How to Write Basic Library for NRF24L01 PART2 || Transmit DATA || SPI STM32

[@VarunVh2014]

Thanks. But a 🪲in Code downloaded. Check your nrf transmit function where config register is setup. Change " config=config&(0xF2) " . This will always make config=0x00 because intialy config is set to 0x00. And your transmitter will never work. Struggled a little to find this.

So what value should be right now? I have problem with this too

your comment should be pinned. Thanks for all the hardwork to find the bug🤣. I suppose that will be done for Wifi receive signal

Nice, thank you people!

I got it working. Verified. Thank you so much for this tutorial

[@lukasz-bis]

I was having a trouble to get this to work but figured it out already, here are some tips to make the "Trasmit" part working correctly: - in function NRF24_TxMode() -> comment this: "config = config & (0xF2);" -> uncomment this: "config = config | (1

You are the best. Thanks a lot

Thanks a lot for the tutorial videos, i am new to stm 32 and your videos greatly helped me. I an trying to send data from stm32f411 to arduino uno using nrf24 module. not able to get this working any hints on what could be the issue. I dont receive any data. i am suing RF24 library for arduino uno.

did you solve

@@alidemir8434 same problem, did you solve?

[@NollsteadStudio]

@@domm179 and @VishalJN I know your question is old and maybe you solved it by now but I had the same problem. In my case I added radio.setCRCLength(RF24_CRC_DISABLED); to my Arduino code (since his example doesn't use CRC) and it started working. Changing the CRC length isn't something that is in most Arduino examples so I wouldn't think most people ever used that function (I know I didn't). Hope this helps either you or anyone else trying this with the same problem.

Hello, When I read fifostatus , I just take 0x00 so it doesnt tell me that Tx fifo is full. But I send 32 bytes. Can someone explain me reason ? I m observing spi bus with logic analyzer. I see all setups are done properly. I see the datas which I send. Just problem is on fifostatus value. Thanks in advance

[@askinc102]

I am facing the same issue. I got the FIFO status as 33 '!'. Did you find a fix?

[@CaliBeta]

Excellent explanation helped me a lot, but I am having a problem with data transmission, when I use a logic analyzer to record the data on the SPI bus, the command to read the state of the FIFO STATUS always gives me two possible values: 0x01 in the first transmission, that is, FIFO RX empty, Data in FIFO TX. After the third transmission attempt, the FIFO TX buffer fills up completely and it responds with a 0x21, FIFO TX full, FIFO RX empty This means that the NRF24L01 + never sends the data and it always stays in the FIFO TX. I have no idea how to solve this problem 😒

same here

did you solve the problem ?

[@FembeliX]

Hello everyone, I run into the same issue. Did anyone managed to fixed that and found the reason?

[@FembeliX]

I have found someone who figured out, the problem accoures because of SPI/CS timing problems. Adding a delay in NRF24_Transmit (uint8_t *data) just before CS_UnSelect(); did not work for me.

Check out the comment from Varun for solving the FIFO issue

How do I make my code sheet colorful like yours?

[@miguelramirez-ie6ij]

hello dear friend , your videos are awesome but im facing a debugg issue , is related to the fifostatus variable: Failed to execute MI command: -var-create - * fifostatus Error message from debugger back end: -var-create: unable to create variable object i hope you are well , saludos desde mexico

[@miguelramirez-ie6ij]

im already solve the Tx module :)
