DMR+ Dynamic Talk Groups

[NC9J]

Hi,

Is there a way to configure a DMR+ talk group as "dynamic" (or PTT activated) on the Pi-Star?

I found several articles about how to configure the DMR+ options like these:
https://0x9900.com/dmr-with-pi-star/
https://github.com/g4klx/MMDVMHost/blob ... options.md

In my experiments this afternoon, it seems that talkgroups configured in the DMR+ options are in fact static, and only the talkgroups listed in the options pass traffic back to the IPCS2 server.

Why would you want to do this, you ask? I would like to access a couple of talkgroups that are not available on my local repeater and that are not available on BrandMeister. But not all the time.

Thanks and 73,
Clay NC9J

On IPSC2 Network all Talkgroups will be on demand (dynamic) and are able to activate with PTT and are available up to 10 Minutes.
Only with Options= Parameter configured Talkgroups are statical booked.

In the world of DMR+ (at least in the uk) it depends on what master you connect to also.

No, the functionality of the static and dynamic talk groups is identical on all IPSC2 servers.
The static talkgroups can be booked on all IPSC2 with the help of MMDVM Options =.
If no options are sent, no talkgroup is statically connected.

The structure of the Options = line is as follows:

Code: Select all

Options=StartRef=4010;RelinkTime=30;UserLink=1;CQWW=1;TS1_1=262;TS1_2=110;TS1_3=1;TS1_4=20;TS1_5=0;TS2_1=2628;TS2_2=2627;TS2_3=0;TS2_4=0;TS2_5=0;

StartRef= 4xxx → desired StartReflector (4000 → no StartReflector)
RelinkTime= Time in minutes after which the StartReflector is connected again (after a manual change of reflector by user)
UserLink= Users are not allowed to switch reflectors (0) / Users are allowed to switch reflectors (1)
CQWW= CQWW Funktion opt-out / opt-in (0/1)
TS1_1= first statically booked talkgroup in timeslot 1
TS1_2= second statically booked talkgroup in timeslot 1
TS1_9= ninth statically booked talkgroup in timeslot 1
TS2_1= first statically booked talkgroup in timeslot 2
TS2_2= second statically booked talkgroup in timeslot 2
TS2_9= ninth statically booked talkgroup in timeslot 2


Please pay attention to the correct syntax and that between each parameter there must be a semicolon (;), also at the end of the line!
If TSx_x= is not used, please enter “0”: Example: TS2_2=0;

A maximum of 9 static talkgroups in timeslot 1, 9 talkgroups in timeslot 2, and a start reflector can be set at the same time.

Thank you all for your responses.

I found and fixed an error with the talkgroup rewrite rules on my Pi-Star. The traffic was going to the wrong timeslot.

I now see dynamic talkgroups on the IPSC2 status page like: xxxx (14) and my traffic is going through.

This is a cool feature.
