Finally we managed to integrate the GSM module on the FLOW with Android. Without the help from the Open Source community this would never be possible or would be possible after a LONG time :) At last FLOW can be used to send messages or just making calls. You can find out more information about this Open Source device as well as purchase one from our website at www.gizmoforyou.com Remember that this is all assembled and soldered by hand (as every Gizmo we make)
