If the write operation is not successful, the \l error() signal is emitted using the \l CharacteristicWriteError flag. + Since this signal is an indication of a successful write operation \a newValue + generally matches the value that was passed to the associated + \l writeCharacteristic() call. However, it may happen that the two values differ + from each other. This can occur in cases when the written value is + used by the remote device to trigger an operation and it returns some other value via + the written and/or change notification. Such cases are very specific to the + target device. In any case, the reception of the written signal can still be considered + as a sign that the target device received the to-be-written value. + \note If \l writeCharacteristic() is called using the \l WriteWithoutResponse mode, this signal and the \l error() are never emitted. |
