Re: [Bluez-devel] At commands not available

[Luca Pizzamiglio <pizzamiglio@cefriel.it>]

Hi Dirk. I've tried your code on my system (bt dongle with i-mate SP3
phone), but my phone close the connection during receive.
I'm subsantially sure that the channel is right. When I try DUN channel
I obtain ERROR response, but when I use HF profile, the phone close the
connection. I obtain the same behaviour with HS channel.

Someone could help me to solve this problem?

thx in advance.

Cheers,
Pizza
