nRF24L01 Wireless Serial Port TTL Serial Port to nRF24L01 Module Data Transmission Remote Control Development -71404

  TTL serial port to nRF24L01+ module realizes 2.4G wireless module SPI interface to TTL serial communication, nRF24L01+ SPI interface + STM32 microcontroller. The customer does not need to know the communication protocol of the 2.4G wireless module in detail. It only needs to know how to use the serial port to operate. The serial communication assistant can configure the wireless communication parameters through several AT commands. The system parameter setting is not lost after power-on. Keep the last state. Shorten the development cycle and quickly verify and test your own wireless communication system. The RFX2401C RF front-end amplifier chip can amplify the wireless signal to a maximum of 22dBm, effectively increasing the distance of signal communication.

• Number of valid bytes per transfer: 1-31 bytes

• Communication format with other wireless modules: bit 0 is the byte length of the transmitted data

• Open communication distance: theoretical maximum 500m (250Kbps)

Instructions

       Use USB to TTL serial board to connect this module, TX and RX cross wiring, the onboard indicator will be on after the USB is plugged in, and the indicator will flash when there is data. Install the USB to serial port driver CH340 to the computer, and open the serial port assistant to send the AT command configuration parameters.

The two modules are respectively connected to two USB to TTL serial boards, and the serial port assistant operates and observes the data transmission and communication of two 2.4G wireless modules. The default 115200 serial port baud rate

Note

• All commands are capitalized, punctuation must be half-width punctuation in English, no spaces!

• Unchangeable parameters:

• Address must be 5 digits in length

• The data length must be 32 bytes
