MMDVM_HS_HAT_DUPLEX DMR not working

[AB8PR]

I have an MMDVM_HS_HAT_DUPLEX that works in all modes except DMR.
It has firmware v1.5.2.
For the modem, I have it set to the STM32-DVM / MMDMV_HS - Raspberry Pi Hat (GPIO).
I also have a ZUMspot that works perfectly on DMR and I have the exact same settings for both for the DMR configuration.
Any suggestions would be appreciated.

Try using this modem setting:

MMDVM_HS_Dual_HAT (DB9MAT, DF2ET & DO7EN) for Pi (GPIO)

To flash this it is normal to need the BOOT1 jumper shorted, there is usually a PCB pad you can solder across.

Hmm, the STM32 used to have a Duplex setting that seems to have gone away in one of the latest updates, since I am 99% sure that is what I was using as thats what I have.....looking now, it is set the same as what you have, and its working just fine in duplex.....I only use DMR....GL!

The duplex function works fine for all the other modes (D-Star, YSF) with this modem selected.
All the DMR settings are correct. As I mentioned, the DMR settings are exactly the same as my other hot spot and it works properly.
It just doesn't seem to hear or transmit DMR at all.

I changed the modem to: MMDVM_HS_Dual_Hat (DB9MAT, DF2ET & DO7EN) for Pi (GPIO). Still no DMR.
I changed my ID to the other one I have (different from my other hot spot) and still no DMR.
However, before when I keyed up, I got no repeater found tone.
Now I get a connect tone, but still nothing shows up in the dashboard.

Frequency offset perhaps?

[AB8PR]

I did the frequency calibration. Still no DMR.

I did the frequency calibration. Still no DMR.

You could open a separate live log tab and see what appears in the log window there.

[AB8PR]

Absolutely nothing appears when I transmit on DMR.
When I transmit on D-Star, I do get log entries.

Also, when I ran the calibration, it did transmit and I was able to hear the test tone on my DMR radio.
When I transmitted from the radio, the hot stop did show it heard my radio and reported BER error rates, etc.
So, why isn't it connecting?

[AB8PR]

Nope, that's not it. The radio ID matches the Pi-Star and the ID is correct.
