In general the device search does add the found service UUIDs to the QBluetoothDeviceInfo. The relevant code section that extracts the service UUIDs can be found under:
http://code.qt.io/cgit/qt/qtconnectivity.git/tree/src/bluetooth/android/devicediscoverybroadcastreceiver.cpp?h=5.6.2#n469 Have you tried other Android devices? Maybe your device does not extract this type of information properly. At least on my test hardware the above lines produce the UUIDs. I suggest to debug around this area of code. -- Alex ________________________________________ From: Prashant Vaibhav <[email protected]> Sent: Wednesday, 12 October 2016 4:34:56 PM To: Alexander Blasche Cc: [email protected] Subject: Re: [Interest] QtBluetooth Low Energy: How to find my peripheral?

Hi all, I’m using QtBluetooth low energy API on Qt 5.7 / Android 5/6. Targeting API level 19 (android 4.4+). What are you using Qt 5.6 or 5.7? I’m using Qt 5.7.0. My problem is that I cannot find a way to decide which of the BLE devices returned during scan is mine: - The advertising data is inaccessible (no API). - The QBluetoothDeviceInfo.serviceUuids() function returns nothing (apparently it’s for classic bluetooth) - The QBluetoothDeviceInfo.name() function is null (empty string) So the only information I have is the rssi (QBluetoothDeviceInfo.rssi()), which is not enough to figure out the scanned device is ours. Furthermore, I cannot show a list to the user to pick the device manually, since all it will have is the signal level (and perhaps MAC address). I believe you may experience https://bugreports.qt.io/browse/QTBUG-54867. It was fixed in Qt 5.6.2 and 5.7.1. Alternatively you may cherry-pick the referenced patches into your Qt build. Thanks for the link, I checked and it doesn’t seem relevant to my issue. Our BLE device doesn’t have major/minor numbers in its advertising packet. It does have the primary service UUID (128 bit) which we are using to identify it on iOS (native code). Perhaps you meant https://bugreports.qt.io/browse/QTBUG-54867 ? -- Alex _______________________________________________ Interest mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/interest
