[WIP] feature: 314 Linux BLE

[6d7a]

Description

Finally got around to do some work on #314
I created a bluetooth service that implements the functionality of the respective RPC protocol. I modeled the service after the Android example, let me know if I missed some feature.
As I mentioned in #314, I'm still uncertain about the when and where the channels between UI and BLE are set up. Could you give me a push in the right direction?

Thanks

Thanks a lot! It looks great!
I will have a further look and give more detailed feedback.
I will also answer your questions in #314

Thanks again for this helpful module!

The interconnection between libqaul's BLE connectivity-module and the Android BLE module is done in the branch ble-startup-fixing-rebased-06022023 and will be merged to main as soon as all remaining small problems are ironed out.

It is referenced to this PR #533

I rebased your branch on the ble-startup-fixing-rebased-06022023 branch and called it linux_ble pushed it to the qaul repo:
https://github.com/qaul/qaul.net/tree/linux_ble

And created the following PR from it: #539

---

I change the following things:

• Changed the BLE module to a library.
• The BLE module is running in an own thread within libqaul: https://github.com/qaul/qaul.net/blob/linux_ble/rust/ble_module/src/lib.rs
• The BLE module is directly called from libqaul here:

  qaul.net/rust/libqaul/src/rpc/sys.rs

  Line 74 in c523d15

  ble_module::rpc::send_to_ble_module(data);

TODO:

The BLE module should send it's messages to libqaul.

• I suggest a callback solution, as we did in Android, here:
  • https://github.com/qaul/qaul.net/blob/linux_ble/qaul_ui/android/blemodule/src/main/java/net/qaul/ble/callback/BleRequestCallback.kt

  • qaul.net/qaul_ui/android/blemodule/src/main/java/net/qaul/ble/core/BleWrapperClass.kt

    Line 154 in c523d15

    net.qaul.libqaul.syssend(bleRes.build().toByteArray())

Please don't hesitate to interact on it!
