BoSL Board Debug

Stop logging issue

The BoSL Board stops logging from time to time is a big pain. The team decided to find the root cause and solve the problem.

Trouble shooting history

31th May 2023

20 BoSL boards were setup for trouble shooting. 10 run the original BoSL_logging.ino code, each one with a tag (OLD_1, OLD_2, ...), let's call them OLD group. Another 10 run Dave's new version code BoSL_VEL_Dave_290523.ino, each one with a tag (NEW_1, NEW_2, ...), let's call them NEW group. The major difference between OLD and NEW group is the NEW group's code delays longer to pull Sim7000 powerkey down to power off Sim7000. Because we suspect that some MCUs run slowly and the delay(1200) is less than accurate 1200ms, so sometimes Sim7000 may not really power off and the result is the Sim7000 runs out of order.
