A bluetooth serial failure

I have the following message on my Mac which is repeated five time and will not clear " Failed to open an RFCOMM serial channel. Check if authentication needs to be enabled in your device. All I can see when checking software is the Track pad has a channel that does need authentication. I will say the pad has been accepted by my system and is working. My question is how do I enable if required and will this delete the error message(s)

This a fault on my computer . Yesterday evening my computer was flooded with e mails covering all queries because as I was advised a worm had attacked ny system I thank the person very much who assisted me in stopping the deluge of messages. My original question is still outstanding I bEing new to the discussion system may have made some errors but all I can say is it is problem on my Mac thank you all

I have suddenly started getting "A Bluetooth Serial Failure Has Occurred" message suggesting the computer failed to open an RFCOMM serial channel: what do I do?

I have suddenly started getting "A Bluetooth Serial Failure Has Occurred" message suggesting the computer failed to open an RFCOMM serial channel: what do I do? This "opens" multiple times: three or four 'tiles.' It seems like the computer is looking for something, but can't find it. I'm not sure why this would start all of a sudden, but it concerns me. What should I do or what should I look for? Are there settings that need to be changed?

A bluetooth serial failure has occurred?

Hi,
After playing around for a while, I finally got my Nokia N82 to work as a modem on my MacBook Pro using scripts from http://www.taniwha.org.uk
But after 30mins online I was disconnected and now if I try to connect again I get the following dialogue:
A bluetooth serial failure has occurred.
Failed to open an RFCOMM serial channel. Check if authentication needs to be enabled in your device.
The only thing I understand about this is the authentication part. My phone is set to automatically allow all connections from my computer.
Any idea what is going on?
Any help is appreciated.

I'll take a shot. Who is your cell phone provider? Did you look at the modem scripts in /Library/Modem\ Scripts for Nokia one(s). There are some. Possibly generic that would work. To make this simple, since it is late, #1 here is system log of my Panther and LG phone using one of above mentioned scripts.#2 And the link is an older one about doing the same type connection and the problems with Verizon. But then I never had same error message you got. I searched on that error and it appears that rfcomm can loop and the way to fix that is to bind to more channels which I am not sure how, since the only thing to change , it appears is in bluetooth preferences. I would not touch that, yet. The problem on configs, I believe, is the property is propriotory(spelling?). Or the channel is in the phone settings. Anyway I would try a different modem script in the Library and also check out the other links in #2.

Anyone know what a bluetooth serial failure is?

"failed to open RFCOMM serial channel. Check if authentication needs to br enabled in your device"
Can anyone help on this?

What are you trying to do? What devices? With Bluetooth you have 2 devices that you want to talk to each other. One tries to find the other and if it can't it says it failed to open a serial channel, that is, make a connection. Then it helpfully suggests that you might not have turned on (enabled Bluetooth) the second device.

IPad Serial Failure

My Mac is showing this message when I connected my iPad A Bluetooth serial Failure has occurred. Message says Failed to open an RFCOMM serial channel
Check if authentication needs to be enabled in your device. On checking under Hardware _ Bluetooth I see that under one heading for a mobile phone incoming
serial port 3 Bluetooth -PDA-sync RECOMM CHANNEL 3 reqires authentication can anybody help?

Thank you I am quite aware that you cannot connect a i Pad via Bluetooth to a Mac I do not wish too but what I do wish to do and have been trying to do for the past 3days is the delete/erase/remove what ever you like to call it an error message which I quoted in my first message Now if anyone can help me I would be very
thankful as this problem is driving me up the wall.I would add that my iPad has been accepted by the system and I find it very helpful mind you the arrow head does go off on a run about now and then. I just wish it would take the error message.

Bluetooth Serial and Cisco Console connections?

