Hello everyone,
I have RAK7431 Modbus-LoRa bridge wired with T9501 temperature and humidity sensor from Telaire, and have following configuration of RAK7431:
AT+REGION=EU868
AT+JOINMODE=OTAA
AT+CLASS=C
AT+APPEUI=xxxxxxxxxxxxxxxxxx
AT+APPKEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
AT+CONFIRM=0
AT+BAUDRATE=115200
AT+DATABIT=8
AT+PARITY=NONE
AT+STOPBIT=1
AT+DTUMODE=MODBUS
AT+MODBUSTIMEOUT=1000
AT+TRANSPARENT=0
AT+MODBUSRETRY=1
AT+POLLPERIOD=60
AT+ENABLEPOLL=1
I used this document to enable polling every 60 seconds.
According to sensors datasheet, after all commands from the above I tried with this command:
AT+ADDPOLL=1:100413890001E7E5 to read the Firmware Revision
But I can not even see any SYSLOG4:DTU Tx log on my console, like modbus is not working at all.
Can you please provide some guidance where to start, or where I am making mistake?
Thanks alll!
