ESP-NOW frequency hopping spread spectrum

Hi,
Just wondering if it could make sense to implement a Frequency Hopping mechanism between 2 esp32 connected through ESP-NOW?
That is to say changing the wifi channel before each data packet transmission in a known/predifined sequence across the 14 available channels.
I made some test, changing ...

Hi,
I'm playing with mcpwm in order to use it later with a stepper motor. I made a very simple sketch (on arduino ide) where I setup a basic mcpwm to generate a pwm signal (first 1khz, then 10khz), stop and restart, etc... And I try to sort out how to manage interrupts.
And this is where I have a ...

Re: Serial2 read error but available>0

Hi,
I confirm: After long long long investigations, I arrived to the same conclusion.
Serial2.available() sometimes returns wrongly values>0, so with no data available.
I'm using Serial2 between 2 esp32.
I also have the case when Serial2.available() returns values>0 and the next Serial2.read ...
