RE: RUST for Nordic nRF 52

Hi Andre,

If you want to go with a pure-Rust solution, the best starting point is nrf-hal: https://github.com/nrf-rs/nrf-hal

It's not well documented, unfortunately, so I suggest you read up on the general documentation about embedded Rust, if you haven't already: https://docs.rust-embedded.org/

If you want to target Nordic's SDK from Rust, there's nrf52dk-sys, but I've never used that and don't know what its status is: https://github.com/jamesmunns/nrf52dk-sys

I haven't worked with Bluetooth yet, so I don't know what works best here. But here are some things I'm aware of:

If you're just playing around and don't need qualification, there's Rubble, a pure-Rust BLE stack for nRF52: https://github.com/jonas-schievink/rubble
There are Rust bindings for Zephyr: https://github.com/tylerwhall/zephyr-rust

If you need help with anything the nRF Rust channel on Matrix is probably a good place: https://matrix.to/#/#nrf-rs:matrix.org

All the best,
Hanno

nRF52 uses a Cortex-M4 core - so, if you have tools to target Cortex-M4, you can use them.

The Nordic BLE protocol stack - the "SoftDevice" - is supplied as a binary; so you would have to ensure that your tools supported a suitable interface.

The SoftDevice also requires a specific memory layout - so you would have to ensure that your tools can cope with that.

It seems it can be done, but is not a thing that Nordic support:
