Hi,

 When i use my phone (LG KU990i) for a connection on my application (HFP profile, headset profile and intercomm profile in SDP_RECORD ok).

I receive SPP_link_establish on local port.

I do a SDAP_Connection and after a SDAP_Service_Browse where i can see rfcomm port number 0x10 for LG_Sync_SPP.

After 3 seconds, my phone is disconnected.

I'm looking for the process for any phone ( if it's not different between manufacturers !!! ) for the connection.

My application receive calls and generate calls in Hands Free mode.

 If someone can help me.

Thanks for all

I think you're not using our library, what are you using?  Anyway headsets generally will talk to only one phone (aka "audio gateway" device).  That's partly for security reasons once its bonded to your phone no hacker can get it to send audio to them too.  You'll have to set your PC as the "audio gateway" device.

 Hi,

 

I'm working in assembler with a PIC controler connected to an ARF32 module. This is my Hand free application an connected to my phone (LG KU990i) i try to send call. Receive calls are ok.

 For security, i'm with the lowest level. I use only pin code.

When the phone try to connect to my application it's ok, but after 3 seconds, it released the link. So i scan port 1 to 31 with link establishment and after an AT command. But it answer with ERROR and not OK on port number 3. This port is not present when i browse all services in the phone. When a call is receive, i have RING and with AT+CKPD=200 the SCO link is establish. If i call with my phone, the communication use the hand free equipement. But When i try to call from the hand free equipement, it answer me with ERROR.

 I don't know if it's clear, but this is my problem.

 Thank's for all, and i try all other level security in my application.
