I have HP iPAQ 514 with TomTom 7 installed on it, my goal is to hear all the TT's voice instructions through my bluetooth headset.
I've experimented with several settings as my headset is A2DP enabled, the result is that my phone is not fast enough to run TomTom and encode A2DP at the same time, so in the bluetooth settings of the phone I've unchecked Wireless Stereo and left only Hands Free checked for my headset.
Through standard hands-free profile it works, but with lags, i.e. I hear about 1-2 seconds sound from the phone speaker, then it's switched to my headset. Sometimes, if an instruction is too short, it switches even after playing it, so I don't hear anything. After a few seconds of inactivity, it switches back to "standby" mode.
I've found out I need to keep the connection between phone and headset "alive" to get rid of those lags - e.g. by playing music in the background, then there are no lags as the connection is active. But playing some sound (even playing "silence" just to force permanent connection) means extra load for the processor and the memory, and is very unpleasant. Is there any other way to keep my phone permanently connected with my bluetooth headset, not in just lag causing "on-demand" mode?
Thanks a lot.
