5.4.2.1 Fixed-point transmission example
Module 0x0003 sends "30313233343536373839" hex data to module 0x0001
Tx end 0D C2 00 03 30 31 32 33 34 35 36 37 38 39
Rx end 0F 42 00 01 00 03 30 31 32 33 34 35 36 37 38 39
5.4.2.2 Broadcast example
The device 0x0003 broadcasts the data "30313233343536373839". Other modules in the network receive broadcasts. Take
module 0x0001 and module 0x0005 as examples.
Tx end 0D C2 ff ff 30 31 32 33 34 35 36 37 38 39

Remark
1. Check digit parameters are consistent with 3.1.25 check digit setting configuration parameters;
2. The data bit parameters are consistent with the 3.1.21 setting uart data bit configuration parameters;
3. The stop bit parameters are consistent with 3.1.23 setting uart stop bit configuration parameters;
4. The baud rate parameter is consistent with the 3.1.11 baud rate setting configuration parameter
5. The restart function is to restart after configuration. 1 means restart, 0 means no restart.
6. Transparent transmission enable indicates that transparent transmission is enabled and prohibited. 1 is enabled, 0 is
disabled.
7. Any node can initiate air configuration.
8. Among them, the UART configuration restart takes effect and is saved after power-off;
9. Restart and transparent transmission enable will take effect immediately, save after power off.
Note:
After configured for transparent transmission, uart will no longer receive configuration parameters. If you need to set the
module through uart, you need to cancel the transparent transmission enable through the air configuration, or use the
restart pin to restart the parameters.
