# 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 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 you will set the ESPNOW1 address to that of your first gateway, then you'll direct general ESP-NOW traffic to the ESPNOW1 interface:
|
|
```
|
|
#define UNIT_MAC 0x01
|
|
#define ESPNOWG_ACT sendESPNOW(0x00);
|
|
```
