Q: What is the data format when DTU pushes data to the cloud server?
A: 1. For single-channel serial devices, data is transparently reported. For example, if the serial port receives data as 123abcd, then the data pushed to the server is also 123abcd.
2. If it is a multi-channel device, the data format is simply adding a channel number in front of the data received from the serial port. For example, if the serial port receives data as 123abcd, then the data pushed to the server is 1#123abcd or 2#123abcd (where 1# represents RS232, 2# represents RS485). Other non-serial data reporting formats refer to the user manual appendix user protocol.
