putting the 3GS into the cradle and the latter was a tiny bit too small. The phone almost fit in the port but didn't, and I didn't want to force it. Anyone know if it's supposed to fit?

It is not supposed to fit, and murray65 is correct - Apple never made a dual dock for the iPhone 3G, and in fact, early this year they discontinued the Apple Bluetooth Headset. You can either just use the travel cable to charge both devices, or you can use a Dremel (or carton knife, etc.) to widen the opening in the dock for the iPhone to accommodate the slightly larger and more rounded iPhone 3GS. See the last few posts in this thread for some links to pics of the process.

Thank you for the answers so far, but I'll make one correction: I said earlier that the Boston Globe website, boston.com, does not have a mobile site, and I would need to visit their regular website on my iPhone. Actually, I just found out that boston.com has a mobile site, so I'd obviously use that instead of the regular site. By doing that, I'd save a ton of data (I think). Does that change your answers?

Using BT Smart Talk App on iPhone 4 - Can make call but receiver can't hear me

Switched to BT and the BT Smart Talk App appealed, which I've downloaded onro my iPhone 4.
Been through registration process with BT for Smart Talk App (after downloading IOS7.0) which went well.
However I've tried to make several calls and no-one can hear me.
The phones itself works perfectly in usual phone mode.
I have, of course, tried to resolve this with BT but got nowhere.
In fact I was given several possible reasons all of which I think they made up!
They are now due to call me next week.
I've heard of several strange solutions (one using a piece of cardboard being one!!) but I'm guessing I'm not the only one facing this challenge.

Go to settings :privacy:microphone: then turn on access to microphone ,that should cure your problem

Hi i received the nano 7th gen for Christmas and I only seem to get 5 hours of battery life. I use the Bluetooth and Nike app so I expect more drain on the battery. But I got more time out of running with my iPhone. Does this sound normal? I thought I should get close to 30 hrs of just play time alone.
ALso, my wife got me the Belkin armband to run with the nano but I sweat through the band resulting in the back of the iPod to get wet. Surely this is not good. Anyone have a recommendation for an armband that keeps moisture away from the pod?

iPod Nano are small and they don't use Wi-Fi access so you get less power time on a Nano. As for iPhone, since you got apps, Wi-Fi + 3G access, and everything else, they give you more time so you can keep using. Nanos are ment to listen to music, listen to radio, view your photos, watch videos (without Wi-Fi) and since you got BlueTooth on the nano, it counts as wireless access so it drains your battery faster.

TS3899 iPhone 5s Mail app shut down automatically when try to send email

I just set up new iPhone 5s two days ago from iPhone 5.
Everything works fine except Mail app.
Due to Mail app, I had to set up new configuation instead of back up from old iPhone 5.
Mail app works fine 1 day, but after the day after, the mail app shut down automatically when try to send email.
Just one specific email account has problem. It worked fine on iPhone 5. Same setting on Pop and SMTP. Exactly same~~
- I did try to reset iPhone 5s pressing home button and sleep button for 10 second. It did not work
- I did try to reset all information and install iPhone 5s and the problem still exists.
- I did try to delete specific email account and re-make it, but it did not work
Funny thing is that if Lanuague is English, then sending email is working. Absolutely no problem.
However, if Language setting is Korean, then Mail App shut down automatically.
I'm heavy email maker and if it is very annoying.
Does anyone have same issue like this?
I believed it is iOS7 bug?
Can anyone help me on this???

Am having similar problems with a new iPad Air. It will recieve email in Mail as directd from my domain email account. It will not send, advising server does not recognise account. I have checked and re checked settings.
My computer and old iPad work perfectly. Any ideas would be really appreciated.
By the way sending email directly from the domain email account works perfectly but I prefer using Mail.

