hi @pytrackuser1 and @jcaron
I've run an similar experiment, on Pysense, for some 12-14 hours and it didn't failed (sleep cycles were 20sec). I've used a 2Ah battery, and recharge it once during the experiment.
I've met such situation, but the battery was weak, 3.6V showing on pysense.read_battery_voltage(), indeed it did not wake up.
You could log into NVS last value of: the battery voltage, number(count) of restart, time from RTC, maybe we notice a pattern. Computer could go into in standby, and minimise USB power source; but you said you've used a power adapter...
One question, after the block, you just cycle power and it works fine, isn't it?
OK, I will try to monitor power usage, maybe I can detect something.
To disable Pybytes:
we’ve just released v1.20.2.rc3, which supports the method pycom.pybytes_on_boot(False)
for the previous versions, there are 2 commands:
>>> pybytes.smart_config(False)
>>> pybytes.set_config("pybytes_autostart","false")
