Bluetooth Framework / Re: Subscribe and event receiving data
« Last post by gn_torino on September 30, 2021, 07:24:36 PM »
OK, thanks a lot.
If I pair with my OS (Windows) it works.
To pairing it with the method , should I call RemotePairing before of after the connect Method ?

If I use both I receive a connected and disconnected event one just after the other and the device seems remaining disconnected.

Thanks
Best regards

Hello,

The error code 0x00051004 is WCL_E_BLUETOOTH_LE_INSUFFICIENT_AUTHENTICATION (Attribute server does not support the request received from the client.) https://www.btframework.com/errors.htm

It looks like your device requires authentication and may be pairing.

Bluetooth Framework / Subscribe and event receiving data
« Last post by gn_torino on September 30, 2021, 06:38:51 PM »
Hello,
thank for your support.
We are evaluating you library for BT LE commuication with a GATT communication with some characteristics.
We have been able to discover all services, characteristics and descriptors.
We have 4 characteristics :one Notifiable, one indicable, one write with no responde, one writable.

It has no security settings and it seems I have been able to subscribe to characteristics as I receive the result value equal to 0.
Anyway after that, the characteristic changed event is neves issued.

Following the online help I tried to call sequentially both methods
subscribe
writeClientConfiguration
but I receive an error on the writeClientConfiguration 0x51004

If I call just writeClientConfiguration i receive the error 0x51004.

The event handler is set before the BT connection. Is there any constrain on when setting the event handler?

Am I missing something in my settings ?
Thanks
Best regards
G.

Hello,

This error may indicate that the device sends invalid PDU or the device
requires authentication/encryption.

You an debug it only on device's side to see what device sends and receives.
Or with BLE sniffer.

Hi All!
In which cases "GATT protocol error" can occur?

It looks like Windows does not support LE audio at all.

Thanks for the help!
Which part does windows not support? The direct streaming of audio data to a single device? Or multiple?

Do you have a link to any references discussing this where I can read more? If it's something I can achieve via a linux server, etc, I will start looking into that as well.

Hello,

Bluetooth standard allows to do that however it does not look like Windows support this feature yet.

Bluetooth Framework / Multiple Bluetooth Audio Streams
« Last post by Lilee87 on August 17, 2021, 09:08:22 AM »
I am not very familiar yet with all the correct bluetooth terminology, so bear with me.  I have been able to successfully connect and subscribe to various services on BLE devices (like reading battery levels, and HR data).

I want to connect multiple audio devices, and individually stream audio to each of them.  I am not worried about syncing, or anything fancy like that. Just the ability to independently send audio stream data to multiple BLE speakers.

I can't find how to get started with this in the documentation. Any tips? Is there an example of doing audio (just a single stream) anywhere?

Hello,

It is hard to say what can be wrong. Can you describe what is your device and how do you connect to it with Bluetooth Framework and which oither tools do you use? Does it need pairing or something else?
