[Interest] QT bluetooth module

[Shravan Singh]

Hello,

My name is Shravan Singh and I work for Blue Sparq company based in
Florida. We rely on QT a lot for creating applications that connect and
communicate with the embedded devices. We are currently working on a
project that uses EH-MC10 Bluetooth module and it communicates with the QT
app.

Since I am a beginner I wanted to understand how this communication works.
So I took bluetooth chat example to test it out.
Now the demo recognizes my device but it doesn't connects to it. I dont
know what is causing this problem.


I added this in the demo thinking that It would solve my problem but it
does not

Added this function in remoteselector.c


void RemoteSelector::startDiscovery()

{

    ui->status->setText(tr("Scanning..."));

    if (m_discoveryAgent->isActive())

        m_discoveryAgent->stop();


    ui->remoteDevices->clear();


    //m_discoveryAgent->setUuidFilter(uuid);

    m_discoveryAgent->start(QBluetoothServiceDiscoveryAgent::FullDiscovery);


}
Added this function in remoteselector.h
  void startDiscovery();


I have even changed the UUID to match my device UUID
static const QLatin1String serviceUuid(
"11223344-5566-7788-99aa-bbccddeeff00");

I see my device getting recognized

D/BluetoothLeScanner( 6935): onScanResult() -
ScanResult{mDevice=00:EA:18:00:A6:0C, mScanRecord=ScanRecord
[mAdvertiseFlags=6, mServiceUuids=[11223344-5566-7788-99aa-bbccddeeff00],
mManufacturerSpecificData={}, mServiceData={}, mTxPowerLevel=8,
mDeviceName=EH-MC10], mRssi=-55, mTimestampNanos=251762722824}

But nothing after that What can be the problem here

Thanks,
Shravan
