Robby,
I checked and they both match...
I'm not sure what you mean by this. The DMR IDs both match between the radio and the node?
On the phone you indicated that the PTT on the MMDVM was not being activated, but the dashboard was showing a valid incoming call. Thinking about this further, you would need to be connected to a parrot node to receive anything back from a simplex hot spot, correct? (Sorry I've not configured may simplex radios. I've mostly configured full-duplex repeaters.)
To test the PTT functionality directly, Go to the MMDVM cal menu in Pi-star. More info here:
Use the spacebar to toggle the PTT on and off. You can also select various DMR test patterns to help tune the txinvert setting and the TX level.
You don't need to worry about the frequency or offsets since the MMDVM board is connected to an outboard radio.

?Robby,
Did you get my personal e-mail reply to your question yesterday?
Here is my response to you sharing your MMDVM.ini file screenshots:
------------------
Robby,
Try changing SelfOnly=0. If it is set at '1' it will only respond to a radio that has a matching DMR ID. If it is NOT set for self only, any DMR ID can access the node. I'm guessing in your case the DMR ID in your radio does NOT match the DMR ID (3190603) of the node.
This should at least get you past the "no PTT" hurdle. Once you have the board activating the PTT (and thus making the radio transmit) you can play with the TXinvert in the MMDVM screen and the txlevel pot on the board to get the node to successfully handshake with your radio.
