Hi All, I am new to BT so hopefully my problem is simple to solve. I am using a Blue Creation BC127 with Melody v6.0.48 and need to connect this to a BT Headset to realise a bedirectional audio comunication The headset is a BT2.1+EDR unit that supports HFP1.5 and A2DP. The BC127 supports HFP1.6, A2DP, ... Problem 1: - using the open command I can connect with an A2DP profile. (but I need the HFP connection) - Connecting with a HFP ("open xxxxxxx HFP") always tells me "OPEN_ERROR HFP" Is there some possibilitie to check what's the problem here? I can connect the BT headset to a cellphone without problems Problem 2: When sending some commands from the latest manual I receive "ERROR 0x0012", "ERROR 0x0013", "ERROR 0x001A" but after searching for a longer time I still can't find a manual that describes error codes. Could somebody give me a hint how to solve my problems? Regards, Christian
