Ну так там переполнение буфера, скажи спасибо, что тебе не дают это собрать.
void QLowEnergyControllerPrivate::readServiceValuesByOffset(
uint handleData, quint16 offset, bool isLastValue)
...
quint8 packet[3];
...
putBtData(offset, &packet[3]);
т.е. ты пишешь quint16 по адресу последнего элемента массива quint8.
Спасибо! Теперь понятно. |
