Table 4-6: GPIO Pin Description
Which gpio should I use
I have tried gpios - 2,7,8,13,21,22,23,24,25,28,29,30,31,32,33,35,42
using at commads - AT+WIOCFG==,4,1,1,0,0
AT+WIOW==,
I do know the following connection
GPIO42 - Controls pin 24
GPIO13 - Controls pin 26
GPIO33 - Controls pin 25
GPIO8 - Controls pin 27
and gpios 36,37,38,40,41 using legato apps “streamMedia”.
I couldn’t disconnect the Audio jack or connect PCM (pins on extender 36,35,34,33).
I have also tried to active MuxControl from GitHub - mangOH/MuxControl
I have got on ssh
Connecting to service …
Error: Can’t connect to muxCtrlService. Is it running?
