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.
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
The ESB library in the nRF5 SDK v12.2.0 is designed to be backwards compatible with the nRF24L01/nRF24L01+, assuming you don't use the L01 device in legacy Shockburst mode (ACK's disabled).
On the nRF5 side you can use the esb_ptx and esb_prx examples as a starting point: \nRF5_SDK_12.2.0\examples\proprietary_rf\
For this to work you need the following settings on the nRF24L01 side:
Default address (0xE7E7E7E7E7), with 5 byte address length
16-bit CRC
2Mbps bitrate
Auto ACK and dynamic payload length enabled
For all other settings you can use the default values.
Edit: Added attachment.
Best regards

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,
