on the wiki page of the LoNet breakout, i dont’really understand this sentence about microphone :
“Microphone: this is the reserved interface for 2.8V microphone. By using the microphone, you can make voice calls and collect speech data around the module.”
Reading the design schematics :
seeedstudio.com/wiki/images/ … ematic.pdf
I understand the MICIP and MICIN are connected to the SIMCOM808 module, however there seems to be no connection to SPKIP and SPKIN.
Does it mean there is no way to get a speaker output of a voice call from this breakout ?
(otherwise, i just tested sending sms and getting GPS info, and it works great)
