Motorola H700 automatically disconnects.

I am having a lot of trouble with my Motorola H700 headset. I can pair easily, and the headset even shows up in my System Preferences, but I get the "Bluetooth Audio Failed" or "Disconnected" errors when I try to use them as Input or Output.

I noticed in Bluetooth Preferences that in the Devices tab, the "Connected:" spot goes back and forth between Yes and No, it seems for no particular reason as the headset sits 6 inches from the machine. Eventually, it just stays disconnected.

Any help is much appreciated.

I have a Motorola HS850, and have the SAME issue; I can pair it, but whenever I go to USE it, it immediately disconnects. Very weird. I considered the BT firmware upgrade, but when I look at my system profile is shows my BT firmware as being in the 1.7xx range, and I an hesitant to do a firmware upgrade that appears to be several revs behind mine, or is the firmware update naming convention completely aside from the production build numbering schemes? And further (stand-by for a rant)... WHY IS THIS SO DARN DIFFICULT to begin with ? Any help will of course be very appreciated...

There is no naming convention – the Bluetooth guys love to confuse people.

The Apple Bluetooth software is at 1.7.0 at the moment with Mac OS X v10.4.5. The Apple Bluetooth Firmware updater is at 1.2 and installs firmwares of 2.x on your Bluetooth module. I am not sure, which firmware you have at the moment, however, the Apple Bluetooth Firmware Updater will not downgrade your firmware. Either it fails or applies the latest version.

Although I recommend to try the updater once, I doubt it will help. This is a common problem for many users, however, I myself have not experienced this issue with five different headset models so far. So I have no solution to this.

I thought I should update all of us with some new info. I returned my Motorola HS850 and purchased a Nokia HS-26W, and it worked perfectly the 1st time. For what it is worth, it's box specs indicate it is BT 2.0 compatible, and HS 1.0/1.1 compatible, and it was on sale at CompUSA for $39. It paired 1st time, showed up in all the correct configuration menus correctly, and I must say sounds better than the prior unit did (the 1 time I used it). FWIW, you may want to try this unit. I also had NO "hung" preferences panes like I did with the other unit. (I'm just guessing but I can only attribute the difference to the BT 2.0 compliance, even though we'd expect OSX to drop-back to the level the HS can accomodate.) Any way, I'm a tad happier now... I'd be curious to know if anyone else finds success in switching to this adapter, just cuz' I am curious! Best of luck to all.

I use the Motorola HS810 (version 1.1), the Motorola HS820 (version 1.2) and Nokia HS-26W (version 2.0) successfully, too. However, i do not like the latter because it is not very scratch proof, has the new small Nokia connector, no Nokia large to small power-plug adapater (CA-44) in the box and it is Bluetooth visible all time. No good Bluetooth citizen.

It is not related to the Bluetooth version. There must be something else. Perhaps it is a problem with Sniff. I have no idea.

Alexander, good feedback. (Oh, BTW my Nokia HS-26W did include a step down adapter in the box, just FWIW) I noticed this sequence of events this morning(generally speaking): I powered up my PBook with the (Nokia) headset(HS) left powered off. Then, after charging the HS I powered it on. Then, all the "problems" from the past re-occurred, and of course I was very perplexed. Then, I powered the HS on and powered the Mac off/on via restart. Viola, everything worked as well as yesterday (see my previous post). I am beginning to wonder if the "problem" in some/many cases may be related to this kind of 'sequence of events', especially considering the fact that you have been successful with all of those different HS. Perhaps something as simple as a "general usage guidelines" would be useful. Dunno. Anyway, I am probably gonna be more scarce 'round these parts, although I will check-in from time to time, mostly because I seem to be off and running with my HS needs satisfied. Thanks to everyone who has helped in general.

Very good work.

I am able to reproduce this here with my Nokia HS-26W and a D-Link DBT-120 Bluetooth USB adapter. Although, there is an easier trick than rebooting. Simply wait around 10 seconds after turning on the headset and before using the first time. This worked here. When I used the headset immediantly after turning it on, I get these Bluetooth Audio failed messages.

Nevertheless, if you get the Bluetooth Audio failed message once, you will get it all time later. Rebooting the Mac helped than. However, I have not tried if sending the Mac to sleep and/or logging out and in helps, too.

Great work. Lesson learned: Do not use the headset immediantly after turning it on but wait some seconds or reboot the Mac. At least we have a workaround.

This might be, because a Nokia HS-26W connects to the first paired device rather than the last paired or used device after turning the headset on.

Count me as another with this problem. I bought the H700 partly for use with my Treo650, but also for use with my MacBook's iChat during audio/video chats.

I have tried everything I can think of: turning off my phone, unpairing the headset from my phone so it won't look for the phone when I turn it on, etc. All seems to go well, but as soon as I attempt to actually USE the headset, whatever process on the Mac that's trying to access it just HANGS and I have to force quit.

I'm having the exact same disconnect issue with two different motorola bluetooth headsets:

H700
HS810

on on both my MacMini PPC and Macbook pro. Pairing is succesful on both, and I've run the firmware updater on the Mini but they fail immediately when opening the BT preference pane or opening any application with audio.

When I run growl w/ hardwaregrowler and try to connect one of the headsets, it goes crazy with an endless loop of near- simultaneous "Bluetooth Connection" "Bluetooth Disconnection" notices. This seems to indicate a problem with the handshake...but that's pure speculation.

Both headsets work fine with both my windows laptop and two mobile phones, so this is clearly a compatibility issue with the Apple hardware/firmware. This is odd to me as all products involved are bluetooth certified and supposedly follow standards.

I have to admit I'm very disappointed that I've had to sink so much time into this issue to no avail when the headsets work just fine with my old windows laptop.
