requestMtu for large transmissions

[GaZaTu]

call https://developer.android.com/reference/android/bluetooth/BluetoothGatt#requestMtu(int) after the following:

tauri-plugin-blec/android/src/main/java/Peripheral.kt

Line 56 in ff0ccb8

this@Peripheral.gatt = gatt

or add a new rust/js api to do it manually please.

currently bt notifications on android are capped to 20 bytes of data because no MTU is being set.

Btleplug has an open PR to add mtu requests here

For now I added a request for a higher MTU on android, but there is no way to return the actual MTU because i use the btleplug structs internally. Usually it should be set to 517. This is the same that newer Android versions set automatically
Please try with the newest Version (0.5.3)

idk, i forgot that i'm using the rust side so this change doesn't even affect me xd.
but this isn't an issue for me anyway now since i managed to force a higher mtu on the server side.

This does affect the rust side.
It is implemented in the part calling the android plugin, which is used by the rust backend as well as the js commands.

So can I close this?
