@MacWyznawca
This feature works well on my side,

Are you using idf.py monitor? Or can you try a different terminal or monitor tool?

[MacWyznawca]

@esp-wzh As you can see I'm using a normal IDF (you can see in the window bar at the top).
As I manually typed the end-of-line characters in the mentioned function, it helps, although not always.

[esp-wzh]

OK, I reproduced it, seems it caused by Time field string too long, will give fix soon.

[MacWyznawca]

@esp-wzh It is possible that the problem does not occur when you use a small terminal window (80 characters). However, I can't work that way.

[MacWyznawca]

Great! Thanks @esp-wzh

This patch can fix the problem, thanks for report! @MacWyznawca

Thanks @esp-wzh Works! ;-)

By the way @esp-wzh, could you suggest where to look for help in lowering the power consumption of the ESP32-C3? I'm making a light bulb, but the power consumption is 0.66, and the EU requires less than 0.5 W. Note: we are only using ESP-NOW.
I use combinations with esp_now_set_wake_window and esp_wifi_connectionless_module_set_wake_interval, which lowers power consumption, but unfortunately causes sometimes no response (transmission errors).

Please ;-)
