I am giving up on Puck =(
When it works, it is reliable (apart from the battery drain, but that could be due to the LED stuck on)
But after some time it just goes off the air and no way to connect/restart it remotely. The only fix is to yank the battery out. Gave up on the battery option and using a cable to 3.3v out on the ESP32 board that sits in the same box (as BT was not powerful enough to be read from outside the metal box, though WIFI on ESP32 is ok, which uses the same frequency). But still no luck - works for a few days and then just dies.
I have added nightly reboot already, just to clear any RAM/cache issue it may have. So running out of options. Given that I have ESP32 by the meter box anyway, I will just have to modify the code and use ESP32 as a main device
