default value is 001, a nd the working frequency is 433.4MHz. The channel stepping is

400KHz, and the working frequency of Channel 100 is 473.0MHz.

Example:

Send "AT+C021" to module to set module channel to be 021 working frequency is

441.4MHz

Return: "COK+C021"

A s the wireless receiving sensitivity of module is relatively high, when the serial port

Note:

baud rate is greater than 9600bps, five adjacent channels shall be staggered to use. When the

serial port baud rate is not greater than 9600bps, in short-distance (within 10m)

communication, again, five adjacent channels shall be staggered to use.

4. AT+FUx

Set module to wireless UART function. The value of x is optional within 1~ 3. The default

mode of module is FU3, and only when serial port function mode of two modules is set to be

the same the communication can be realized.

F means function, and U means UART

Example:

Send "AT+FU1" to module configuring module to be come UART FU1.

Return: "AT+OK"

5. AT+Px

Set transmitting power of module, x is optional from 1 to 8, and the corresponding

transmitting power of module is as shown below:

x value

Transmitting power of module (dBm)

The default value is 8, and the higher the transmitting power is, the farther the

communication distance is. When the transmitting power level is set to be 1, the transmitting

power is the minimum. everytime the transmitting power is reduced by 6dB,the

communication distance will be reduced by half.

Example:

Send "AT+P5" to module configuring the transmitting power to level 5 which is 11dBm.
