Possible to send/receive data mid-call using androids?

Postby Turbine » Wed Mar 24, 2010 6:54 pm

Alright this is my idea, but I need to know if I should pursue it or leave it alone.

I'm interested in developing some form of method in which data is transfered between two android devices once a call is established. I'm not sure if Android has functionality to read the sound data from a phone call, or if it would be possible to "monitor" for white space and inject sound that can be parsed by the other phone, creating some form of data transfer.

The main hook of this idea is to transfer data over the air, device-to-device, full duplex, and the phones process this data and do something with it. On call-start or call-end, it doesn't matter. Just trying to figure out if this is possible.

Peer to peer data sharing over the life of the phone-call. VERY small amounts of data. 1-500 bytes.

Any ideas? Is this possible, or is this asking too much?
