nrfxlib-sys

This is a Rust wrapper for the Nordic nrfxlib set of libraries, primarily libmodem and liboberon for the nRF91* series chips (System-in-Packages). Supported chips are the following:

nRF9160
nRF9151
nRF9161

Any binary which uses this crate is going to need to provide a bunch of C library functions, because Nordic's library expects them. This includes, but is not limited to:

atoi
snprintf
strol
strchr

You can't just link newlib, because that defines memset which clashes with the compiler-builtin crate's definition of memset. Answers on a post-card please - for now I'm using tinyrlibc.

Using

NOTE: This crate does not follow semver. The version of this crate tracks the version of the underlying Nordic libraries.

In your own program or library, you can depend on this crate in the usual fashion:

[dependencies]
# A chip feature must be selected
nrfxlib-sys = { version = "=2.7.1", feature = ["nrf9160"] }

Because the modem library has its debug sections compressed and Rust's tooling doesn't have support for that by default, this crate either strips the debug sections or decompresses them.

By default the crate uses the llvm-tools that can be installed using rustup component add llvm-tools. In this case the debug sections get stripped.

If you'd rather have the debug sections decompressed, then disable the default features on this crate and enable the arm-none-eabi-objcopy feature. This will try to use the arm-none-eabi-objcopy binary that you can download from the ARM website. This one does have support for debug section compression.

This is a low level wrapper. You might prefer the blocking higher-level wrapper:

[dependencies]
nrfxlib = "*"

You might also prefer the async higher-level wrapper:

[dependencies]
nrf-modem = "*"