Thank u

Hi softwater,
Thank you for the suggestion. I haven't looked into Carbon Copy Cloner previously, I'll check it out.
I'll see what I can do about getting to a store. I've only just had the MBP13 get a logic board replacement, for which it had to be in store for a week, so I'll have to make plans to move data around so I can keep working while it's out of action.
I won't be able to take it to a store for at least another week, so if anyone else has an (unlikely) solution in the meantime I'd be very appreciative!
Thanks

Mac Mini can't identify BlueTooth smart devices

I have a Kurt Kinetic InRide Watt meter and corresponding Heart Rate Monitor (Wahoo Fitness TICKR) that our Late 2014 Mac Mini (2.6 ghz i5 OS X 10.10.2) can't identify. The devices pair fine with my iPhone 5s and iPad Air 2 so I'm sure it doesn't have to do with the devices. But when I turn off the bluetooth for these other Apple Products and open Bluetooth preferences on the Mac Mini, the computer can't find the bluetooth smart devices.

Reading this
https://kurtkinetic.com/products/kinetic-inride-pod/
which includes
The system uses the new Bluetooth Smart™ communication protocol found in Apple devices including the: iPhone 4s and 5-series and 6 and the iPad 3, 4 and Mini and iPod Touch 5th generation to wirelessly pair a heart rate monitor and power sensor pod with the new Kinetic inRide iPhone App* to measure power with any Kinetic fluid trainer.

It appears to not be compatible with computers.

Bluetooth smart

Hi, I read today that the iPhone 4S has a new app and it's called "bluetooth smart". It will inform you about new incoming mails, phones and some things more. I'm especially interessted in getting more information about the point "checking the blood sugar level" because I'm a diabetic and it would be great if I don't have to ***** seven times a day to check my blood sugar level.
I know it needs a chip that the information can be sent to the iPhone. But is it still available? Does it really work? Where do I get more information? I hope somebody has more information for me? Thanks a lot.

Hey there, Nadin77. Not sure if such an app exists, but the iPhone 4S is equipped with Bluetooth 4.0, a relatively new low energy protocol, which has recently been named "Bluetooth Smart" by the Bluetooth SIG. By adding this technology to their iPhone, Apple really has ushered in a new spectrum of interesing new connectivity possibilities, many of them health care and fitness-relates, since low energy (or Bluetooth Smart) technology seems to be easily adapted to sensor technology.
I did a quick look to see what's on the horizon for glucose diagnosics for the iPhone, and found this...

Take a look - seems like a good site for diabetes information.

Lightroom CC syncing and deleting across Mac, iPhone, and iPad Lightroom apps

I have searched for nearly an hour for some answers and find the Lightroom support sections massively confusing, even contradictory (example here: Adobe Lightroom on mobile FAQ In one answer it says that "Lightroom on mobile syncs original JPEG and PNG files that originate from your mobile device in the Creative Cloud" and in another question right below it says "Since Lightroom on mobile does not store your original image files, but instead syncs Smart Previews"). I need some basic questions answered around how these various platforms inter-operate [BTW, I am running latest OS and App versions across the board]:
1) Do images taken with my iPhone automatically get uploaded to Creative Cloud (CC) or not and are they at full resolution? [Seems like they sync once I open the app, but not sure of resolution. Would be good to know what is supposed to trigger the syncing, e.g., opening the app, taking the picture, etc.]
2) Once an image is uploaded to CC from the phone, and I can see it in Lightroom desktop, are changes made to the image from either device's version of Lightroom automatically synced, i.e., I will see the changes made from any device on any other device the next time I log into CC from that device? [It seems like this is the way it works, but again not sure]
3) Assuming the whole image is uploaded intact from the phone to the CC, if I delete the image in the Apple Photos app, will that in any way affect the CC cloud image? I am not deleting it from within any Lightroom app at this point -- just the native IOS app. [Does not appear to be in any way connected -- which is both good and bad -- must delete in multiple places now]
4) If I delete the photo in the CC from the desktop, does it delete the native photo on the phone as well, or do I need to delete it in both places to get rid of it entirely? [It would seem that when I delete the photo from the Lightroom iPhone app, after it has been synced, it does not delete it from the Lightroom desktop version -- I still see it there]
5) I assume videos taken with the phone are not uploaded -- is that right? [They are not loaded to the CC as best as I can tell]
6) Do the iPhone photos that get uploaded to CC end up only as preview-like images on the desktop version of Lightroom, or is the entire original resolution image downloaded to the desktop? If it is not downloaded, how do I export a full resolution, modified image from Lightroom desktop (or from the iPhone for that matter)?
7) I am not seeing any of the 25,000+ photos stored on my desktop version of Lightroom getting synced to the cloud -- isn't supposed to sync a preview image, and if so, how do I enable that? What happens to changes to that preview image made from the phone -- do they get made back on the desktop version of the image through Lightroom?
Thanks for the help. I wish Adobe made this clearer up front so as to avoid any accidental deletions and to ensure the products are interoperating the way they should.

