Amazon Dash Button's Wireless Audio Configuration

It doesn't work with android because of the wide variety of speakers and microphones on android vs the very few for ios. Many android phones can't even emit or record ultrasound.

If anyone wants to play with an audio modem which can run ASK (PSK and QAM too!) then try <a href="https:&#x2F;&#x2F;github.com&#x2F;quiet" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;quiet</a> which has Android and JS bindings<p>End shameless plug :)

I&#x27;d be interested to know how much potential advertising data is collected via these microphones.<p>Previous discussion: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10562207" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10562207</a>

Should Amazon have encrypted this transmission in some way or is the volume low enough that a plain text transmission of the wifi password not pose a threat?

Now the question is if there is a exploit in the rom and by crafting your own audio you can make the device much more interesting.

I thought this was really cool, and you don&#x27;t even need a Dash button to repeat it (just the app). I threw a mic on my desk and recorded the output real quick, and sure enough, it&#x27;s pretty easy to see the waveform. I was going to post the wav file, but without knowing a bit more about how the Dash links to my Amazon account, I&#x27;m a bit hesitant.<p>I&#x27;m going to have a run at reproducing this in Python. Should be fun!

incredible work, jay! I like how you described everything.<p>I think it&#x27;s going to be interesting when the Amazon dash buttons end up playing a role in next big DDOS...

I wonder how many tens of thousands of people have now unknowingly installed internet-connected microphones in their kitchens, garages, laundry rooms, and bathrooms.
