Tell us about yourself!
Sorry AroshaD I did not see your message...I will try to build the circuit. Have you tried it yet ?I am surprised because the module appear in android to be only a headset. Maybe after I connect the pins according to the diagram it will transform into a freehand.
Hello !Thanks for your answer. Unfortunatly, I can't find any link or image in it... So what did you found ?During my research for solving this problem I first found that : http://openrcforums.com/forum/viewtopic.php?t=3803where I understood that the chip is not in a "freehand mode" and that we could set it to such a mode using the serial communication, but may be too complicated for me :(So one may connect a computer to the serial port and send the order "Unmute the mic" from http://www.electrodragon.com/w/images/4/4b/BLK-MD-...which will turn it to a freehand instead of a headset in android point of view.I'm not sure of what I say !see :for how to send message to the chip...
Hello,first of all thanks a lot for this very usefull tutorial !I would like to know if you had success with the microphone. I tried, but could not get it working... I used a microphone from an old phone soldered to MIC and Ground.I found there (http://www.eevblog.com/forum/beginners/noiseinterference-on-bluetooth-audio-module-(blk-md-spk-b-)/ ) that "the microphone is just not enabled for this version", which if true would be really bad to have a pin named MIC and not mention in the description that the mic is not enabled...What are your experiences ?Again, excellent tutorial :)PE
