How to Write Basic Library for NRF24L01 PART 3 || Receive DATA || SPI STM32

[@vishnusankarankutty7077]

Thank you so much sir , this was really helpful . Like NRF , most of us are facing difficulty in understanding LoRa modules and their libraries. So it will be really helpful if you could post a similar dedicated series for LoRa.

[@edvinass3804]

Hey guys, if its not working for you, you can try to check the spi settings, the boud rate must be the same for Rx and Tx and check the data size, make it the same for both TX and RX equal to 8 bits. It worked for me, a noob mistake, but im happy it works now, good luck!

[@nguyen-vt8zy]

How did you fix the error?

[@manoftheday1]

Thank you so much sir, please get more modules sir for you to be able to complete the other functions of the module, God will provide for you thanks.

[@ashas2090]

It was a helpful set of sessions. Can you please explain how to handle Interrupts as well.?

[@willson8246]

Reall good videos for all 3 parts.

[@Zelan666]

Thank you for your videos! I have setted up the transmitter part of the project (data is sended, led is blinking 1 hz), but i cant receive any data on the receiver side. The ststus register is allways 0xE - all pipes are empty. What can be the problem?

[@Zelan666]

I have solved my problem. In NRF24_RxMode i configured pipe 0 (instead of pipe 1) and then made changes in function uint8_t isDataAvailable (int pipenum) - if ((status&(1

[@WBrianez90]

@@Zelan666 i have this issue but changing pipe nums still the same "0x0e error"... so i have the TX sending messages OK but the RX does not receive yet (i already test my both modules as TX and both works)

[@narasimmanm1500]

Awsome Explanation...Thank you so much sir, this was very useful. this same NRF Module(in build antenna) with obstacle and without obstacle how much range it will cover.

[@marcinn3668]

I can't grasp the bit at @5.50. The code checks if status&(pipeline

[@ControllersTech]

You have to individually read it. Let's say you have received data in P1, P3 and P5. You have to first check the status with P1, then write 1 in the RX_DR to clear it. Since the data is available in 2 more pipes, it will again set to 1. You repeat this process until all the reads are done. Check the last point ('c') on page 59 of the datasheet

[@DucNguyen-rr2ug]

@@ControllersTech little bit late here, my question is what if the data occur on pipe 3, we still get 1 from the function isDataAvailable, isnt that a fault

[@electrobrains]

can you make a video with nrf and multiple joystick control,please

[@michaczajka3854]

Yeah! Thats what im working on right now, some help would be cool.

[@bandamsuryaprakash7782]

Thank you so much sir, this was very useful. Can you make a similar video for a mems sensor(gyroscope,accelerometer,magnetometer) in a similar manner.

[@ControllersTech]

There already are videos covering adxl345 and mpu6050

[@urichaplin1424]

I tried to use this code to transmit to USB-NRF24L01 module from AliExpress and it not work. Can you correct it for standard protocol ?

[@nguyen-vt8zy]

​@ControllersTech I don't know why I don't satisfy the condition if( isDataAvailable(1) == 1) and the value STATUS register is 0

[@miguelramirez-ie6ij]

Hi @ControllersTech I'm facing a problem with the Receiver module , when I'm debug always run into the void error_handler (in the main.c) , I don't know why could you please help me with some Tip , Good vibes from Mexico!! PD: you are awesome bro , I recommend always all your videos in my university

[@minhnhutnguyen1942]

Thank you so much . but i have a problem , how address esbtalish for pipe 2 and pipe 3 to receive data. in function RxMode

[@binztran3249]

What is the current on your transmitter module? The current on my transmitter module is about 100uA, the receiver module is 15mA. Right or wrong? LED on my transmitter does not blink. Plz help

[@VarunVh2014]

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 🪲.

[@nguyen-vt8zy]

@@VarunVh2014 My receiver don't active, please help me

[@dhruvsharma6031]

sir why you did set channel no. 10 in rx mode Please reply

[@ControllersTech]

So that we can receive data, which the transmitter is sending on channel 10

[@dhruvsharma6031]

@@ControllersTech can i use arduino as receiver and stm32 discovery as transmitter

[@ControllersTech]

How does that matter ? You are using NRF for communication. As long as the channel and baud rate are same, you can use whatever you want.

[@dhruvsharma6031]

But sir arduino use char data type as receiving data type and we are using uint8_t data type as sending data type i think that's why arduino doesn't receive anything but garbage data.

[@ControllersTech]

1. I don't care about Arduino. You ask the person, whose library you are using. 2. Data is transmitted as ascii. So you should manage it accordingly. 3. Check tha baud rates and other setup, like acknowledgement and data length etc..

[@nguyen-vt8zy]

receiver donnot active

[@OnyekaChukwu-k4u]

My RECEIVE isn't working, Any help???

[@vocvachchannel5191]

turn on config = config | (1

[@faramirchevlonski6152]

How can I do to fit this library in an Arduino Architecture?

[@ControllersTech]

The process remains same. You need to change how to read and write SPI bus using arduino.
