Summary
The project generates multiple Nugets called 'Laerdal.McuMgr' & 'Laerdal.McuMgr.Bindings.iOS|Android|NetStandard' (note: NetStandard is still WIP). The goal is to have 'Laerdal.McuMgr' provide an elegant high-level C# abstraction for the native device-managers that Nordic provides us with for iOS and Android respectively to interact with nRF5x series of BLE chips:
From the respective 'Readme' files of these projects:
<< nRF Connect Device Manager library is compatible with McuManager (McuMgr, for short), a management subsystem supported by nRF Connect SDK, Zephyr and Apache Mynewt.
It is the recommended protocol for Device Firmware Update(s) on new Nordic-powered devices going forward and should not be confused with the previous protocol, NordicDFU, serviced by the Old DFU Library.
McuManager uses the Simple Management Protocol, or SMP, to send and receive message requests from compatible devices. The SMP Transport definition for Bluetooth Low Energy, which this library implements, can be found here.
The library provides a transport agnostic implementation of the McuManager protocol. It contains a default implementation for BLE transport. >>
The following types of operations are supported on devices running on Nordic's nRF5x series of BLE chips:
Upgrading the firmware
Erasing one of the firmware images stored in the device
Rebooting ('Resetting') the device
Downloading one or more files from the device
Uploading one or more files over to the device
Note: The library doesn't support "Windows Desktop" applications (Windows/UWP) just yet (WIP).
✅ Nuget Platform-Support Matrix
Stack | Android | iOS | MacCatalyst (MacOS / iPad / iOS) | Windows / UWP (NetStandard2.0) |
---|---|---|---|---|
DotNet 8+ | ✅ Min 5.0 / Recommended 11.0+ / Max 14.0 <br/> (api-levels: 20 / 30 / 34) | ✅ 17.0+ ( requires iPhoneXR or better ) <br/> ( sdk: iphoneos-sdk 17.5 ) | ✅ 13.1+ <br/> ( MacOS: 10.15+, iOS/iPadOS: 13+ ) | 🚧 (Much much later ...) |
❗️ Salient Points
For the firmware-upgrade to actually persist through the rebooting of the device it's absolutely vital to set the upgrade mode to 'Test & Confirm'. If you set it to just 'Test' then the effects of the firmware-upgrade will only last up to the next reboot and the the device will revert back to its previous firmware image.
Make sure to explicitly un-bond any app (including the NRF apps!) from the devices you are trying to upgrade. Any device in the vicinity that's still bonded will cause problems in case you try to perform a firmware-upgrade on the desired device.
Make sure to clean up after your apps when using the firmware-upgrader, device-resetter or firmware-eraser. Calling .Disconnect() is vital to avoid leaving behind latent connections to the device.
At the time of this writing the generated ios-nugets are built based on the iphoneos16.2 sdk
For the time being Nordics' Android/Java libs are compiled in a way that emits Java1.8 bytecode so as to keep the libraries backwards compatible with versions of Android all the way back to 7. Our Java "glue-code" under 'Laerdal.McuMgr.Bindings.Android.Native' is compiled in the same fashion.
To compile the iOS/MacCatalyst libs on localdev with their default settings you will need MacOS with XCode version 15.4 and iPhoneOS SDK 17.5. The reason McuMgr libs only support iPhones that can run iOS17 or better is simply because as of April 2024 all iOS and iPadOS apps submitted to the App Store must be built with a minimum of Xcode 15.x and the iOS 17.x SDK! The iOS 17.x SDK only supports iPhones/iPads that can run version 17.x of their respective OSes or better.
🚀 Using the Nugets in your Projects
Add the following Nuget packages.
Laerdal.McuMgr
Laerdal.McuMgr.Bindings.iOS (only add this to those projects of yours that target iOS)
Laerdal.McuMgr.Bindings.Android (only add this to those projects of yours that target Android)
Laerdal.McuMgr.Bindings.MacCatalyst (only add this to those projects of yours that target MacCatalyst aka MacDesktop+iPad)
Laerdal.McuMgr.Bindings.NetStandard (WIP!) (only add this to those projects of yours that target Windows/UWP)
Make sure to always get the latest versions of the above packages.

