Hello everyone,

I have a school project that is based around sending data from some sensor to ardupilot.

I failed sending defined data like plain number. Im using pixhawk 6c, arduino uno or ESP32 devkit board.

I based my attempts on examples from I2C slave.

This is the code i used.
test.txt (352 Bytes)
test.lua (2.2 KB)

If anyone would have any idea. Thanks in advance.
