ESP32 LoRa (v2) rebooting hard 0.0.4

Hello people!

Recently I´m updated the hardware version and I had a surprise… The firmware I have made with hard ver 0.0.2-rc1 no longer work. Apparently ESP32 rebooting when I tried to send a string by LoRa.

Executing a downgrade again the firmware back to work.

I´m new in Arduino program and I have no idea what hapens…

See the debug below::

Can you please upload your example code here? I want test at my side.

Hello Friend,

See below. I think is a problem with simple solution but as I said I´m noob and I don´t know what happen…


That is terrible to read.
Please format your source code

Hi friend,

So sorry for this. I don´t know how can I format it to help you but see the link below.
