Data Transparent Mode
When the RS485 data interface works in Modbus mode, the data encapsulation format can be divided into two
types: transparent mode and non-transparent mode.
In transparent mode, the Modbus execution instruction response data (data, received by the node) will be
directly forwarded through the LoRaWAN network.
In the non-transparent mode, the Modbus execution instruction response data (data, received by the node)
will be encapsulated in the message header according to the Modbus protocol, and then transmitted to the
server through LoRaWAN.
NOTE
The non-transparent mode is the default one.
Enter the following AT command in the RAK Serial Tool to change the mode:
AT+TRANSPARENT=n
