Use of frequency hopping on Nordic transceiver

[Robin]

Hello, I am looking into the possibilities of implementing frequency hopping using the nRF24L01+ radio with an external Ti MSP430 microcontroller. I have read that it's predecessor radio, the nRF24L01, is capable of frequency hopping: "Short switching time enable frequency hopping", Source: data.mecheng.adelaide.edu.au/.../nRF24L01_prelim_prod_spec_1_2.pdf So I can imagine the superior + version is able to this as well.

Could someone inform me on how frequency hopping can be implemented with this setup and where I could start? I am aware this has to be done in the software on the microcontroller, but I'm not having any luck in finding a useful frequency hopping software scheme.

Thank you in advance.

Hi, Robin, assuming I understand your definition of frequency hopping to be sequentially switching channels in an agreed manner between PTX and PRX, this seems trivial to do with the + version. All one needs to do is set the RF_CH register according to the desired channel. As long as the channels on each end are the same, you'll get a connection (assuming the other non-frequency related configurations and features are set properly).
