|#define ESP_NOW_KEY (NULL)|
Key used for the communication between ESP-NOW nodesThe key has to be defined to enable encrypted communication between ESP-NOW nodes.
The key has to be of type uint8_t  and has to be exactly 16 bytes long. If the key is NULL (the default) communication is not encrypted.
Please note: If encrypted communication is used, a maximum of 6 nodes can communicate with each other, while in unencrypted mode, up to 20 nodes can communicate.
