Scanning BLE beacons

sierdzio

This function was introduced in Qt 5.12.

Maybe you are using older Qt version?

@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.

~~no, it does not, and here you come in and either~~
~~- expand DeviceInfo class that comes with the BTLE example and you're using~~

or
~~- create your own interface class that wraps around QBlueToothDeviceInfo~~

written 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

jsulm

@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.

You can install newer versions using Qt Online Installer...

I see no options for Linux there.

I tried also Properties-> Execute : Anyone
Then Double click -> Execute in terminal

It's linux-x64. I'm not sure Raspbian is 64 it's 32 as far as I know.

sierdzio

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

jsulm

@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.

@jenya7 said in Scanning BLE beacons:

No it will not. RaspberryPi is ARM, not x86...

I see. Any forecast when a newer version will be available for RaspberryPi ?

jsulm

@jenya7 This is something you have to ask Debian.

Thank you guys.
