Treo 650
Been away for a while. The unit I tested was the Treo 650 GSM, and only the Sprint version is currently available. You can get so far with getting it to work, but please post your experiences here and we'll see if we can figure it out together.
To Pair:
Follow all the regular instructions, but the Prius won't return to the menu (or register the 'phone) after pairing, even after the 650 thinks all is well.
To un-stick the Prius, make a call on the 650 within a few seconds, and the Prius will confirm pairing and register your 650.
To Connect the 'phone:
Power off everything. Restart Treo. Boot up Prius.
650 will connect, you can make and receive about two calls, then the 650 or the Prius will disconnect.
To reconnect, stop the car then re-select the 'phone. Drive away again, make a call, go to the beginning of this sentence!
I tried pairing an HP PPC 'phone with BT, and got similar results (I can't beleive that there's a line of code similar between the implementations of BT stacks on both), so I'm blaming the Prius.
More soon.
