MotoMod :Having problem with Audio greybus protocol

lgamini

Hi Everyone,

 

I am using Moto Mod Audio greybus protocol [ I2S management protocol and Mods audio protocol ] to get I2S data from Moto Z phone audio player application. When i start playback from application, i am able to receive I2S data on Moto Mod I2S lines. But, if i stop playback from application, i am not receiving any message from greybus GB_I2S_MGMT_TYPE_STOP command. After that, playback also stopped. Hope someone can help me. Thanks in advance.

    Are you going through the Moto High Speed bridge, or using the PHY lines directly for i2s?

    Could you provide MuC logs?

    Thanks alot for your response.

    Right now, i am using I2S lines from phone Connector directly. [Made Dip Switch A2 as High on Mod]

    device_i2s_start_receiver_port function is called when i start playback from Moto Z phone. After that i am not receiving any command even if i stop player from application or changing volume keys of Moto Z.

    Here are the logs of MuC.

    Stupid question, are you registered for device_i2s_stop_receiver?

    Do you have logs of the stop, we're curious if the lower level greybus is being called but not making it to your handler somehow.  If that's actually the complete log including stop, this is very interesting...

    The problem is resolved.

    Actually i have already registered for device_i2s_stop_receiver call. But the problem is with device_i2s_start_receiver_port API.

    Due to a stupid bug, it was hung there. After fixing it, i am able to receive all next commands perfectly even stop also.

     

    Thanks very for much.
