Kernel panic using RH_ASH library

Postby tomxygen » Mon Jan 28, 2019 8:07 pm

I'm using a 433Mhz transmitter and receiver to send data from an Arduino nano to an ESP32, using the RH_ASK library, a sublibrary of RadioHead.
The problem is that as long as I use the sample sketch, everything works fine, but when I implement the library into my project, when I add the instruction driver.init(); I run into a kernel panic in the serial monitor:

Code: Select all

Most likely, you may have to edit the library to work with ESP32.

Do you have debug enabled? There should be more information available for a Guru error.
