and welcome to RIOT! I think no one used the nRF2401A. We only have (low-level) support for the nRF24L01+. Also note Nordics recommendation:
" This product is not recommended for new designs. Nordic recommends the nRF24L01+ or for a System-on-Chip solution either the Nordic nRF24LE1 or nRF24LU1+."
Why do you need the “A” version? What’s the benefit?
I didn’t find informations about “nRF120 transceiver boards”, could you provide a link? Anyway, we don’t have support for that board.
Regarding the nRF24L01+ you can find the driver here:
and a small test here: Note that it is currently just low-level support. Did you check if there is other hardware support in RIOT that might fulfil your requirements? Best, Peter
just a short note from my personal experience. Don't mix these cheap chinese modules. I got a bunch of them (PCB antenna, external antenna, black, green, ...) and in some configuration I couldn't get them to interact. Turns out those are (all?) counterfeit products that have different silicon inside. So if you run into problems, first make sure you use all the same modules in your setup.
