I have more than 200 hundred wireless stick nodes spreads in my company.
40% of then just stop to work after a days or months.
I Just stops to work and start to consume to much battery.
They are LoRa nodes connected to adxl345.
I’m using am timerAttachInterrupt in order to reset the module if it blocks somehow.
Can you give me any suggestion? This is a big issue for me.