🏗 IDE Setup / Generating Builds on Local-dev
Note#1 There's an github-actions.yml file which you can use as a template to integrate the build in your github workflows. With said .yml the generated nugets will work on both Android and iOS.
_
Note#2 To build full-blown nugets that work both on iOS and Android you must use MacOS as your build-machine with XCode 14.3+ and JDK17 installed - have a look at the .yml file to see how you
can install java easily using 'brew'.
_
Note#3 If you build on Windows the build system will work but the generated nugets *will only work on Android with MAUI apps* but they will error out on iOS considering that the 'iOS part'
of the build gets **skipped** in Windows quite simply because in Windows we cannot use tools like 'sharpie' and the 'iPhoneOS' SDK that comes with XCode.
To build the nugets from source follow these instructions:
1) Checkout
git clone git@github.com:Laerdal-Medical/Laerdal.McuMgr.git mcumgr.mst
# or for develop
git clone git@github.com:Laerdal-Medical/Laerdal.McuMgr.git --branch develop mcumgr.dev
2) Make sure you have .Net7 and .Net-Framework 4.8+ installed on your machine along with the workloads for maui, android and ios
# cd into the root folder of the repo
sudo dotnet \
workload \
install \
ios \
android \
maccatalyst \
maui \
maui-ios \
maui-tizen \
maui-android \
maui-maccatalyst \
&& \
cd "Laerdal.McuMgr.Bindings.iOS" \
&& \
sudo dotnet \
workload \
restore \
&& \
cd - \
&& \
cd "Laerdal.McuMgr.Bindings.MacCatalyst" \
&& \
sudo dotnet \
workload \
restore \
&& \
cd - \
&& \
cd "Laerdal.McuMgr.Bindings.Android" \
&& \
sudo dotnet \
workload \
restore \
&& \
cd -
# note theoretically 'dotnet workload restore' on the root level should also do the trick but in practice it sometimes runs into problems
After running the above command running 'dotnet workload list' should print out something like this on Windows:
> dotnet workload list

3) Make sure that Java17 is installed on your machine along with Gradle 7.6 (Gradle 8.x or above will NOT work!)
4) Make sure you have installed Android SDKs starting from 31 up. You will need to install them using the Visual Studio installer. If you use Rider you will need to install them a second time using the Rider Android SDK manager too!
5) Set MSBuild version to ver.17
6) On Mac make sure to install XCode 14.3+ (if you have multiple XCodes installed then make SDK 14.3+ the default by running 'sudo xcode-select --switch /Applications/Xcode_XYZ.app/Contents/Developer').
7) On Windows you will probably have to also enable in the OS (registry) 'Long Path Support' otherwise the build will most probably fail due to extremely long paths being involved during the build process.
8) Open 'Laerdal.McuMgr.sln' and build it.
You'll find the resulting nugets in the folder Artifacts/
.
Note: For software development you might want to consider bumping the version of Laerdal.McuMgr.Bindings.* first and building just that project
and then bumping the package version of the package reference towards Laerdal.McuMgr.Bindings inside Laerdal.McuMgr.csproj and then building said project.
If you don't follow these steps then any changes you make in Laerdal.McuMgr.Bindings.* won't be picked up by Laerdal.McuMgr because it will still
use the cached nuget package of Laerdal.McuMgr.Bindings based on its current version.
To make this process a bit easier you can use the following script at the top level directory (on branches other than 'main' or 'develop' to keep yourself on the safe side):
# on macos *sh
dotnet \
msbuild \
Laerdal.Builder.targets \
'"/m:1"' \
'"/p:Laerdal_Version_Full=1.0.x.0"'
# on windows powershell
& dotnet ^
msbuild ^
Laerdal.Builder.targets ^
'"/m:1"' ^
'"/p:Laerdal_Version_Full=1.0.x.0"'
# Note: Make sure to +1 the 'x' number each time in the aforementioned scripts before running them.
Known issues
- Intercepting logs emitted by the underlying McuMgr libs is supported in iOS through the 'LogEmitted' family of events. But the same family of events in Android is never triggered from the underlying McuMgr libs of Nordic (it's only triggered when we want to emit certain warnings ourselves) so logging in Android is very limited.
