Supported Hardware

The following hardware has been tested and is known to work.

CrazyRadio PA USB dongle
SparkFun nRF24LU1+ breakout board
Logitech Unifying dongle (model C-U0007, Nordic Semiconductor based)

Initialize the submodule

git submodule init
git submodule update

Build the firmware

cd nrf-research-firmware
make

Flash over USB

nRF24LU1+ chips come with a factory programmed bootloader occupying the topmost 2KB of flash memory. The CrazyRadio firmware and RFStorm research firmware support USB commands to enter the Nordic bootloader.

Dongles and breakout boards can be programmed over USB if they are running one of the following firmwares:

Nordic Semiconductor Bootloader
CrazyRadio Firmware
RFStorm Research Firmware

To flash the firmware over USB:

cd nrf-research-firmware
sudo make install

Flash a Logitech Unifying dongle

The most common Unifying dongles are based on the nRF24LU1+, but some use chips from Texas Instruments. This firmware is only supported on the nRF24LU1+ variants, which have a model number of C-U0007. The flashing script will automatically detect which type of dongle is plugged in, and will only attempt to flash the nRF24LU1+ variants.

To flash the firmware over USB onto a Logitech Unifying dongle:

cd nrf-research-firmware
sudo make logitech_install

Flash a Logitech Unifying dongle back to the original firmware

Download and extract the Logitech firmware image, which will be named RQR_012_005_00028.hex or similar. Then, run the following command to flash the Logitech firmware onto the dongle:

cd nrf-research-firmware
sudo ./prog/usb-flasher/logitech-usb-restore.py [path-to-firmware.hex]

Flash over SPI using a Teensy

If your dongle or breakout board is bricked, you can alternatively program it over SPI using a Teensy.

This has only been tested with a Teensy 3.1/3.2, but is likely to work with other Arduino variants as well.

Build and Upload the Teensy Flasher

cd nrf-research-firmware/prog
platformio run --project-dir teensy-flasher --target upload

Connect the Teensy to the nRF24LU1+

Teensy	CrazyRadio PA	Sparkfun nRF24LU1+ Breakout
GND	9	GND
8	3	RESET
9	2	PROG
10	10	P0.3
11	6	P0.1
12	8	P0.2
13	4	P0.0
3.3V	5	VIN

Flash the nRF24LU1+

cd nrf-research-firmware
sudo make spi_install

continuous tone test

The nRF24LU1+ chips include a test mechanism to transmit a continuous tone, the frequency of which can be verified if you have access to an SDR. There is the potential for frequency offsets between devices to cause unexpected behavior. For instance, one of the SparkFun breakout boards that was tested had a frequency offset of ~300kHz, which caused it to receive packets on two adjacent channels.

This script will cause the transceiver to transmit a tone on the first channel that is passed in.

usage: ./nrf24-continuous-tone-test.py [-h] [-c N [N ...]] [-v] [-l]

optional arguments:
  -h, --help                          show this help message and exit
  -c N [N ...], --channels N [N ...]  RF channels
  -v, --verbose                       Enable verbose output
  -l, --lna                           Enable the LNA (for CrazyRadio PA dongles)

Transmit a continuous tone at 2405MHz

cd nrf-research-firmware
./nrf24-continuous-tone-test.py -c 5
