Abstract
I buyed this Modul because I tried different Communication Systems. In this Post I try to collect the informations about it, because documentation is very low.
Parameters and commands:
1. The number of bytes in a single transmission valid: 1-31 bytes.
The first 0 byte system reserved for each transmitted packet length statistics; for example serial port to send "123" (ASCII code, 3 bytes), the actual transfer when the first byte 0 to 3, the receiving end of the actual should be handled to determine the packet length byte received under this number.
2. Module Baud Rate: 4800,9600,14400,19200,38400,57600,115200.
Covers common baud rate, (factory default 9600)
Baud rate modification command: send ASCII code [AT + BAUD = x] (x is 1,2,3,4,5,6,7 4800,9600,14400,19200,38400,57600,115200 the corresponding baud)
Such as: Modify the baud rate to 115200, the serial debugging assistant sending ASCII [AT + BAUD = 7], the system replies:
Baud rate setting success !!
Baud Rate: 115200
At this baud rate of 115200, serial debugging assistant need to switch to 115 200 to communicate with the module.
Note: The command must be in uppercase letters!
3.NRF24L01 module transmission rate: 1Mbps, 2Mbps (factory default 1Mbps)
Transmission rate setting command: send ASCII code [AT + RATE = x] (x 1,2 respectively 1Mbps, the transmission rate of 2Mbps)
Such as: modify the transmission rate of 2Mbps, then sending ASCII serial debugging assistant [AT + RATE = 2], the system replies:
Transmission rate setting success !!
Transmit power: 0dBm
Transfer rate: 2Mbps
Low-noise amplifier gain: open
4, NRF24L01 module address setting: 5 address, local address and the receiver address matches 0 (factory default 0xFF, 0xFF, 0xFF, 0xFF, 0xFF)
Address Set command: Send ASCII code [AT + ADD = 0x ??, 0x ??, 0x ??, 0x ??, 0x ??] (0x ?? address you want to set a comma, the comma must be in English half-width )
Such as: change the address for 0x11,0x22,0x33,0x44,0x55, then sending ASCII serial debugging assistant [AT + ADD = 0x11,0x22,0x33,0x44,0x55], the system replies:
Address Setting Success !!
Local Address: 0x11,0x22,0x33,0x44,0x55
Receiving end address 0: 0x11,0x22,0x33,0x44,0x55
5, System Information inquiry:
Query: sending ASCII [AT?], The system replies:
AT?
System Information:
Baud Rate: 115200
Local Address: 0x11,0x22,0x33,0x44,0x55
Receiving end address 0: 0x11,0x22,0x33,0x44,0x55
Transmit power: 0dBm
Transfer rate: 2Mbps
Low-noise amplifier gain: open
