LoRa module control remote with ESP32 S2

[costy-19]

Hello everyone!

I'm working on an application to monitor environmental data. I use an individually created LoRa module on the Arduino nano architecture with the ATmega 328PB microprocessor. The sensor connected to the module constantly transmits temperature and humidity data via TTN.
The problem is that after about a month the module freezes, requiring a manual reset. What I want to do is implement an ESP32 S2 to create a remote reset function (remote control). What tips do you have for implementation? I mention that on the LoRa module the DTR pin leads to the reset pin. also, will the ESP32 require a different power supply?
Thank you!

Sounds like a code problem. Those can be diagnosed and fixed.

Use of Strings is often the culprit.

Add a watchdog, adding another board just doubles (at least) the odds of failure.

Not sure what you mean by that.

As others have suggested best to fix the original problem rather than add another one.

Perhaps post your code and a schematic ........
