Welcome to DVSwitch

Hi Both,

I switched to the HB_Bridge branch and it performed a little better, in that hb_confbridge was relaying the frames to the parrot, however the parrot was still ignoring them.

I did some digging and found this was due to the fact that hb_confbridge was relaying the frames with the Radio_ID of hblink, rather than that of the Parrots 'client', so they were dropped.

I've resolved it by re-writing the RADIO_ID of the frame is being relayed to a master. I will submit a PR in due course, however I think I must be missing something as I'm surprised this hasn't picked up in the past. 

Is it unusual / unsupported for conf_bridge to bridge two Masters? 

Thanks

Hi all,

I'm trying to setup a basic parrot, which consists of the following-

hb_parrot (Master) - Provides Parrot Service

hblink (Master) - Allows clients to connect to the service

hb_confbridge (Client) - Conferences the two masters together, bridging audio from 'clients' to the Parrot

My MMDVM based hotspot has successfully connected to hblink, and hblink is relaying DMR frames to hb_confbridge, however they are failing client_datagramReceived RADIO_ID validation, as they are being recieved with the ID of my handheld rather than a client. I have verified this by adding an additional line of logging to hblink.py

I feel like I'm missing something obvious, or I've got my understanding wrong.

Thanks in advance,
Matthew

Mike,

Can I ask about the template file.  Back in time chatting to Cort, we discussed DMRlink having a template based system so adding more repeater manufacturers would be a simpler task, identify the strings required for each type got the template, group voice etc, and hopefully the Ambe data will fit into another manufacturers frame type.

The reason I ask is that I've gotten hold of a Hytera DMR repeater, and wondered if there might be some mileage in adding this to the types offered by DVSwitch?

All appears to be working, THANK YOU very much for all your help.  I have been looking for this functionality for a long time.  It beats putting a repeater in your car when you travel.

The template file is a requirement for creating IPSC frames from the bridge.  

Do I need the template.py file?  I can now transmit to the C-Bridge but not getting any audio.

Probably what I need is a listing of files for /opt/dmrlink/bridge and /opt/HBlink

In the short term I will make this a fatal error.  In the longer term, I will convert over to use the static values Cort was so kind to convert for me.
HB will not have the same problem since it does not use templates.

It goes in the same directory as IPSC_Bridge.py

Mike called it (what a surprise)

With template.bin
It works!

I found template.bin, does it go in the /opt/dmrlink/bridge directory?

Vance W6SS

wget https://github.com/n0mjs710/DMRlink/raw/IPSC_Bridge/template.bin

I do not have template.bin, where do I find it?

Coming to a screen near you

I have done some work on Analog_Bridge and DummyRepeater (AB and DR) that allow the passing of limited metadata between the two networks.  
On the AB side DMR IDs are looked up in the subscriberids.csv.  The call sign is then transferred over to DR along with the talk group and slot.  This information is placed in the DStar message field for the transmission so you can see the source call/tg and slot on your dstar radio.
On the DR side, the call is passed over the bridge to AB where it is looked up in the subscriber_ids.csv file.  If found, it is used as the source ID of the transmission for the DMR network.  If the call is not found (no cc7 id) then the gateway call is used instead.

I will make the changes available in the next day or so.

Mike

Than you, not having the rules files make it much easier.  Will wait what to find out from your testing.

Just to make sure, you *do* have template.bin in the dmrlink directory, right?
Can you look back at the start of your log for any error message like:

Vance,
I am chasing it now. Just to be clear:
hb_routing_rules are not used by basic HB to IPSC. Just HB_Bridge and IPSC_Bridge
It looks like this:
MMDVM <---> HB_Bridge <---> IPSC_Bridge <---> C-bridge

The only configuration files involved are:
HB_Bridge.cfg
hblink.cfg

IPSC_Bridge.cfg
dmrlink.cfg

You start HB_Bridge with "python HB_Bridge.py"
You start IPSC_Bridge with python IPSC_Bridge.py"

I am retesting the configuration now.
