How to receive voice data from Nordic 52832 remote control in embeded linux?

[Ralph]

Hi,

Does anyone know how to receive voice data from Nordic 52832 remote control in embeded linux ?
Does Nordic provide any package for this purpose ?

Thanks

The whole point of Bluetooth and GATT is that it is hardware agnostic - so the fact that it's a Nordic chip is irrelevant to Linux.

So the thing to search for is "Linux GATT"

What "remote control" are you using? Is it a Nordic SDK example?

There are Linux versions of nRF-Connect and nRF5-BLE-driver:

Hi Ralph,

Are you referring to the Nordic Smart Remote 3? It should be possible to download the FW for the SR3. Otherwise, the Nordic Thingy:52 is also able to stream voice from the Thingy to a smartphone or vice versa. The Thingy SDK is also available for download here. This Github documentation could also be useful. In addition, the Thingy smartphone apps are also available to download (for iOS & Android).

Kind Regards,

Bjørn

Hi,

We could receive remote's key with HID (HID over GATT) ,but can't receive voice data.

The remote control we use is nRF6939.

We have tried this pdf. (http://infocenter.nordicsemi.com/pdf/Voice_input_module_UG_v1.1.pdf ). But this not work on embedded linux.

So we want to know how to receive voice data with HID in embedded linux?

Does Nordic provide any package for this purpose ?

Thanks.

Yes the nRF6939 is the Smart Remote 3. Have you taken a look at the SR3 Software? The SW should have voice input support & audio compression using OPUS, BroadVoice & ADPCM. May I ask why you want to use embedded linux instead of just C?
