RFM69Pi stops updating/freezes

Stitching together the ragged ends of the corresponding thread in the old forum.

I asked:

I gather that the serial comms path is two way - a command stream for changing various RF Module parameters (infrequent) and received packet chat (frequent) streaming back. A command gets a response, I can see that in the logs. My question was for the packet stream - does that get echoed back?

Reply from pb66:

The commands are echoed back from the RFM2Pi sketch as they are in the RF12 demo with a “>” prefix, emonhub then logs those as an “acknowledged command:”

Ok, got that direction thanks. How about a packet report travelling the other way?
i.e. does something such as a ? 10 147 0 0 0 0 0 120 95 245 7 (-68) get echoed back to the originator since the read is posted with echo enabled?

The reason I ask is that the RF12demo command processor is bare bones, injecting a string like that will force some sort of undesired response.
