I have created a minimal test sketch that shows the issue, and have also reported my problem on Github, see https://github.com/espressif/arduino-esp32/issues/1993 .

Just an observation that I made during further investigation: The error only appears if there is actually an IR signal coming in. So, as long as there is no incoming signal, there is no error, even after enabling (i.e. installing the IR recv rmt driver config), but as soon as I activate my transmitt...

Hello everyone, I have the following issue with an application that uses the RMT module for infrared transmission and reception (code adapted from the esp-idf example on sending and receiving the NEC protocol ( https://github.com/espressif/esp-idf/tree/ee0ebc1/examples/peripherals/rmt_nec_tx_rx ) fo...

Hello everyone, The API for the RMT driver has a rmt_register_tx_end_callback() which allows to run a user-defined callback after RMT TX has completed ( https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/rmt.html#_CPPv228rmt_register_tx_end_callback15rmt_tx_end_fn_tPv )....
