ifnow
A Linux network interface device for communication over the ESP-Now wireless broadcast protocol.
NOTE: This is EXTREMELY work in progress and as it requires root permissions is not recommended to be run unmonitored.
Build
git clone https://git.oit.cloud/morgan/ifnow.git
cd ifnow
mkdir build
cd build
cmake ../
make
This should result in the ifnow binary in the build directory.
Usage
This is two steps, first setting up monitoring mode (using aircrack-ng in this method). You will need to determine
your wireless interface name and replace if different from wlp2s0 in the example. You will also want to set the
channel to match the ESP32 configuration.
sudo airmon-ng start wlp2s0
sudo iw wlp2s0 set channel 1
./ifnow wlp2s0mon now1 10.10.0.13
The interface is now up as now1 and you should be able to write to this interface. In theory pcap can
be used to intercept raw packets but if used with LwIP on the ESP32 end, which can be accomplished with
esp_netif_now, any IP stack should work. Has been testing
with UDP and some CoAP. There are definitely still issues with parsing some incoming
packets.
