One: function introduction
1,USBWireless serial port data transmission module, supportATCommand to configure the system!
2StableCH340TdoUSBSerial port
3Built-in watchdog anti-crash program can be used in harsh industrial control applications.
4,NRF24L01The insertion direction of the module is shown in the picture below. The plug-in system will not work but it will not burn out the module.
5Using this module as a wireless serial port can make the transmission distance farther(100~1100m,Depending on the wireless module used), far higher than Bluetooth(10m)Serial transmission distance
Two: parameters and commands:
1One-time transfer of valid bytes:1-31byte.
The first0The byte system is reserved for packet length statistics for each transmission; for example, the serial port sends "123"(ASCIIcode,3Bytes), actual transfer time0The bytes are3When receiving the actual processing, the length of the received data packet should be determined according to the number in this byte.
2Module baud rate:4800,9600,14400,19200,38400,57600,115200.
Covers common baud rates,(Factory default baud rate9600)
Baud rate modification instruction: sendASCIIcode【AT+BAUD=x】(xfor1,2,3,4,5,6,7Correspondence4800,9600,14400,19200,38400,115200Baud rate)
Such as: modify the baud rate115200, the serial debugging assistant sendsASCIIcode【AT+BAUD=7], System reply:
Communication baud rate is set successfully!!
Baud rate:115200
Baud rate at this time115200, Serial debugging assistant needs to switch to115200Can communicate with the module.
Note: The command letters must be capitalized!
3,NRF24L01Module transmission rate:1Mbps,2Mbps (Factory default1Mbps)
Transmission rate setting command:sendASCIIcode【AT+RATE=x】(xfor1,2Correspondence1Mbps, 2MbpsTransmission rate
For example: modify the transmission rate to2Mbps, the serial debugging assistant sendsASCIIcode【AT+RATE=2], System reply:
Transmission rate is set successfully!!
Transmission power:0dBm
Transmission rate:2Mbps
Low Noise Amplifier Gain: On
4,NRF24L01Module address setting:5Bit address, local address and receiver0Consistent address(Factory default0xFF, 0xFF, 0xFF, 0xFF, 0xFF)
Address setting command: SendASCIIcode【AT+ADD=0x??, 0x??, 0x??, 0x??, 0x??】(0x??For the address to be setcomma,Must be a comma in English)
Such as: modify the address to0x11, 0x22, 0x33, 0x44,0x55, the serial debugging assistant sendsASCIIcode【AT+ADD=0x11, 0x22, 0x33, 0x44,0x55], System reply:
The address is set successfully!!
Local address:0x11, 0x22, 0x33, 0x44,0x55
Receiver address0:0x11, 0x22, 0x33, 0x44,0x55
5, system information query:
Query command: sendASCIIcode【AT?】,System reply:
AT?
system message:
Baud rate:115200
Local address:0x11, 0x22, 0x33, 0x44,0x55
Receiver address0:0x11, 0x22, 0x33, 0x44,0x55
Transmission power:0dBm
Transmission rate:2Mbps
Low Noise Amplifier Gain: On
