OpenSteering-RS485 Data logger
Pins must be defined in rs485.h if you are using the RAK5802 you should set your pins as follows.
#define RS485_DEFAULT_DE_PIN (0xff)
#define RS485_DEFAULT_RE_PIN (0xff)
#define SERIAL_PORT_HARDWARE Serial1
To start rs485 measurements, with a single ComWinTop THC-S rs485 Soil sensor, send the following command.
2+01+03+00+00+00+03+05+CB
You can send these via MQTT downlink to the following sub
MQTT_USER/MQTT_ID/config
example: r4wk/test/config
This is all set in the mqtt_config.h
