Module data transmission wireless USB Series Support AT Command Set up the system!
Note: This price does not include NRF24L01 module! !
With a stable CH340T USB to Serial
• Two modules are power LED indicator lights (Power always) status indicator NRF24L01 (normal detection module flashes)
• Surveillance Built-in anti-collision procedures, harsh environment industrial control occasions.
• Module NRF24L01 toward the web, as shown in the figure below, insert anti-system will not work, but will not burn module
• With this module you can make the transmission distance wireless farthest range (100-1100m, depending on the use of wireless module), much higher than Bluetooth (10m) away serial transmission
Purchase program:
1.2 or more in this serial wireless module (NRF24L01 property)
Experiment The communication can be made between the module and the module can be many, many-to-many
2.1 This serial wireless module (NRF24L01 property)
You can do the experiment of communication between the computer and the microcontroller, such as single-chip wireless transmission of collected sensor data to the host computer; PC control MCU to execute multiple commands
Parameters and commands:
Note: All commands are case, the score should be half the width score in the state of English! !
1, a single byte of effective transfer: 1 -31 bytes.
The first system of 0 bytes reserved for each transmission packet size statistics; how to send serial "abc" (ASCII code 3 bytes) port, the actual transfer of "3ABC" 0 bytes on the first three, in order to receive must process to determine the actual length of the received data packet based on that number bytes.
2, Module Baud Rate: 4800,9600,14400,19200,38400,57600,115200.
Covers common transmission rate (baud rate factory default is 9600)
Baud rate modification instructions: Send ASCII code [AT + baud = x (X is 1, 2, 3, 4, 5, 6, 7 Correspondent 4800, 9600, 14400, 19200, 38400, 115200 baud rate)
Example: To change the baud rate to 115,200, then send ASCII serial debugging assistant [AT + BAUD = 7] The system responds:
Baud rate set successfully! !
Baud Rate: 115200
In this case, the baud rate is 115200, serial debugging assistant needs to change to 115200 to communicate with the module.
Note: The command must be uppercase!
3, transfer rate NRF24L01 module: 1Mbps, 2Mbps (factory default 1Mbps)
Baud rate setting command: Send ASCII code [AT + = speed x] (X is 1, 2 Corresponding 1Mbps, 2Mbps transmission rate)
Such as: Change the transfer rate of 2 Mbps, then send ASCII serial debugging assistant [AT RATE + = 2] The system responds:
The baud rate set successfully! !
Transmission power: 0dBm
Transfer rate: 2Mbps
Low noise amplification gain: open
4, NRF24L01 address configuration module: 5 address, place and address of the receiver match 0 (default 0xFF, 0xFF, 0xFF, 0xFF, 0xFF factory)
Address Set command: Send ASCII code [AT + ADD = 0x **, ** 0x, 0x **, ** 0x, 0x ** (0x ** is set to face a comma "" It must be in English half-width point )
Such as: Change address is 0x11, 0x22, 0x33, 0x44, 0x55, then send ASCII serial debugging assistant [AT + ADD = 0x11, 0x22, 0x33, 0x44, 0x55] The system responds:
Defining Success Address! !
Location Address: 0x11, 0x22, 0x33, 0x44, 0x55
Get endpoint address 00:00 x11, 0x22, 0x33, 0x44, 0x55
5 Survey Information System:
Query command: Send ASCII code [? AT] The system responds:
AT?
Information about the system:
Baud Rate: 115200
Location Address: 0x11, 0x22, 0x33, 0x44, 0x55
Get endpoint address 00:00 x11, 0x22, 0x33, 0x44, 0x55
Transmission power: 0dBm
Transfer rate: 2Mbps
Low noise amplification gain: open
