Windows: writeValue with large data not working

[ohdonpiano]

Hi,

what is the maximum size for the Uint8List value for the writeValue method?

I've a laptop with BLE 5.2 and windows 11.

I'm trying to change a characteristic of a custom pcb, that uses a nordic micro with BLE 5.2

writeValue is working with a packet of 16 bytes

is not working with a packet of 230 bytes, which is supposed to work with BLE 5.2.

Indeed there is no issue at all using Mac, iOS or Android with the same packet of data.

The effect on the windows build is that client side, writeValue is executed but there is no effect, PCB side the change of characteristic is not received at all.

Is there some trick I'm missing?
