GE866: Error when reading IMSI

3 thoughts on “GE866: Error when reading IMSI

  1. I’m testing GE866 and came to an error while reading the IMSI with at+cimi.

    Same startup procedure works with GL865-QUAD and other modules.

    I have verified, that "at+cimi" is generally working at a later time in startup, but I expect that it should work after "+CPIN: READY" is returned.

    1. At power on SIM initialization starts reading different SIM files, phonebook, SMS. it is possible that even if the SIM is READY, the IMSI is not immediatelly accesible.

      I would suggest to insert a delay of at least 1 second .
