ofxESPNOWBroadcast

Experimental add-on. Linux only.

Description

This add-on enables you to send ESPNOW from a Linux computer to ESP32 and/or ESP8266. This way you don't need a USB⇿ESPNOW-bridge device.

Usage

1. Put your WiFi card (the example below uses _wlp166s0_) into monitor mode. 2. Set the channel on which the ESP's listen for ESPNOW.

		systemctl stop NetworkManager; # Otherwise the card goes back into Managed mode. 
		ifconfig wlp166s0 down;
		iwconfig wlp166s0 mode Monitor;
		ifconfig wlp166s0 up;
		iwconfig wlp166s0 channel 1; 
		iwconfig wlp166s0; # To see if the card is actually in Monitor mode and on Channel 1
   

3. Run the app as root, otherwise the ESPNOW_lib won't work.

Also check the Linux-ESPNOW repo for README's (also in the seperate directories).

This is basicly a copy of Linux-ESPNOW by Thomas Flayols. Therefore the same license applies.

Test

I've tested this on my Framework (13) laptop running Linux Mint 21.2. This model has a AX210 WiFi chip.

Warning

Some WiFi cards don't work, I don't know why. My Ralink RT5370 doesn't seem to do the job. An issue I've observed is that the raw packet misses 5 bytes compared to the packet send out.
