I'm trying to control pwm signal by at command in ESP8266.
So, I applied modified user_light.c/user_light_adj.c to at firmware source tree.
(base source tree: esp_iot_sdk_v1.5.1/examples/at)

Compiling and downloading is ok but it seems not working as I expected.

AT command I/O is too laggy after calling pwm_init() and pwm signal waveform is not stable either.

Is it not allowed to using pwm API with at command firmware?
Could you show me working example or documentation about this?

Thank you.
