示例2: readTxPowerLevel

void readTxPowerLevel()

    DataContainer* dc = DataContainer::getInstance();
    uint8_t *tx_power_level;
    tx_power_level = (uint8_t*) malloc(sizeof(uint8_t));

    // resolution of 1 dBm.
    //
    // Units of dBm are decibels relative to 1 mW of power, hence, 0 dBm 1 mW.
    // 1/100 mW is -20 dBm and 100 mW is +20 dBm. Powers less than 1 mW are always negative dBm values, and powers greater than
    // 1 mW are always positive.

    errno= 0;
    int result = bt_gatt_read_value(dc->getTxPowerServiceInstance(), dc->getTxPowerLevelValueHandle(), 0, tx_power_level, sizeof(uint8_t), 0);
    if (result < 0) {
        qDebug() << "XXXX bt_gatt_read_value - errno=(" << errno<< ") :" << strerror(errno);
