Life saver. Went through a bit of pain(2hrs) with the function definition differences for esp_now_register_recv_cb for ESP32 and ESP8266. Was doing the same dance with the printing the full error on notepad++ to work out what was required, when I thought I'd check you tube. Bingo great definition of what to do!

This is great info! I have a practical project where everything will be two way communication, but my controller will be an ESP32-S3 box, with a screen and some buttons plus my IO and each of the other devices are D1 MINI Pro boards with the external antenna because, for what they are, they must be inside a steel box. I did manage to get the ESP8266 example talking to the ESP32 example by figuring out that the examples used different channels *and* different SSIDs. Being able to just use the SAME example on both ends is golden!

Those two sketches I used in the video had been working great with esp32s, but when I tried using it with a couple esp8266, I was getting all those errors. I was able to google and find examples of working ESP8266 ESP-now sketches, but I really found working through the errors line by line helped me get a better handle on those differences.

Thanks Chainsaw! I definitely agree with you, pointers can wrack the brain at times (just last week I was reaching out to a friend trying to understand some errors I was encountering and it had to do with my mishandling pointers). We should have a couple lessons coming it in the next couple months about using pointers. Thanks again for the comment and recommendation.

@@programmingelectronics probably easier to make a gateway, read the serial or I2C on the pi w and write to it from an ESP. You could in theory rip the code from the ESP-Now c libs and try and get it to work on a pi, I doubt it's been been done and it's probably not hardware compatible. But a gateway is easier to setup. You can do that with 2 esp's connected by Serial1 or i2c and let the pi access it over regular wifi as well.
