SARA N310 deepsleep mode


Do SODAQ have any example on how to use the new board in deep sleep mode? The difference between sara N211 and N310 seems to be the PWR_ON pin.


  • Baud 115200 doesn’t work with PM3. The module will just reply with “crap” AT response. Changing to 9600, then I can use PM3.

  • Socket connection is not stored after going into deep sleep. Every time the module wakes up, I need to open a new socket. With SARA N211 this wasn’t needed, the socket was still open after deep sleep.

  • Received socket data is lost after deep sleep. I need to read the received data before going into deep sleep. This was not a problem with the SARA N211, it kept the data until it was read or socket was closed.
