Hi, Well for the moment its even worse on the HTC Desire, I cant even connect to using the SPP profile!!!
I need to spend a little more time to gather more info but its not looking good :-( My understanding is that the Desire sports the same hardware as the Nexus 1.... I would have thought Bluetooth was thoroughly tested on the Nexus 1. Regards, Serge On Apr 13, 11:43 pm, Rafał Grzybowski <[email protected]> wrote: > Serge, > > Thank you for the reply.
