Hi team,

Further Queries wrt above case.

1. can we detect microphone  with the help of NUS with windows OS? can we set up a NUS profile and integrate to detect microphone via BLE? 

2. If yes, let me know few initial steps to start with this process.

Thank you

Hi,

By NUS, do you mean the Nordic UART Service? There is no native support for NUS in Windows. If you intend to communicate over NUS/BLE with a Windows PC, you need to write your own application to handle the Nordic UART Service and interface towards the Windows OS. 

The usage of NUS in the Smart Remote 3 firmware is not related to the audio/microphone usage, only for a CLI over BLE, so you would have to modify the firmware to report anything regarding the microphone.

Best regards,
Jørgen

ok ..Thank you Jorgen

'modify firmware' related query ...

1. Can we add BLE audio profile  in the "nRFready Smart Remote 3 nRF52 v1.2.1alpha" firmware for  windows ?

2. If yes what are the files need to be modify to detect PDM mic in windows?

Bluetooth LE Audio relies on core features from Bluetooth 5.2 specifications, see LE Audio FAQs. The "nRFready Smart Remote 3 nRF52 v1.2.1alpha" firmware is based on nRF5 SDK v14.2.0, which included support for SoftDevice s132 v5.0.0. This SoftDevice version was released in 2017, and qualified according to Bluetooth v5.0 specifications, long before Bluetooth LE Audio specifications were available. Due to this, it would be very hard to add any support for LE Audio in this firmware.

LE Audio is also not supported in Windows, as far as I know.

selected and purchased  Nordic  remote as it has builtin microphone with other remote features. while purchasing

we didnt know about audio support only with ubantu.  But our requirement is microphone based remote only.

how to resolve this now.

It is not impossible to create an application/driver to use the audio part of the Smart Remote 3 product with a Windows OS, but we do not provide any examples/implementation on this platform. You will have to research and implement this support yourself if you want to use the device with Windows. The Smart Remote 3 product page specifies "Host-side software suite for Linux" under the highlights.
