nRF905 connection with nRF51DK

[Rajneesh]

Hello All,

How to interface nRF905 with nRF51DK board? Any driver is available for nRF905 which support nRF51.

Any help will be appreciated.

Regards, Rajneesh

Hi,

Do you mean by using radio or connecting the chips together by wire?

If you mean radio, the nRF905 uses the ShockBurst protocol at the 868/905 MHz or 468 MHz ISM bands, the physical hardware is in other words not compatible with the radio on nRF51 which is operating in the 2.4 GHz ISM band.

Connecting them via wire is pretty straight forward, you connect the nRF51 to the nRF905 using SPI, and follow the documentation to send data over the bus. Unfortunately we do not have a ready example for this.

Best regards,

Øyvind

Thanks for reply,

please give coding reference for implementing nRF905 on nRF51 board.

Hi,

You can take a look at the SDK examples for using SPI, also have a look a the documentation chapter 26 and 27.
