how do we get to know Users Android device MTU size ?

Question

We have our application in Xamarin forms for android devices how do we get to know the MTU size of the android device which user is using ?

I should be notify user if users device MTU size is not supported to use our application must check the MTU size of user device first.
Also is there a way to notify user before installing application from playstore? or before showing launch screen in the application.

Hello,

If you mean the MTU size of android device. For Android phones, MTU size is default (23 bytes) and couldn't be changed.

If you mean the Bluetooth MTU size in Android, you can refer to requestMtu to get more details.

The following simple code shows how to use it in Xamarin:

   public void setMTU(BluetoothGatt gatt, GattStatus status)  
   {  
   	if (status == Android.Bluetooth.GattStatus.Success)  
   	{  
   		//requestPriorityHigh();  
     
   		gatt.RequestMtu(182);  
                   // etc.  
   	}  
   }  

Best Regards,

Alec Liu.
