NRF24L01 + USB SPI CONVERTER

[TotalDay]

Hello! How can i flash this NRF24L01 + USB SPI CONVERTER with ArduinoISP or SPI programmer ?

Please help!

Unfortunately it is not possible to use this firmware with an nRF24L01+ without modification. The firmware is designed to work with the nRF24LU1+, which contains a USB controller and 8051 MCU (which are not present in the nRF24L01+).

If you want to use an nRF24L01+, my recommendation would be to connect it to a 3.3v Arduino or Teensy, and modify the firmware to use the Arduino's SPI interface instead of the internal SPI interface used with the nRF24LU1+.

Marcnewlin, i read many manuals about nRF24LU1+, but i can not find specs about flash size 16 kb or 32 kb. have you any information about bootloader`s adress of this chip?

[marcnewlin]

The firmware in this repository is specific to the 32kb flash variants of the nRF24LU1+, but it should work with the 16kb variants with a slight modification.

The chips ship with the Nordic bootloader occupying the upper 2kb of flash memory. On the 32kb variants this is at address 0x7800, vs 0x3800 for the 16kb variants.

I haven't tested this with a 16kb nRF24LU1+, but it should be as simple as updating the bootloader address.

Let me know how it goes! On Jun 22, 2016 5:22 PM, "TotalDay" notifications@github.com wrote:

Today i received NRF24L01 USB adapter USB 2.4Ghz NRF24L01 UART 2.4G NRF24L01

[TotalDay]

This adapter have Chipset UART : CH340 MCU : STC11L04E VID:PID=1a86:7523

The best solution is to flash Firmware direct from USB - UART

Can someone help to flash it?

I am trying to flash via USB SERIAL CONVERTER

Changes:

static void (_nordicbootloader)() = (void ()())0x3800;

LDFLAGS = --xram-loc 0x4000 --xram-size 2048 --model-large

'USB VID:PID=1a86:7523'.lower()

dongle = usb.core.find(idVendor=0x1a86, idProduct=0x7523)

---

make install

result: device is busy

---

make spi_install

30 minutes and still nothing

I am having same problem .. -> it frozes in Writing image to flash -> i am trying to flash with teensy3.1 via SPI with cina module nrf24l01+. ... Edit: Okey problem was that i got 01+ and not LU1+. I finally underestand difference between nrf24l01+ and nRF24LU1+ :). So now i need to figure out how to change firmware to use it on 01+.

[madagaga]

Hi @SimenDeath , i have same problem. I'm not a c/asm developper but I've take a look at the "firmware" given by the seller, it handle only the nrf part. this link seems to show how to handle uart part http://www.stcmcu.com/datasheet/stc/STC-AD-PDF/STC11F-10Fxx-english.pdf

Maybe it could help

nrf part could be rewriten to handle 01/01+ as the given code is quite similar to arduino/rpi rf24 lib. Then a AT interpreter should be written to transfer command between PC <=> STC <=> nrf

I have same problem. Does anybody solve this problem?

[RoganDawes]

I haven't solved the problem, but as Marc indicated in https://github.com/BastilleResearch/mousejack/issues/19#issuecomment-227151254, the nRF24L01 has no built in CPU, which means you cannot flash firmware to it. You can consider using ucMouseJack firmware instead: (https://github.com/insecurityofthings/uC_mousejack)

This uses a separate microcontroller to drive the nRF24L01.
