FONA library SLEEP MODE

Post by wex »

hi, I used the FONA library to support the board with the SIM800L module. Everything works fine except waking from sleep. After ESP wakes up, GSM does not work, no AT message. Does anyone know how to wake up GSM after sleep?

@wex,

Did you try sending this AT message through the serial port? I see on another forum that it worked for that user.

Code: Select all

 AT+CSCLK=2
