[SR3 52 FW V1.2] OPUS migrate and ANR

[Judge]

hi ,

1. How do I migrate the codec OPUS part of SR3 ? I want to use it for audio. But migration always fails. Any migration examples?

2.How effective is ANR work? Are there any quantitative parameters for the effect? What restrictions do I have on using it?

Hi, sorry, I don't understand what you want to migrate. Migrate OPUS to where? Any error messages during migration?

The SR3 only includes a demo version of ANR which adds a beep to the signal at regular intervals. If you want to get the full version contact vocal.com, maybe they have some numbers on the efficiency as well

hi Stian，

• For example, I want to transplant OPUS to this project:

nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_uart

I collect the audio data and send it to my phone through OPUS encoding.

Unable to resolve this error, .h file has been included.

hi Stian，

Will there be a 52840 version of SR3 in the future ? Because I found my 52832 RAM was not enough ! 

I use OPUS codec  which consumes a lot of RAM.

You can use the opus library on nRF52840 as well. Just start a project for the nRF52840 and include the opus codec.

hi Stian，

Can you provide a simple demo that has already migrated the OPUS codec?

Compilation has a lot of errors, and I can't fix them.
