![]() The other logic input pins are 5V tolerant which makes things much easier. It is a 3V device and the VCC pin must not be connected to 5V. There is an on-chip voltage regulator that needs a supply voltage of between 1.9 and 3.6V on the VCC pin. The user can adjust the power of the transmission to one of four levels, (MIN, LOW, HIGH, and MAX) depending on the range required. The board contains a transceiver chip from Nordic Semiconductor, a crystal, an antenna, a few support components, and 8 connection pins. It can transmit at 250bps, 1Mbps and 2Mbps on-air rates with a choice between 125 channels (1 … 125). Nordic call it a 6 data pipe MultiCeiver because it can listen to up to 6 other devices at once and transmit to them one at a time. It has a very good range, low power consumption, is cheap to buy, readily available and has several Arduino libraries available. **********************************************************/īyte addresses =, that didn't change anything at all.This is a radio Transceiver (it both transmits and receives) which operates on the 2.4 GHz Industrial, Scientific and Medical bands. * Hardware configuration: Set up nRF24L01 radio on SPI bus plus pins 7 & 8 */ *** Set this radio as radio number 0 or 1 ***/ Users can use this sketch to troubleshoot radio module wiring etc. The printDetails output should appear as follows for radio #0: Radio configuration settings are lost - Fixed by monitoring a value that is different from the default, and re-configuring the radio if this setting reverts to the default. This is implemented internally in RF24Network. Reading from radio: Available returns true always - Fixed by adding a timeout to available functions by the user. Writing to radio: Radio unresponsive - Fixed internally by adding a timeout to the internal write functions in RF24 (failure handling) The three main failure modes of the radio include: ![]() This sketch demonstrates how to handle the various failures and Occur randomly after many hours to days or weeks. The nrf24l01+ radios are fairly reliable devices, but on breadboards etc, with inconsistent wiring, failures may This is a very basic example of how to send data from one node to anotherīut modified to include failure handling. * Getting Started example sketch for nRF24L01+ radios The code isn't the problem, since I used the same code for both and it worked fine on the official Mega. This Mega has had no problems in the past. I am trying to create a remote control system, but this problem with the off-brand Mega has me confused. If I delete the line, the radio begins spamming zeros into the Serial Monitor (what it's receiving), but only if I rest my fingers on the ICSP header (?!) This leads me to believe that radio.printDetails() is getting stuck in a loop, or crashing the Arduino, and somehow stopping the entire program. On the off-brand Mega however, the Serial Monitor says "Test" once and then nothing else. When run on the official Mega, the Serial Monitor says "Test" and then prints all the details as normal, every second. I experimentally tried the following code to set up the radio: #include However, when I run the EXACT SAME CODE with the EXACT SAME WIRING on the off-brand Mega, the program crashes / freezes at radio.printDetails(). On an official Arduino Mega, the code runs just fine, with the radio module working perfectly. ![]() I'm having an issue with a particular off-brand Arduino Mega.
