want nrf24l01 communication with nrf51822

[pallavi]

hello,will you please tell me which code i have to use in the sdk 12.2.0 for rf communication with nrf51822 and nrf24l01 .and also tell me which settings i have to do for nrf24l01 side as a transmitter.so that i can receive data on nrf51822 side.

Hi Pallavi

You should be able to find the project here
Please note that it has only been tested on the nRF52DK. I only confirmed that it compiled on the nRF51DK, but didn't have time to test it.
The pins used for the nRF24L01+ module is 11, 12, 13, 14, 15, 16, which corresponds to CE, CSN, SCK, MOSI, MISO, IRQ (in that order).

Best regards

hello sir, thank you for the code but i am not getting how can i use this code for the rf communication. on one side i am using the arduio with nrf24l01 through SPI.and i am looking for the code on arduino platform so that i can easily communicate with nrf51.the code here you had given on keil platform.thats why i am confused now.i am not getting what can i do now.but thank you for your code.

Hi Pallavi
You can use the attached code to verify that the nRF24L01 module is working correctly, and is able to communicate with your nRF51 kit (you just need a separate nRF51 kit to run the nRF24L01).
You can also use it to compare the register values and the control signals for the nRF24L01 module, and see how they differ from your Arduino implementation.
With that information in place it would hopefully be easier for you to see what is wrong on the Arduino side (assuming of course your L01 module works fine).
Since I don't have your hardware I can't really test that on my side.

Best regards

sir, i at one point i am succesful for achieving communication between nrf51822 and nrf24l01.but there is one problem i am facing now i am receiving interrupt from nrf24l01 but at the receiver end i am not getting any data. for which i had used the code from sdk 12.2.0 from the folder examples/peripherals/radio in this code the settings given for nrf24 series, these are as follows, uint8_t tx_address[5] = { 0xC0, 0x01, 0x23, 0x45, 0x67 };

• hal_nrf_set_rf_channel(7);
• hal_nrf_set_address_width(HAL_NRF_AW_5BYTES);
• hal_nrf_set_address(HAL_NRF_TX, tx_address);
• hal_nrf_set_address(HAL_NRF_PIPE0, tx_address);
• hal_nrf_open_pipe(0, false);
• hal_nrf_set_datarate(HAL_NRF_1MBPS);
• hal_nrf_set_crc_mode(HAL_NRF_CRC_16BIT);
• hal_nrf_setup_dynamic_payload(0xFF);
• hal_nrf_enable_dynamic_payload(false);
• @endverbatim
• When transmitting packets with hal_nrf_write_tx_payload(const uint8_t *tx_pload, uint8_t length),
• match the length with PACKET_STATIC_LENGTH.
• hal_nrf_write_tx_payload(payload, PACKET_STATIC_LENGTH); according to this i had programmed arduino board with the following settings, const byte rxAddr[5]={0xC0,0x01,0x23,0x45,0x67}; radio.setDataRate(RF24_1MBPS); radio.setChannel(7); // radio.setRetries(15,15); radio.setCRCLength(RF24_CRC_16); radio.openWritingPipe(rxAddr); radio.stopListening(); and for the payload length making equal i had chaned the arduino library function and made payload width 1. at one point i had received the data from nrf24l01.but when next time i started to code arduino board and nrf51822 my rf communuication fail.i dont know how this happened. will you please help me in one thing because now i am thinking reversly i am trying to change opayload width of nrf51822 .will you please help me how to change the payload width with 32 bytes.cz nrf24l01 has default payload width of 32 bytes. so please tell me what changes i have to do for changing payload widgth of nrf51822 according to receing 32 bytes data.

hello sir, i have compiled your code in C:\nRF5_SDK_12.2.0_f012efa\examples\proprietary_rf\l01_test_app\esb_ptx\pca10028\blank\arm5_no_packs folder but it is showing errors.and you told that you have compiled this code in the nrf51 DK.but in my case it is not getting compiled.will you please tell me the path i have followed to locate this code right or wrong.if wrong path then may be it is showing that errors the errors are as,
