connects to your Bluetooth speaker and uses your phone as a microphone

[Robert Jimenez]

Hi everyone!

I am new to App Inventor 2, but have been playing around with it and absolutely love it! It is fun :)

I wanted to begin working on a project that I have had in my head but not sure if App Inventor 2 can help me complete it.

I am looking to create an app similar to this one https://play.google.com/store/apps/details?id=com.xpressdigi.voiceplus

So I can connect the app to a bluetooth speaker and use my smartphones microphone to transmit my voice to the bluetooth speaker. Almost like using the phone as a microphone at a party and the bluetooth speaker is connected directly to the phone.

Can I do something like this with App Inventor? If so, any suggestions on how to get started?

Thank you for your help :)

Hi Robert,

I'm not 100% sure this is possible with base App Inventor, but there may be extensions that can help you out. For example, we provide a Bluetooth low energy extension that you could use to send the content to the speakers using the Bluetooth audio profile. Right now, my guess is that you could use the sound recorder component to record the audio, and once it is done recording send the audio to the speaker. However, events in App Inventor tend to not be stream based, so capturing continuous audio and sending it in real time to the speaker would require building an extension that can handle the audio stream from the microphone specially and segment the audio appropriately into data packets to be sent to the speaker. Alternatively, if you've paired your device with the speaker, simply playing back the audio might be sufficient if it is redirected over Bluetooth to the speaker by the operating system.
