    [Question] Need AVS & AVS app test guide

    soohwan_2562956

      Hi,

      I'm testing avs application with BCM43907 evb + SDK 5.1 but I can not find any application test guide for "demo/avs" & "demo/avs_app".

      In "demo/avs" I can find "talk" command but not in "demo/avs_app" and also I can find "connect" command in "demo/avs_app"

      but not in the "demo/avs", can any one tell me what's the difference between "avs_app" and "avs"?

      what's the test procedure for sending a voice command and get response from the server?

       

      As I guess, I should connect to the Amazone server first and then send a voice command like "joke.wave" in the SDK right and then

      get a response from server right?

      If so, why "connect" command and "talk" command is in different application seperately?

       

      If there is any breif test guide about AVS please let me know.

       

      Besides test procedure I get an error while connecting avs server like the following log.

          The demo.avs application demonstrates how to interface with Amazon's AVS using standard WICED components.I am trying to provide a general outline to implement the avs provided in WICED.

          1. Before compiling and running the application for the first time, users will have to modify the AVS_REFRESH_TOKEN, AVS_CLIENT_ID, and AVS_CLIENT_SECRET defines in avs_app_dct.h. The value of these parameters can be generated by running snip.avs_authorization application.
          2. Edit the wifi_config_dct.h to set the AP settings before compiling the avs_app.
          3. Boot the board and wait until 'Connection to AVS established' message is displayed.
          4. Type 'talk' and press enter in the console window. AVS should respond with a joke that is played on the speakers.
          5. Similarly, by using the play/pause command, you can use simple voice commands like tell me a joke and AVS should respond back.

          The avs app demonstrates that the voice commands are processed and the appropriate response is played on the speaker.

           

          The demo.avs_app application demonstrates how to interface with Amazon's AVS using the WICED avs_client service library. I am trying to list out the procedures first for this application.

          1. Before compiling and running the application for the first time, users will have to modify the AVS_APP_DEFAULT_REFRESH_TOKEN, AVS_APP_DEFAULT_CLIENT_ID, and AVS_APP_DEFAULT_CLIENT_SECRET defines in avs_app_dct.h
          2. Edit the wifi_config_dct.h before compiling the avs_application.
          3. Once the network has been correctly configured, boot the application and wait until the message "Begin app mainloop" is displayed on the console. Note that SNTP is initialized during application startup and the SNTP has an initial delay of between 300 milliseconds and 77 seconds as per RFC guidelines.
          4. Boot the board and wait until 'Begin app mainloop' is displayed
          5. Issue the 'connect' command to initialize the network connection to AVS.
          6. Press the Play/Pause button and speak a simple voice command such as tell me a joke

          The setting of timers and alarms is supported by avs_app which was not there in avs. Set an alarm for 11:00 should result in a statement like whether the alarm should be 11 in the morning or in the evening. The mic should then be triggered automatically for the user reply.  Playback may be initiated via voice "Play radio" or "Play music from TuneIn." AVS should respond asking what type of music you would like to hear. You should also be able to stop music playback from the Alexa application as well as change the volume.

           

          I hope the difference between both of the applications is somewhat clear now. avs_app uses the client service library whereas avs does not. The error that you have reported mostly occurs due to incorrect refresh token. Please let me know if you are still facing the issue and for your information, from SDK 5.2, you can see only the avs_app listed in SDK.

            Hi Rroy,

             

            Thanks for the detail guide,

            The error I reported had been solved and as you said it was due to the incorrect refresh token.

             

            Now I've got correct response by running "talk" commnad in avs demo but about "capture" commnad it seems the application reset whenever I run capture command.

             

            I didn't aware that I should press "play/pause" button when I run "avs_app" before say anything to AVS server.

             

            I will try this.

             

            P.S

            Do you know what's the "capture" command in the application?

             

            Best regards

            Soohwan.

              Hi Rroy,

               

              According to your guidance I'm testing avs_app however I got disconnect from AVS wile getting voice data.

               

               

              the following is the log I've got.

              the log marked in red is sudden disconnection and I have no idea why disconnected while procesing voice data.

                Hello Soohwan,

                 

                I was not able to reproduce the error. It seems to be an issue with particular AP. Once the connection to the AVS is established, it should work as expected. To understand the capture command, you can take a look at the avs_app_console.c which should be able to help you.

                  Hi Rroy,

                   

                  Yes except for the audio capture procedure all other fucntion seems ok.

                   

                  I ran the follow procedure

                   

                  1.run AVS

                  2.connect AVS bia "avs" command.

                  3.press "play/pause" button or type "capture" (it seems same function)

                  4.say "tell me a joke"

                  5. got disconnect right away

                   

                  I check DAC is correctly working however I never been checked wheather the ADC is ok or not.

                  I'm using general pin Mic below.

                   

                   

                  and used "demo.avs-BCM943907WCD1 download run" for compile.

                   

                  Do you have any idea?

                   

                  Best regards

                  Soohwan

                    Why the demo/avs_app is removed by sdk-6.0?
