Setting
| Commands | Commands + Data | Example | note |
|---|---|---|---|
| Set operation frequency | A7,7A + 00 | send A7 7A 06, the channel will be set to 6 | Channel value from 0×00~0xEE, 238 channels in total |
| Set baud rate | A3, 3A + 01 | send A3 3A 03 set the baud rate to 19200 | 01：4800, 02：9600, 03：19200 |
| Set operation power | AB,BA + 00 | send AB BA 0A, set the operation transmission power to 10dBM | Transmission power can be 0、5、7、10dBM |
| Set module ID | A9, 9A + 00 09 | send A9 9A 00 08, set the module ID to 8, this ID are stored in EEPROM | If the ID need to be converted into hex first |
| Read module specification | A6, 6A | send A6, 6A, return A6 00 64 02 0A 00 00 = The initial code returned, Operation channels, Data speed 100Kbps, 02 Means the baud rate is 9600, Transmission Power is 10dBm, Module ID |
- Default settings, Operation channel = 0, Data speed = 100kbps, Baud rate = 9600, Transmission Power = 10mW, Module ID = 00 00
- Note: Send only less than 30 bytes data each time, otherwise it will not succeed
