Yes, the threshold field is an 16-bit one.

@ESP_igrr I tried larger values for the idle threshold but when I have those values I only get channel 0 error interrupt. There must be something else wrong with my code.

Can't run your code here to test (it doesn't compile without dependencies), but another thing is that you aren't clearing carrier-related fields of rmt_config. So the RMT may be expecting to see a carrier wave.

Was this fixed? Think I might be having the same issue here: viewtopic.php?f=13&t=5122

When I increase the idle_threshold to 12000 or beyond (including 65535), I get an error. I am trying to understand the error code. I get similar error codes by putting in frequencies that should work too.
