With the `ESPNOW` PJON strategy, up to 10 ESP32 or ESP8266 devices can use PJON to communicate with each other over

You can also choose between Access Point and Station mode. To switch to Station mode, define CONFIG_STATION_MODE before
including PJONESPNOW.h.
```cpp
#define CONFIG_STATION_MODE
#include <PJONESPNOW.h>

The ESPNOW strategy will send a broadcast message if the device_id is not already registered. Once a response is received (assuming auto-registration is enabled) the device automatically adds the node id and mac in its table. Sender auto-registration is enabled by default and can be disabled using the following setter:
