Android-nRF-Toolbox VS kable

You can use this library. Here is an example app that uses it (the actual code is in the profile_... directories). If you don't use a library you will end up with code like this.

https://github.com/JuulLabs/kable this repo has been active but is notably pre 1.0

if you are using BLE & kotlin, I enjoyed using https://github.com/JuulLabs/kable

The BLE is trash on Android. Try using this for both android and iOS: https://github.com/JuulLabs/kable

https://github.com/JuulLabs/kable I have never used this but the readme has a nice overview of the primary areas of how a client interacts with a bluetooth device

unrelated but if you are familiar with coroutines / flow this library is loads better than the archaic android ble sdk https://github.com/JuulLabs/kable

As a beginner Android developer trying to develop a BLE app, I found the existing resources out there mostly unhelpful. With this repo I am hoping to build an app that will be helpful for others. I'm using Kable. There are some issues with this app so I'd appreciate feedback and review, even if it is just about the general structure.

To write the Android app to do all the BLE stuff, suggest using a third-party library that hides a lot of the gory details. If doing Kotlin, something like https://github.com/JuulLabs/kable or in Java https://github.com/weliem/blessed-android.

If you are on Kotlin and are proficient on coroutines you can try Kable: https://github.com/JuulLabs/kable wich is very cool to use as long as you have some experience with coroutine jobs and scopes. I think it haves potential to be the best Android BLE library but still is in Beta and there are some weird things still happening (like missing packets when you subscribe on notify) but haves a lot of potential.
