Bluetooth BLE onMtuChanged

[Thap 0]

Hi,

 

for one of my Bluetooth BLE projects, the MTU has to be adjusted in the Bluetooth communication.

There is a "requestMTU" function in the Bluetooth framework for this, but how can I find out to which MTU the devices have agreed on?

 

When I call requestMTU(200) and look into the logcat profiler I see the following messages there:

BluetoothGatt: configureMTU() - device: <DEVICE> mtu: 200
BluetoothGatt: onConnectionUpdated() - Device=<DEVICE> interval=6 latency=0 timeout=500 status=0
BluetoothGatt: onConfigureMTU() - Device=<DEVICE> mtu=200 status=0

There is an "onMtuChanged" handler in "Android.JNI.Bluetooth.pas", but I don't know how to implement this or where.

 

I really just need a tip on how to include this event in a Bluetooth class from "System.Android.Bluetooth.pas".

I'm sure I'll be able to grind through the event myself through the remaining levels.

 

Does anyone have a hint or maybe an example code for me?