This may be the wrong forum for this, but network management was the closest fit i could find...
(First off, I agree that console connections are not preferred, SSH, HTTPS, SNMP all have their advantages, but when something goes down or stops responding to normal methods the amount of time and frustration that can be saved by not having to search for "that one laptop that has a serial port" or "my specific laptop that has the USB-Serial driver installed" is invaluable.)
With the proliferation of tablet devices (ipad, cius, samsung's proposed, etc.), add to it a serious lack of serial ports on most laptops/netbooks/etc being released. It's getting harder and harder to connect to console ports on cisco devices. USB to serial adapters fit the bill for now, provided you had the right drivers to run the adapter on your device (read: doesn't address tablets and smartphones).
I understand that the cisco console connection is considered "legacy" and that USB connections are becoming more popular with newer Cisco devices, but in the meantime it would be nice to manage my slice of the millions of "legacy" devices out there.
Bluetooth serial seems to hold promise, though the serial features of bluetooth aren't typically incorporated into most devices right now. What i guess I'm looking for is a way to manage my router and switch console ports from a smart phone or tablet device.
Has anyone seen anything like this out there right now?
I would think that Cisco would be interested in marketing such a feature with their new Cius, or an iPod or Android app. Even if it cost a couple of bucks for the adapter or the software, it would be well worth it to be able manage these devices in a pinch.
Thanks to anyone that can help!
JM

I agree, it wold be handy to have.
One thing some of us use is iSSH on the iPhone or iPad. Straight across the in-house wi-fi LAN if there's a working one in house or via the VPN tunnel if not. The use cases of no w-fi, no VPN or an unresponsive box are still not addressed by that solution though.

It delays 200 mSec from Tx to Rx at Mobile to bluetooth Serial adapter, why

I use mobile to bluetooth serial adapter.
It delay 200mSec from Tx to Rx 1 byte.
I use PC bluetooth to bluetooth serial adapter that it is normal.
I used StreamConnection, OutputStream and InputStream APIs.
How?

It sends 126 bytes to MTU size that is no delay.
I am trying for Rx.

Two Bluetooth Serial Ports - lots of RFCOMM errors

Ok... So I'm sure I'm a unique case here, but I'll throw it out anyway, just in case anyone else might be experiencing the same problem, or might know of a fix...
I'm trying to use two Bluetooth serial ports, a Bluetooth GPS and a ham radio TNC (think of it as an RF modem), simultaneously. I was able to do it twice, so I know it can work, but in getting to those two times, I encountered numerous RFCOMM errors mentioning authentication, other failed or hung up connection attempts (The Powerbook seemed to connect to the device, but no data flowed to the application), and even a few "You need to restart your computer. Hold the power button down for a few seconds..." (I guess you could call it the black screen error?) screens. Many times, I could get one device to connect and pass data, but the second one would cause errors. Sometimes I couldn't even get one device to connect.
The devices I'm connecting to are a Pharos iGPS-BT and a Socket Cordless Serial Adapter. The GPS comm settings are 4800-7-E-1 and the serial adapter is at 9600-8-N-1.
Like I said, I actually accomplished it twice, so I know it can be done, but it seems to be a LOT harder getting there than it really should be. Anyone have any thoughts or ideas?

Well, it seems like I've figured it out. I deleted the pairings (and thus the related serial ports), re-paired (probably not necessary; I probably could've just deleted the serial ports and re-added them), and I haven't had problems since.
It seems that the problems were related to the fact that I renamed the ports to considerably shorter names (i.e. bt-gps instead of PharosiGPS-BT-GPSRFcom-1). I've left both ports with their original names and have had no problems since.

General bluetooth serial adapter questio/ discussion (concept question)

Dear all,
I am working on a project which need to use my notebook (bluetooth enable) to talks to a "Willies bluetooth serial port adapter" which is connected to a microcontoller circuit to control other devices. So, I am trying to write a labview program which send a virtual serial port signal via bluetooth. Am I confusing you? Do you have any clue how to do it? Starting from a VISA vi, then some bluetooth vi?
I have not yet received the "Willies bluetooth serial port adapter", and I will receive it next week. My critical job now is to make myself able to do bluetooh data transfer, so I will have more chance able to do the real tasks next week. I am trying to use labview in my notebook to connect to my pda phone, does my pda phone need any VI ?? Any clue? I believe the notebook to pda bluetooth transfer is similar to the bluetooth serial port adapter. What do you think?

