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

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.

Hi

What kind of hardware are you using on the nRF24L01+ side? Just a regular Arduino Uno?

Have you been able to verify the Arduino/nRF24L01+ kit in isolation by using a similar kit as the receiver, or could there be issues on the Arduino side as well?

Best regards
