Trying to connect RAK7431 to an electrical submeter with a Modbus RS485 connection. The meter has over 500 Modbus registers, but the RAK7431 polling instruction limits the register polling from 1-127. How do I poll higher Modbus registers with the RAK7431? For example poll the following registers 1199, 1207, 1143, 1145, 1147, 1151, 1153, and 1155 with the RAK7431?
This attribute which can get value from 1 to 127 (N) is about the ID of the poll that you create.
The next attribute marked with “XXXX” is the polling instruction content, which includes the registered address that you want to read/write. So there you can write whatever address you want.
