Hi

Hi,

i got the same delay on Characteristic Write in all my Android devices with BluetoothLE.

I would have liked to overwrite the "DoWriteCharacteristic" method, but unfortunately the "TAndroidBluetoothLEManager" class is defined in the "implementation" of the "System.Android.Bluetooth" unit and I can not inherit it and overwrite the method.

I only need to try to set the callback timeout with a lower value then 5000ms!!

I tried btle on macosx, ios and android and i have no problems but in Android, i'm using 10.2.3 but i have this problem from XE10

tnkx

Ivan

    I haven't installed Delphi for Android, but...
    1. Try to copy .PAS with TAndroidBluetoothLEManager to the project's folder. Modify as needed. Rebuild the project.
    2. Create a RSP with request to add the ability to change the timeout.

    Not much choice but to either patch the unit, or to write Bluetooth support yourself (or perhaps request an enhancement)

    David Nottage I suggested it 2 days ago, but my message is still not shown in the thread. I hope the topic starter saw it.

    Ivan Revelli I believe that anti-spam protection has worked, because there is a link in the message. As a topic starter you can mark it as not a spam.