Let me try to answer your questions.
1)
collections created within the Lr Mobile app will be automatically synced to the back-end. You can add photos manually from your camera roll or enable a collection for "Auto Add". With that all future camera shots will be automatically imported to Lr Mobile and synced
2)
correct. changes will be synced from Lr Mobile to Lr Desktop - back&forth
3) local camera roll deletion is not connected to the Cloud back-end. But be carefull that the import/sync is finished before you trigger that.
4)
as answerd before. the cloud back-end is not connected to the device camera roll
5)
video is not supported yet
7)
original resolution images will be downloaded to Lr Desktop. Preview images will be shown in the Lr Web view Adobe Lightroom
8)
when you create a collection within Lr Desktop and add your photos you would like to sync, then you can enable this collection for sync. As soon your are signed-in and start the sync (via the top left activity panel) you will notice a little checkbox beside the collection. When you check this sync start to run. Lr Deskop generates smart previews and uploads these to the back-end (plus thumbnail previews + meta-data). When you open up Lr Mobile app and you would like to make an edit, the Lr Mobile app loads the smart preview form the back-end and syncs back the meta-data or edit setting.
Hope that helps you to start.

I have an iphone 4S with broken wifi (!) and I need to sync my contacts before I set up my new iphone 6. I thought contacts synced automatically with itunes but seems not. I've found my Apple address book but contacts are outdated. What to do? Help!

I have an iphone 4S with broken wif i :-( and I need to sync my contacts before I set up my new iphone 6. I thought contacts synced automatically with itunes but seems not. I've found my Apple address book but contacts are outdated. What to do? Help!

If your Bluetooth is working, you may be able to tether your phone to another device, and backup that way. Either via iCloud or one of many Apps that send yourself a VCF file containing your contacts.
You may have to update to a later IOS via USB and iTunes, not sure if IOS 6 has Bluetooth Tethering.
I would have thought you could also switch off cloud sync'ing for your contacts, this should ask a question if you want to keep the contacts on your phone. An iTunes Backup and then Restore to your new iPhone should restore the local contacts. Then sync these back to the iCloud.
Hope this helps.

How do i transfer a video back onto my iPhone in the Photo app where it originally was and can be shared from (NOT the video app)

I have a video that i originally took using my iphone but then transfered to my PC. I want to put it back onto my iPhone in the photo app (NOT video app) so i can share it straight from my phone.
Since one of the iphone updates enabled the volume button as a camera shutter button and i was shooting the video one handed, i held the camera with the volume buttons on top. Unfortunatly, the phone still saves it in such a way that only the iphone and itunes recognize the proper orientation intended and when it's opened with any other device or program, it automatically makes the part of the video that's against the smooth side of the phone always the top side (regardless of if that makes the video sideways or upside down). I was able to get the video back onto my phone as a "video" where it shows up in the video app as a "movie" and there are no options to share via text, email, youtube (which were options when the video was still in the photo app). I need to be able to share the video with family

Have you transferred photos from your computer to your iPhone which is selected under the Photos tab for your iPhone sync preferences with iTunes?
If so, you can place this video in the folder of photos on your computer that is selected to be transferred to your iPhone via the iTunes sync process. Under the Photos tab for your iPhone sync preferences with iTunes, select Include Videos.
