Hi.
Thanks for letting me know.
I probably cut those lines by mistakes when copy/paste the code for the explanation section.

I’ll fix the code.

Thanks

Hello,
MicroPython: ESP-NOW with ESP32 (Getting Started)
I created the One Way Communication application using 2xESP-WROOM-32 from ELEGOO.
The transmitter worked fine, but the receiver didn’t display the message in Thonny’s Shell.
After some searching, I found the following line in the code explanation for the receiver:

if msg:
print(f”Received from {host.hex()}: {msg.decode()}”)
This line is not in the receiver code!
After inserting this line on line 52, everything works perfectly. Hopefully, this is on the right place.
It’s probably a Printing error

Kind regards
Roland

Hi.
Can you tell me which lines you’re referring to so that I can fix the code?

Good evening.
Two lines were missing in the receiver code, which are listed in the “How the code works” section. In Shelly, it did not print the complete message.
Otherwise, perfect and thank you.

Hi.
I’m not sure… Because ESP-NOW needs the Wi-Fi module on, I guess it won’t work.
But, try it out, and then, let me know.

Thanks for the great tutorial.
Question. Is it possible to use the ESP32’s second ADC and ESPNOW at the same time? I know it can’t be used when WiFi is being used, but what about ESPNOW?
Thanks,
Ian

I don’t think so.
ESP-NOW is used to send small amounts of data, which is not the case for sending live video.

Would this work sending live video from an ESP32 Cam board?

It’s important to note that ESPNow.stats() runs on ESP32 only – not on a 8266.

Hi.
It depends on the environment.
You’ll have to test it youself.
In open-field, next to the sea, we got a communication range of about 220 meters.
