There are example LoRa sketches of polling remote nodes for information, see here;
Example 217_Reliable_Transmitter_Data_Requestor sends a request to node 123 asking for its GPS co-ordinates.
Example 218_Reliable_Receiver_Data_Requestor is run on the remote node and when it receives a request for node 123, it replies with the data.
Packets are protected by a 16 bit CRC and 16 bit network ID automatically appended to each packet so the chance of receiving corrupt data is remote.
Examples available for SX127X, SX126X and SX128X LoRa devices.

Myself, I wish Adafruit had not lableled the board in that way. It confuses people.
The RFM69 is one board, the RFM95 another seperate board.
But people seem to assume the RFM69 is a LoRa board and its not.

I have had some RFM69s on order for some time but our road is flooded so no post arriving!
I assume RFM69 modules can exchange packets similar to LoRa peer-to-peer

You would hope so. I cannot recall which FSK RF module they are actually based on.
But if you want to go FSK, the LoRa modules will do that as well.

Thank you so much for taking the time out to help me, I really do appreciate it.
@srnet
And thank you too.
I've got more than enough info now to get a handle on this... Although there maybe some questions further down the line
