In‐Circuit‐Debugging - rotorman/CyberBrick_ESPNOW GitHub Wiki

The development and testing of the code in this repository was carried out using an ESP32DevKitCv4, paired with a radio running EdgeTX firmware.

For in-circuit-debugging, ESP-Prog on ESP32DevKitCv4 target with the following hookup-scheme was used:

For successful connection, use ribbon cable for the ESP-Prog JTAG connector and keep the cable length less than 20cm (8"). Also, the cable connecting ESP32 development board to the radio, should use short and ideally twisted wires.

Further detailed description about the Espressif ESP-Prog debugging adapter can be found at the Espressif's docu pages.
