trying PB_SAMPLES gives the same result. Trying PCM or I2S gives the same result, but different interface number. With older fimware (R9.1, Legato 18.06) the result was also the same. Could anyone help with this issue?

Best regards, Frans.

I just tried the this on the mangOH yellow and got the same error.

WP77xx series don’t support audio.
If you need PCM/I2S audio then use WP76xx series instead.

Hi Jay,

According to the AirPrime WP77XX Product Specification r2 on page 68 audio should be there:

“4.16 Digital Audio
The AirPrime WP77XX provides a 4-wire digital audio interface that can be configured
as either PCM (Pulse Code Modulation) or I 2 S (Inter-IC Sound).”

However, there is a note that audio availability is firmware-dependent. Is there anybody from Sierra Wireless than can confirm if current firmware supports audio?

Best regards,
Frans.

@FransKanters,

So the WP77 builds are specifically data only builds from a Qualcomm perspective. I do not know explicitly if it affects the non voice call related functions of the device but I expect it would do hence the failure of the API calls.

Dear Matt,

Thank you for your response! I was afraid of that answer…:wink:

Best regards,
Frans.

Has this been confirmed? We are trying to simply record audio from the on board digital mic into a file on the MangOH Yellow (WP7702). We don’t want voice calling, just audio recording. If this is disabled in the firmware, how can we use the on board peripherals?

8

I think this is Qualcomm chipset limitation that there is no audio on mdm9x06.

@zirunhong, @jyijyi

As far as the feedback and understanding I have is concerned the silicon might be capable but the builds that come out of QC are only data enabled, hence the limitation. If you want a hard answer which the development team check you will need to raise a ticket through your commercial channel (difficult I know if you have bought a mangoh from Digikey) but that’s the best answer we can give on the forum.

Regards

Matt

Hi Matt,

Thanks for your reply!

11

Can you please confirm if the audio API’s can be used without the active voice call to read and write PCM samples. The application does not make use of VoLTE and there is no voice call. The application itself runs VoIP and need to get the PCM samples from/to mic/speaker for processing.

12

Audio API cannot be used in wp77 module

13

Yes I understand, I will use WP76xx + MangoOH Green. In this configuration, Can the application running on the application processor access the raw PCM samples directly from/to mic/speaker via audio codec. We will not use voice call feature. The VoIP application itself runs on the application processor and it needs PCM samples for processing.

14

You can check if these files are raw data.
I remember .wav file can be played in mangoh board
