EasyESPNow

Heavily modified ESPEasy which serves as an ESPNow sensor for RPIEasy receiver.

Generic settings can be modified in EasyEspNow-Globals.h file before compilation or it can be controlled with serial commands. Data sending works using ESPNow protocol. Only tested on ESP8266 with Arduino Core for ESP8266 v2.5.2, NONOS sDK version 2.2.2!

EasyEspNow-Globals.h settings

// This is the default name, set it if you wish (max 24 char)
#define DEFAULT_NAME        "espnowdevice"

// This is the default (send) delay time, used for DeepSleep (DeepSleep is disabled by default)
#define DEFAULT_DELAY             60

// This is the default unit number of the node, can be changed, default is 254
#define UNIT                     254

// Default destination node number (0=broadcast to every unit, set it to the RPIEasy node number for correct working)
#define DEFAULT_DESTINATION_NODE   0

// ESPNow WiFi Channel, has to be the same on ALL nodes! US:1-11, Other places on the world:1-13
#define WIFI_CHANNEL 1

// Period in milliseconds for sending alive signals to all node (default is 5minute=300.000ms)
#define ALIVE_PERIOD 300000

// Role setting possible values: (not used in ESP32 espnow)
// ESP_NOW_ROLE_CONTROLLER : only for sending (can be handy for deepsleep use-cases)
// ESP_NOW_ROLE_SLAVE      : only for receiving
// ESP_NOW_ROLE_COMBO      : capable of sending and receiving (DEFAULT!!!)  
#define ESPNOW_ROLE ESP_NOW_ROLE_COMBO

// Sketch working mode possible values:
// ESPNOW_SERIAL_GATEWAY             : serial to ESPNow bridge mode (no direct data sending or receiving)
// ESPNOW_SEND_ONLY_ENDPOINT         : only for sending (can be handy for deepsleep use-cases)
// ESPNOW_RECEIVE_ONLY_ENDPOINT      : only for receiving
// ESPNOW_SEND_AND_RECEIVE_ENDPOINT  : capable of sending and receiving (DEFAULT!!!)

#define ESPNOW_PURPOSE   ESPNOW_SEND_AND_RECEIVE_ENDPOINT

All the settings above can be managed by either by RPIEasy webGUI under http://IPADDRESS/espnow or by serial commands.
