Random Internet packets don't get transmitted to RF by transmit-capable I-gates. There are very specific rules implemented by both APRS-IS backbone servers and I-gates to ensure the local RF channel isn't jammed by excessive IS->RF relaying, and only packets of interest to the local RF neighborhood are forwarded.
For an Internet packet to be transmitted to RF, it has to pass one of the following rules:
1. The packet must be an APRS text message addressed to an RF station whose own packets were forwarded to the Internet by the specific I-gate.
2. The packet is a position report packet of an Internet-relayed station that has just sent a rule#1 text message.
3. Any other packets that the I-gate is specifically (and not defaultly) configured to relay.
So, if your APRSdroid system isn't sending text messages addressed to RF stations local to your I-gate, nothing from it will be transmitted by the I-gate unless you set up filters to cause the backbone server to send those packets to the I-gate, and more supplemental filters to force the I-gate to transmit those packets that don't meet rule#1 or rule#2.
Better off attaching an HT to your Android phone so you can send RF packets directly from the location where your phone is at. :-) Forcing packets just from the phone's callsign is inappropriate. What if the phone is nowhere near the I-gate? Sending non-local packets to the local RF network just clutters the limited-bandwidth RF channel.
Hope this helps explain how I-gates are supposed to work.

I have YAAC configured as a two way iGate. I'd like the packets I send from my phone using APRSDroid to be transmitted locally by my iGate. The phone packets are reaching APRS-IS as I seem them on aprs.fi. But they do not transmit from the IGate. I must be missing something. Thanks