Third Party Bluetooth Serial Interface

Hi,
I have a third party EEG headbox with bluetooth connectivity using serial interface. I did the followings:
From Bluetooth, added the device that was successful. Furhtermore, two unidirectional ports were added to the device i.e. COM3 (incoming) and CoM4 (outgoing) - VISA
The device is successfully accepting the commands i sent with a beep acknowledgement.
The followings are the issues.
The device is not responsing with any data i.e. nothing coming to pc/ laptop because of the device is using two unidicrectional COMs.
Query:
How can i assign the one COM to the device so that i can receive the bytes as well.
Regards,
Abdul

Bluetooth hardware failure, cause by using a usb bluetooth adapter

My laptop is MBP 13" early 2011, after using a usb bluetooth adapter( built-in bluetooth had compatiblity problem with my mobile phone) and unplug it, and then found the built-in bluetooth is not working any more, it can search devices, but it won't establish connections or pair with other devices. At firs I thought it was the bluetooth driver or configuration problem, I try to reset factory setting using the develper tool Bluetooth Explorer, then reset kext file, even tried installing a new lion, but the problem remains. So I think it's not driver/configuration problem now, it's hardware failure, but wait.. just caused by using other usb bluetooth adapter? I really can't understand why apple will let such thing happen....

it turns out the hardware is fine , the problem is solved after resetting SMC : http://support.apple.com/kb/HT3964

Cannot delete bluetooth serial port! going crazy! help!

Brief background-
I want to sync my Treo 680 with my intel iMac. I have never gotten BT sync to work with any mac or any palm I've ever had. But this time, somehow I did.
And now it's dead again.
I have given up on troubleshooting, and just want to delete all bluetooth profiles, devices, etc that I have created, and to start fresh.
The thing is, they won't delete.
In the bluetooth section of System Prefs, there is a sharing tab.
Under that I have:
Bluetooth file transfer
bluetooth file exchange
bluetooth-PDA-sync
PalmBT
the first three are not delete-able since they came with the system, I guess.
"palmBT" is one I made, that is a duplicate of bluetooth-pda-sync.
I just want to delete it altogether. They are both turned off, but it doesn't matter. if i try to turn either one on, I get an error. I forget the exact words- something about transport monitor could not complete my request.
Not sure if this is an OS problem, or a palm hotsync problem. But like I said, I DID work for a while. I have no idea what may have changed to break it.
So I select "palmBT" and click "remove serial port service" and get this error:
"You are attempting to remove a port which is in use. Quit the application using this port and try again."
What does this mean? The port most certainly is not 'in use'! If it were, I wouldn't be here looking for help! There are NO applications running- what am I supposed to quit?!
Help!!!

Ooh, god I hope not... just for this?! If that's the case I'll give up on BT sync and just stick with USB.
if I do that, it will be the THIRD time I have had to wipe this hard drive since I got the computer in MARCH.
I am still not fully recovered from the last time (but at least I have a backup now)
there must be something else to try- anyone?

TS3048 Bluetooth keyboard failure

Same day failure of Bluetooth keyboard vs. IPad.
After going through 3 sets of batteries, and verifying the failure with another "older" Bluetooth keyboard of the same make and model.
Pushed the power button as I have hundreds of times prior.
Green LED stays on for 4 seconds, then goes out never to return till I do it again, then the same exact response.
Not sure what the failure is, but if I press and hold the power button, it will flag the process of pairing, but it will not pair due to the lack of its ability to stay on for a sufficient amount of time.
I suspect the segment that allows for the device (battery sense) detects insufficient battery life and thus drops it like yesterday's news paper.
Please advise and thank you.

Hello:
Reset the SMC.
If that does not help, take in back in for service.

Bluetooth connection failure

Hya all,
I want to send something from an old phone to my blackberry but everytime i try it says connection failure... The bluetooth is switched on etc and i can actually send things from my blackberry to other phones just not vice versa,
Can anyone help me?
Solved!
Go to Solution.

Does your old device have Bluetooth? In my experiences Bluetooth is hit or miss with older devices and BlackBerry's
If someone helped you give them kudos. Research all info!
