Radio communication (Nordic Gazell)

Post by jarda » Tue Jan 08, 2019 12:40 am

Is there something new in radio communication between microbit and the other microcontroller world? Is there any possible (not obscure) way to communicate with china's NRF24L01 or something else cheaper than microbit itself?

In theory, the "radio" module uses exactly the same protocol as NRF24 does, and it should be possible to have them communicate out of the box. In practice, I've spent several weeks trying to get that working, and failed — I only managed to receive about 1 in 1000 packets on the NRF24 side, and mangled. I'm not sure if that is because some inherent difference in the protocol or the modulation that I didn't catch from the docs, or simply because I was using cheap Chinese clones that could be inaccurately tuned, but without being able to actually see the signal with some kind of SDR I couldn't think of a way to debug this, and ultimately I gave up.
