Learn about vigilant mode.

Added:

  • This changelog and a patch level in versioning.
  • Handling of unsolicited messages from modem as needed with the
    newer pycom firmware.

Changed:

  • Update pycom firmware dependency to version v1.20.2.r4. This version
    is tested with modem firmware version 41019 and 41065 (NB-IoT).

Fixed:

  • Rework of modem communication module.

Known issues:

  • When the mobile network signal is weak the modem gets quite busy with
    handling connection losses and reconnects. This reduces the
    reliability of the communication between modem and the microprocessor.
    Characteristic of this situation are SIM commands failing with APDU
    exceptions such as '6D00' (unsupported command) and similar because of
    transmission errors. A solution to this problem is to position the
    device in a place with better network coverage.
