Hello,
I'm using NeworkStream.Write/Read methods to communicate with a BT device over Handsfree profile using AT commands. Everything works well except one command that displays text message on the device display. The device receives the command but it's cut down to 42 characters - only first 42 letters of the command is accepted and processed (this is not a limit of the device). (I tried NetworkStream.Write/BeginWrite, Socket.Send. All with the same result.)

For example
\r\n+XXXXX: 1,12,\"1234567890123\",\"first test parameter\",\"second...
Only "1234567890123" and ""first test" is received.

Is there any reason why 42 chars can possibely be any kind of a limit?

I'm not familiar with this specific capability is it part of the HFP spec or specific to the device?

Peter
