  1. Issues List
    1. ATMega issue

Description: Get no response from BoSL Serial, looks like ATMega is dead. This happened twice on 2 boards.
Test The first time, the code used RTC for deep sleep. To figure out it is not an RTC issue, the second
time used watchdog timer for deep sleep.

    1. SIM7000 issue

Description When Sim7000 is power on, get no response from Sim7000. Test Tried using different baud rates talk to Sim7000.
Tried keep sending "AT" to Sim7000.
None of the above method work.
After pressing reset button, sim7000 started to response.

    1. Net register issue

Description Some boards cannot register to network. Test Tested 6 boards by using same code, 4 of them cannot register to network.
Keep receiving "+CREG: 0,2", resetting sim7000 and re-connecting to battery won't fix it.
