I am developing a HF device that will connect through Blutooth to the Nokia 3600. My problem is that I can connect to the phone as a HF Profile device but cannot initiate the HF session. I was then able to send AT commands to the Nokia 3600 phone such as "AT+CIND=?"(indicators supported in the Phone)I receive the response I expect, but if I try "AT+BRSF=01"(Indicated to the
phone supported HF features) I receive an error.
