Itsy Bitsy NRF52 how to use radio in Arduino IDE?

by blnkjns on Wed Mar 24, 2021 2:28 pm

I want to use the radio in the Itsy Bitsy NRF52480 Express peer to peer (not BLE to phone):
https://www.adafruit.com/product/4481
I can't find any sample code for it. Anybody here who knows a starting point to get this working?
I know the chip can handle it, as it works in MakeCode for the microbit V2 (same NRF52).

@blnkjns,

We have an Arduino example using one nRF52 as a Central BLEUART and one more more nRF52 peripherals to connect to it.

Will look at that too, but it is not what I was after. I was looking to use the basic radio service, not Bluetooth.

Yeah, I missed that in your original post. I have not seen a way to use the nRF52 just a dumb radio and not as a BLE device. Have you seen any libraries that allow for this level of access? I'm just curious what terms they would use to describe this bare metal mode.

The upside of the link I did provide is it does not require a phone in the mix. At least you are still board to board communication. The downside for your scenario is it still has all the overhead of BLE.
