Or you want to read the data that the device is sending? To do that, you need to connect to it first. https://doc.qt.io/qt-5/qtbluetooth-lowenergyscanner-example.html#connecting-to-services
not with beacon, beacons are not connectable. And the Qt Api gives no way to identify that.
what the op is looking for should be in
https://doc.qt.io/qt-5/qbluetoothdeviceinfo.html#manufacturerData-1No. It has to get a payload. Every beacon has a payload (20 bytes) of my own data. App. I wrote on my phone (Android) gets all beacons and I see my payload too.
Wat's the point to get a beacon? To see it's name, rssi, and other fields ? I need the data it sends.@jenya7 I'm not sure to what you're replying ?
I said, your payload can be accessed via https://doc.qt.io/qt-5/qbluetoothdeviceinfo.html#manufacturerData-1
I do it too.

I see. But info has no such field.
void BT_DEVICE::AddDevice(const QBluetoothDeviceInfo &info) { info. //no manufacturerData } -
This function was introduced in Qt 5.12.
Maybe you are using older Qt version?

no, it does not, and here you come in and either
- expand DeviceInfo class that comes with the BTLE example and you're usingor
- create your own interface class that wraps around QBlueToothDeviceInfowritten before the edit of
void BT_DEVICE::AddDevice(const QBluetoothDeviceInfo &info)
{
info. //no manufacturerData
}@sierdzio is probably right, what version are you using?

It is 5.11.3
-
@jenya7 If you follow the link from @J-Hilk you will see that you need Qt >= 5.12 for that method.

Wow. On Linux the latest available from repository is 5.11.3.

Raspbian is ARM, so it won't work anyway.

@jsulm said in Scanning BLE beacons:
@jenya7 @sierdzio Ah, it's on ARM. In this case you will need to build Qt by yourself if you require a newer version.
Actually it's Debian fitted for Raspberry. I think 32-bit version will run but I see only 64-bit version available.
