not a support questionHi, I don't know if I am hitting a bug, or a feature that does not make sense to me. I wired up a couple of RFM12 (not B) modules (just the modules I bought) to a couple of Arduinos. I downloaded the latest RF12 Arduino lib from the google code page, installed, and ran the demo program. Everything is working like magic! Thanks for this very fine project to have created!
There is only one thing that I do not understand. I set up the 2 nodes as numbers 1 and 2, and verified that the settings took. When I send data through the serial console of node 1, like this "5,0a", which I believe means send the number "5" to all nodes on the 212 group, I receive the data on the other node (#2), and it sends an ack back to #1, which displays "-> 1 b", and "OK 193". This is what I expect.
But when I do the same with the node ID of the other node like this: "5,2a" The data does show up on the other node (#2), I see the 5 show up just as before, but node #2 does not send an ack back this time. On the sender (#1) all I see on the console is "-> 1 b". There is no "OK". It is as though I sent "5,2s", for no ack.
In short, the software is only sending acks when data is sent to node 0 (everyone), but not sending an ack when data is sent to a specific node.
