3.3.4 Compose the uplink payload
Through AT+COMMANDx and AT+DATACUTx we got valid value from each RS485 commands,
Assume these valid value are RETURN1, RETURN2, .., to RETURNx. The next step is how to
compose the LoRa Uplink Payload by these RETURNs. The command is AT+DATAUP.
Examples: AT+DATAUP=0
Compose the uplink payload with value returns in sequence and send with A SIGNLE UPLINK.
Final Payload is
PAYVER + VALID Value from RETURN1 + Valid Value from RETURN2
+ … + RETURNx
Where PAYVER is defined by AT+PAYVER, below is an example screen shot.
