The transceiver module consists of a fully integrated frequency synthesizer, a crystal oscillator, an amplifier, a demodulator, a modulator, and an Enhanced ShockBurst protocol engine. Current(Standby Mode) 26♚ Logic Inputs 5V Tolerant Communication Range 800+ m (line of sight) Output Power 0 dBm Operating Supply Voltage 1.9 V to 3.6 V Max. NRF24l01 Module Specifications: Frequency Range 2.4 GHz ISM Band Maximum Air Data Rate 2 Mb/s Modulation Format GFSK Max. NOTE: Don’t connect the VCC pin directly to the 5V pin of Arduino. It is usually marked by enclosing the pin in a square so it can be used to identify the other pins. 7 CE (Chip Enable) It is the enable pin of the module it is used to select the mode of the nRF24L01 which are either transmit or receive, depending upon which mode it is currently in. It is used to send data to the microcontroller 6 SCK (Serial Clock) It accepts clock pulses provided by the SPI bus master. 5 MISO (Master In Slave Out) It is SPI output from the nRF24L01. It is used to receive data from the microcontroller 4 IRQ It is an interrupt pin that alerts the master when new data is available to process. 3 MOSI (Master Out Slave In) It is SPI input to the nRF24L01. We need to keep this pin high except when we are sending the device an SPI command or receiving data on the SPI bus from the micro-controller. 2 CSN (Chip Select Not) It is an active-LOW pin and is normally kept HIGH. So, we can connect it directly to the 3.3V output of our Arduino. Pin Name Pin Specifications 1 VCC This pin is used to supply power to the module. NRF24L01 pinout and specifications are given below. Its maximum range is up to 100 meters if used in an open space with an antenna. Power consumption of the module is very low, only 9.0mA at an output power of -6dBm and 12.3mA in RX mode which is even less than a LED. Transceiver means the same module can be used as a transmitter or receiver.

#ARDUINO MEGA RF24 PINOUT SERIAL#

When i open up the serial monitor, it spits out values a few times a second that are mostly 0 but sometimes are a random number, sometimes a long one, sometimes negative, but mostly it just returns 0.NRF24L01 is a single-chip radio transceiver that uses the 2.4 – 2.5 GHz ISM band world-wide. I even swapped a different physical nrf and breakout board, still the same issue. I still have no idea what im doing wrong. I tried moving the CS pin to 53, no luck.

#ARDUINO MEGA RF24 PINOUT CODE#

*-( Declare User-written Functions )-*/Īllright, this is the code im using for the reciever.

DO something with the data, like print it MyRadio.read( &dataReceived, sizeof(dataReceived) ) // Get the data payload (You must have defined that already!) While (myRadio.available()) // While there is data ready If ( myRadio.available()) // Check for incoming data from transmitter MyRadio.openReadingPipe(1, addresses) // Use the first entry in array 'addresses' (Only 1 right now) tPALevel(RF24_PA_MAX) // Uncomment for more power

getting_started sketch, and the likelihood of close proximity of the devices. Set the PA Level low to prevent power supply related issues since this is a tChannel(108) // Above most Wifi Channels

Serial.println(F('Questions: // Start up the physical nRF24L01 Radio Serial.println(F('RF24/Simple Receive data Test')) Use the serial Monitor (Symbol on far right). Int dataReceived // Data that will be received from the transmitter RF24 myRadio (53, 48) // 'myRadio' is the identifier you will use in following methodsīyte addresses = // Create address for 1 pipe. (Create an instance of a radio, specifying the CE and CS pins. *-( Declare Constants and Pin Numbers )-*/
