The module supports basic AT Commands: Baudrate, Parity bit, ID Number, Version Information, Transmit Power, Frequency Band, Acknowledge Mode and other function settings and queries.
When the module is in AT Mode, the user can use the serial port to send AT Commands to set the parameters of the module.
When the module is in transparent data transmission mode, in ACK mode (default), it can be used as a one-to-one transceiver. If it is applied to one-transmit and multiple-receive (master-slave mode), it needs to be changed to NO-ACK mode through AT command
When the CMD port of the AT module is short-circuited, it enters the AT mode. and when it is disconnected, it is the data transparent transmission mode.
When the module is abnormal, short-circuit the two pins of RES on the board for 5 seconds, then power on again to restore the factory settings
Frequency range: 2400~2525MHz
Transmission power: 11dBm;
Receiver sensitivity: -84dBm@1MHz;
Working temperature: -40~+85℃;
Baud rate: 1200, 2400, 4800, 9600 (Default), 19200, 38400, 57600, 115200
Open-field transmission distance with sufficient power supply: 80-100 meters
Size: 33 x 15 x 3mm
Weight:2.5g
Pinout :
2 GND: power ground
3 RXD: TTL RXD data
4 TXD : TTL TXD data
5 CMD: AT mode switch port
6 RES: Factory reset port
Note: After the two ports of RES are shorted for 5 seconds, the module will restore the factory settings and restart automatically.
The transmit current is 50mA (+11dBm); the receive current is 25mA, please use a small ripple power supply
Note: In order to make the module work stably, it is recommended to use a power supply above 8W (5V/2A , 6V/2A, 7.4V/1.5A, 9V/1A, 12V/1A)
AT command:
Please refer to the AT command manual below
