Re: dmrtc headless mode


 

Hello Adrian,

Thanks for updating the docs.

I can confirm that -h works - stupid error on my side.

My trunk mode repeater is running for evereral days now and only once needed a restart for unknown reason.

Roaming between two tier II repeaters (DB0BR/DM0BT) here in Bayreuth and my Tier III repeater at home works flawlessly.

Registraration: ok

Talkgroup Attachment works. I programmed button TK1 with "Scan Group List" to get rid of annoying ongoing background calls if I want to talk on my selected talkgroup. Unfortunately, I cannot find any indication in the UI of the radio if the scan group list feature is on or off. In dmrtc, you can see additional TGs being subscribed once the feature is active.

I have make quite a few QSOs with a local OM working on a Brandmeister DMR repeater near Kulmbach - works flawlessly.

Private Voice calls: Had not yet had an opportunity for thourough testing. The terms OACSU and FOACSU are nowhere to be found in my CPS.

I did test a lot calling 9990 on brandmeister. I can say that this only works sometimes, but unreliably, and usually with very bad audio quality. weird.

SMS: No test yet. Try to send me one: DB9CR, my device is logged in most of the time I am at home in homeoffice.

Also the rest of the items still needs some testing.

I did have a chat with Ralph DK5RAS - he pointed me to

Seems to me that this could completey replace the ugly^h^h^h^hcreative :-) multi DMRgatway setup. Technically it's probably a SIP trunk with AMBE2 codec, but I did not have a chance to look at the relevant original DMRA paper (). Will try to dig deeper into this. Also, having a generic SIP implentation could make it possible to attach to an asterisk VOIP server - we have one here on db0bt.ampr.org in the HAMNET.

Hello Christian,

I've fixed all documentation bugs now hopefully, and also added a
troubleshooting guide based on our conversation.

Can you confirm that your below issue with headless mode does not exist when
using the "-h" option?
Also, it would be great if you could report which of the below features work
on your radio so I can add it to the radio compatibility matrix.

registration
talkgroup attachment
group voice calls
private voice calls (OACSU and FOACSU)
short text messages
call divert
voice with location
DGNA
status transfer service,
authentication
hunting in fixed or flexible channel plans
NMEA location polling via UDT

Best regards,
Adrian

Hello Adrian,

while dmrtc has a headless mode, it seems that still, a connection to an
X11 server is needed to start:

db9cr@tmo:~/software$ ( cd dmrtc/build ; DISPLAY= ./dmrtc )
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even
though it was found.
Hello Christian,
I don't see anywhere the "-h" option when you start it headless.
You can omit the DISPLAY variable when using "-h".
