How to integrate zigbee Wireless Communication Module with Arduino
This article mainly shows you "Arduino how to integrate zigbee wireless communication module", the content is easy to understand, clear, hope to help you solve doubts, the following let the editor lead you to study and learn "how Arduino integrates zigbee wireless communication module" this article.
1. Hardware inventory:
Arduino 101one
Dfrobot IO sensor expansion board V7.1
Zigbee module (Shenlian Innovation DL-LN33) two pieces
CP2102 module USB to TTL one
One LED lamp.
Some DuPont lines
two。 Experimental purpose:
Use arduino 101to connect the zigbee module through the serial port (pin0-1 Magi RX Murtx). Arduino uses the usb serial port line and PC connection, which is used as the A terminal. The other end is B, which uses the CP2102 module to connect the zigbee module directly to the PC. FE 0591 9053 0D 01 FF is sent on the B-side PC using LN33's own serial port debugging tool. The A-side zigbee module receives the signal and transmits the data to the arduino through the serial port, triggers the LED light on the arduino to flicker, and then outputs the received data to the USB serial port.
