Thank you for the clarification. If I need to I will do it in NVS. My worry was whether it was being done by the Arduino ESPNow library or the WiFiESPNow library I am using

Thanks for the prompt reply.

I am using ESPNow as a peer to peer connection. Each of 2 ESP's send information to each other wait for a custom ACK and go to deep sleep for a fixed time They repeat this on wake up. I do this around 5 times a second However as I am in Deep sleep, I have to re-initialize ESPNow on each wakeup and a...

I believe that if they are TTL level outputs my 5V logic would be able to correctly work without level conversion as I am using ESP for outputs only and not inputs. But if ESP ou...
