Loss of DTMF Decoding PLUS loss of ability to edit ircddbgateway config file from Expert Menu

[dj5jd]

Hello folks

This problem is present again as of version 4.1.8.
The DTMF control no longer works in the D-Star.

Has anyone already found a solution?

Hi Folks:

Over the last couple of months, I have noticed that DTMF decoding on 2 of my repeaters has stopped working. This was a very convenient method of linking, unlinking, etc., when mobile. If it matters, the two systems that have lost the dtmf decoding capability are both running the Repeater Builder STM32DVM v3 Board (USB connectivity).

I have another 2 systems running the Repeater Builder STM32DVM Pi Hat Board, and DTMF decoding continues to work on those two systems!

I was going to attempt a f/w update on one of the USB boards yesterday, but the latest f/w seems to be v4 (at least per the instructions on the RB site): https://www.repeater-builder.com/produc ... USB_v3.pdf

Has anyone else experienced this loss of DTMF decoding issue, or have a solution that I can try?

Thanks,

Hi Folks:

Here is a bit more information in case it helps...

VA3PMO running Pi-Star 4.1.6 / MMDVMHost_20240210_PS4 --> DTMF no longer working

VA3DVI running Pi-Star 4.2.1 / MMDVMHost_20240210_PS4 --> DTMF is working

VE3RSD (this is a two module system, the Gateway and one of the modules is on VE3RSD B and the 2nd module is on a second Pi, VE3RSD C):

VE3RSD B running Pi-Star 4.1.8 / MMDVMHost_20240210_PS4 --> DTMF no longer working

VE3RSD C running Pi-Star 4.1.6 / MMDVMHost_20240210_PS4 --> DTMF is working!!!


This last one is puzzling... I changed the parameters in the hidden Remote Control file (and re-booted) and that doesn't seem to make a difference, DTMF works regardless, so I am under the impression that the DTMF decoding and communication with ircddbgateway is being performed via some other means.

The other common thing between VA3DVI and VE3RSD C is that these two systems are running the Pi-Hat version of the Repeater Builder STM32DVM board, whereas VA3PMO and VE3RSD B are running the USB version of the same board.

Any ideas?

OK folks (if anyone is reading this!)...

The 2 systems that are successfully decoding DTMF are both simplex hotspots. The 2 systems that are not decoding DTMF are full duplex repeaters.

So, on one of my repeaters, I just changed the config in Pi-Star to make it a simplex hotspot... and voila, DTMF decoding works!!

Hope this now allows someone to look into the issue.

Hi Folks:

Not seeing any traction or even response to my posts about the loss of DTMF on full-duplex installations, I reached out to Jonathon, G4KLX to see if he was aware of the issue and if a fix was in the works. He mentioned that he was not aware of the issue and I was told to use "normal support channels" to report the issue.

If this forum is not one of the "normal support channels" can someone please enlighten me as to how to report bugs (or issues)?

Thank you.

Anyone heard something more about this issue ?

Does it work now ?

My D-star hotspot is running a 4.3.0 beta (probably the older before respin #1) and it's a duplex hotspot.

Maybe I should downgrade to 4.2.1 ?

It was made known yesterday the developer of mmdvmhost created stricter rules to the way mmdvmh handles dtmf codes. That change was undone yesterday by him and given upstream changes are automagically implemented by the pistar server within the overnight updates this issue 'should' now be fixed.


For those that dont run their installs 24/7 youll need to run a manual update so you get the new code changes made to mmdvmhost.

Hi Andrew!

I have several Pi-Star enabled repeaters and would love to get DTMF functionality restored. My systems are all on 24/7; I have also tried to manually update them, and on one system, installed the new 4.3.0 image and applied updates. DTMF decoding is still not working. Am I missing something? (as previously reported, DTMF works on simplex hotspots but not on full-duplex repeaters).

Thanks,

klx mentioned in one of the groups he had made changes to mmdvmhost which tightened up the dtmf feature to help with fast data modes. That change was undone by him the day prior to my posting above. The change was pulled into pistar the morning of that post.

I dont know what to tell you at this point, the changes were made and the updates pushed via the nightly auto updates.

Hi Andrew, yes, I brought this to Jonathan's attention in July of 2024; he advised that I should be reporting it via one of the established support channels. I believe I first reported it here much earlier than contacting him. Regardless, DTMF decoding has always worked in simplex mode; I just tried it this morning on my new repeater build (with Pi-Star v4.2.1) and DTMF is still not working in full-duplex mode. My Repeater Builder STM32 MMDVM boards are all running at 460,800 baud. Given the other benefits / features of Pi-Star, this is not a show stopper for me, but more of an inconvenience.
