I'm using a sim 808 module to receive and answer calls.
I was able to use the microphone with a MIC I had of my headsets with no problems
but then when I tried to use a mini MIC, on the other end of the call I only hear static noise.
I thought that my MIC was not working but then I got another one and I was having the same problem.
I can use the headset MIC but I really want to use the mini MIC to answer calls with the module
Nice pictures but not much use. The extra clutter obscures what is there. Post links to technical information on each of the hardware devices. You are using different MICs, the pictures show they look different so they must be different??? What type are they? Post a block diagram of how this is going together and what is connected to what include all power and ground connections as well as power supply(s).
