What’s different here from the previous example is that we need to create two pipes or addresses for the bi-directional communication. write(&buttonState, sizeof(buttonState)) Radio.openReadingPipe( 1, addresses) // 00002 Radio.openWritingPipe(addresses) // 00001 */ # include # include # include # include # define button 4 RF24 radio ( 7, 8) // CE, CSN const byte addresses = ![]() * Arduino Wireless Communication Tutorial 3V, SDA, and SCL) on your Arduino Nano to four SparkFun Qwiic connectors. Here are the two codes for the wireless communication and below is the description of them. With an on-board DB9 and CAN-BUS connector you can choose a suitable port. #Canbus to arduino nano pinout install#Just search for “rf24” and find and install the one by “TMRh20, Avamander”. We can also install this library directly from the Arduino IDE Library Manager. #Canbus to arduino nano pinout download#Once we connect the NRF24L01 modules to the Arduino boards we are ready to make the codes for both the transmitter and the receiver.įirst we need to download and install the RF24 library which makes the programming less difficult.
