Description
When app is operating as server to advertise services the central can connect and read values from the qt advertised service. When attempting to write values back to the service from the central, qt service returns an invalid offset.
QT Source
osxbtperipheralmanager.mm
if (request.offset > data.length || request.value.length > data.length - request.offset) return CBATTErrorInvalidOffset;
The offset is zero, so if the new value request.value is longer than the current value data it throws an error setting the initial value to something longer. QT then erorrs saying:
