I'm getting my ESP32 into a mode where an esp_now_send returns 12393, which, in turn, esp_err_to_name() tells me is an UNKNOWN ERROR.
At the sime time something seems to have clogged esp_now, as no messages are going out.
Unfortunately this is extremely hard to debug, so maybe someone knows what have might set my system into this state?

Re: esp_err_t 12393
to answer my own question: This happens when you call an esp_now_send before adding the recipient address as peer.

For reference, the ESP-NOW error codes, including 0x3069, are defined in esp_now.h.
