      One workaround might be for the application to remember the previous input and then select it x seconds after issuing the command to 'power on'. I'm guessing the soundbar won't tell you the current input when it is in standby mode, but if it does you could query the current input before powering on instead of storing the last used input.

      @david Thanks for your great effort regarding this issue. I'll be trying out this new letter in the app store to check if it passes the barrier.

      Hi @Jodie_space!

      Unfortunately there is no built in support for recording to a video file on the SD card. There are two camera data streams available: one for taking still pictures and one for showing a preview video like you have in a "regular" digital camera. No support for actual video recording.

      Now, it doesn't say exactly what your project is supposed to do or what you want to use the video for, but perhaps it would be possible to generate the actual video file as a post processing step? This might work If you don't intend to use the actual video file on the Spresense board itself after recording. In that case you could save the frames from the preview video as separate image files on the SD card instead of displaying them on a display etc. Then, when the recording is finished, plug the SD card into your PC instead and combine them into a video file using an external tool such as ffmpeg.

      This workaround might not work for you - it depends on what you want to accomplish - but it is the simplest solution I can come up with.

      I found this similar thread that might be interesting to you:

      Hi @monotaskr,

      Nice to hear about your ideas! Unfortunately I am not able to help out with the actual project design so I will just give some generic recommendations to help you get started

      As a first step I'd suggest you have a look at the sample applications available in the Spresense SDK and/or Arduino library if you haven't already. Getting an idea of how audio works in Spresense and what it can do might help you decide the scope and direction of your project. The audio system might seem a bit complicated at first, but start playing around a bit with the samples to get a feel for it. There are several audio related apps in both the Arduino and SDK development environments, but remember that they are just examples. Don't let their scope limit you!

      Then you can start to think about what sampling devices you think are suitable for your project and figure out what adaptations might be needed to connect them to the Spresense mic inputs.

      Here are some general pointers to interesting audio related sections in the documentation:
      https://developer.sony.com/develop/spresense/docs/sdk_developer_guide_en.html#_audio_subsystem
      https://developer.sony.com/develop/spresense/docs/arduino_developer_guide_en.html#_audio_library
      https://developer.sony.com/develop/spresense/docs/hw_docs_en.html#_how_to_use_microphones

      You might also find this forum thread interesting if you haven't seen it already:
      https://forum.developer.sony.com/topic/172/microphone-array-suitability/2

      I hope it helps!

      Hello Neo,

      Those files were released as a best effort for community but Android 10 is not officially supported for Xperia X
      If you want to give it a try you can check the bug tracker for the known bugs and progress

      Please post future questions on the bug tracker
      https://github.com/sonyxperiadev/bug_tracker/issues

      Hi @david

      Thank you for that. That indeed makes sense. The easy solution for me then is to only query the active input when the AVR is powered up.

      Hello,
      so finely I was successful. After I recompiled everything again I found, that phone H4113 XA2 is codenamed "Pioneer" and not "Kirin". I did wrong setup of the first compilation. Now the AOSP 11 is up and running.
      Thanks for support!
      Best Regards

      @tornedoar said in main board Digital I/O:

      @TE-KarlKomierowski yes you are totally right, it would be a lot easier, but the company I work in, want everything in the cheapest way !!!!

      Ok, I understand.
      I don't know if it is of any help but the schematics for the extension board is open and free to download. So if you prototype with the extension board you should be able to copy the parts of the design that suits your needs. It could save time doing so (and money) for your company.

      Just a comment, you can ignore this if it is not feasible for you.

      Here is a link to the schematics: spresense-hw-design-files

      Hi @Kaawin,
      Using the setPlayContent to play DLNA content is not recommended I have had mixed results with it and lot of frustration...

      It is not your media server that needs to have the AVTransportservice that is for the sony receiver or speaker you want to play the music on.
      To make it easier for you to get the correct information your media server should hopefully support the service ContentDirectory. Otherwise you have to fill in the info using the provided examples, it is easy to get them wrong and the error messages you get (if you get any) is not that helpful.

      Unfortunately the code examples on developer world have some issues, so it is better to look here https://github.com/sonydevworld/audio_control_api_examples/tree/master/DLNA for examples.

      Hope this helped, and good luck!!!

      Arrgghh!!! The latest firmware update for the STR-DN1080 has removed the DIAL function from the receiver so my detection routine no longer works! The firmware updates the built-in Chromecast Audio device. Doing some UPnP searches, no DIAL device is detected. And the following file is no longer served by the receiver:

      Hi @tornedoar

      Unfortunately, Spresense is not supported in Matlab. If you want to use Arduino on Spresense then use Arduino IDE. Here is a link on how to get started: https://developer.sony.com/develop/spresense/docs/arduino_set_up_en.html

      You can use the same libraries and code as on Arduino. However, there are some differences: https://developer.sony.com/develop/spresense/docs/arduino_developer_guide_en.html#_functional_differences

      I hope this will help you.

      Best Regards,
      Kamil Tomaszewski

      P

      Sorry, has taken me time to get back to this problem, once I make the suggested change the error I got previously no longer appears when I compile the code. I now get other issues but that appears to be due to board differences.

      Thank you
