Re: [android-developers] Send dtmf tone on uplink

I'd like to add my voice to this topic also, as I have several devices
which are DTMF enables (relays) and being able to use an app to send
the tones would be extremely helpful, having to drive 25 miles to open
and close greenhouse windows is a major chore and while I have the
temp and humidity uploaded nicely, its hard to write an app that can
tell if plants are starting to droop with heat that makes DTMF enabled
relay so useful.
