Gateway 2.000
This is the FDRS Multiprotocol Gateway sketch. The device listens for packets over ESP-NOW, UART, LoRa, and/or MQTT, then retransmits the packets over these interfaces using rules defined in the "Actions" section of the configuration file.
The most commonly used configuration tells the device to take any ESP-NOW packet it receives and output the data over the serial port (UART):
#define UNIT_MAC 0x00
#define ESPNOWG_ACT sendSerial();
The companion for this device, connected via serial, takes any data it receives from the serial port and sends it via MQTT:
#define USE_WIFI
#define SERIAL_ACT sendMQTT();
Splitting the gateway into two devices allows you to use ESP-NOW and WiFi simultaneously without channel conflicts. You can also connect the first device to a computer with a USB-UART adapter and get the data that way, eliminating WiFi altogether.
If you have sensors that are out of range of your first gateway, you can use a gateway as a repeater. First set the UNIT_MAC to 0x01, then send general ESP-NOW traffic to the address of the first gateway:
#define UNIT_MAC 0x01
#define ESPNOWG_ACT sendESPNOW(0x00);
LoRa
You can also use LoRa to expand the distances between hops. While ESP-NOW is quick enough to handle a lot of traffic in real-time, LoRa is much slower. For this reason, you must send LoRa data to a buffer and transmit it at standard intervals.
