Yes, the example is the exact same I used. Only difference is I used HCW (and CW) on TX side, but only CW on RX side (in code didn't have HCW set to true). I only had one HCW version.
If you get the "......" on the RX side it is listening but not receiving any data. When it receives you'll get something along the lines of: "...... ABC [RX_RSSI: 56] - ACK sent........ ABCD etc."
Just checking your board is set to the right frequency, e.g. 433 or 915? (#define FREQUENCY RF69_915MHZ)
And you're using the hello-photon-rx-rfm69 example on the RX side, and the hello-photon-tx-rfm69 on the TX side? (Sorry, I'm sure you have all of this covered just trying to think of every possible angle.)
I'd prefer to keep everything Particle based but in a situation like yours I'd take a step back to linking up the RFM69 board to an Arduino where you know a larger community have confirmed the code. Start by just switching out the TX side to an Arduino (the example is based off the same example so the network ID, encryption key etc. is all the same). See if the RX then receives data. If still not, switch out the RX side to an Arduino to confirm your hardware setup/antenna/power/distance is all in order.
BTW, what does the TX side show in your serial monitor? Does it show that it is transmitting the data, but not getting an ack?
