Bridget - a MMDVM Portal to PNW DMR

 

 

Important Notice:  The one-way problem has been identified and a fix is in the works, time permitting.

We now have official help from THE Huckleberry.  So some testing will be done over the next few days to address the one-ways.  Intermittent working of Bridget 2 is likely.  Local 9 should be working fine for Intercom style conversations.

If you wish to help on this project and you are fluent in Python, web apps and/or websockets, please see more details on the install page.

Notice:  Bridget has issues with a one-way mode.  c-Bridge to openSpot will stop passing traffic, openSpot to c-Bridge always works.

We have settled on our talkgroup deck for now.  It is a blend of too many and not enough for a single timeslot so we may adjust it slightly as we have more user activity.  MCT off will be available if you wish to turn off the full time talkgroups.  Local 9 is the openSpot intercom talkgroup to all clients connected to Bridget and it holds off the c-Bridge talkgroups.

Bridget will be switching to PNW members use only soon, so check out the Yahoo Group Bridget Files if you find that you are not able to connect.

***  CUSTOM SERVER  ***

  1. Do you want your create your own MMDVM server? 
  2. Do you want to be able to use your openSpot or other MMDVM client to connect to your MotoTRBO repeater or c-Bridge peer manager?
  3. Do you want to use your own talkgroup deck?
  4. Check out our set-up page.

NOTES

We have added a new zone to the PNW CS-580 codeplug to support Bridget.  It also sports RS Groups on 3 channels.  Most users are likely to just listen via promiscuous mode.

openSpots only support a single timeslot, so even though some of the PNW talkgroups appear on timeslot 2, simply ignore that and use the single timeslot mode on the openSpot and program your radio for timeslot 1.  Bridget handles the routing to the correct timeslot on the c-Bridge as well as the reverse.

When you connect the Bridget server, you appear on the c-Bridge as if you were using a repeater named Bridget oddly enough.  Use NetWatch to see the activity.  All talkgroups have hold-off timers as shown above so remember that if you ker-chunk one you are turning off many others.  You should ker-chunk again if you wish to listen to a different talkgroup or otherwise wait the typical 2-3 minutes for the hold-off timers to toll.

Local 9 is a valid talkgroup for openSpot users or other MMDVM clients.  It enables users to talk to other openSpot users similar to an Intercom.  Hold-off timers are set to 2 minutes, shorter than normal (really the priority is to get into the PNW network) but long enough not have the c-Bridge activity barge into your active conversation.

If you key up on a talkgroup not active in the Bridget TG table, your activity will still show up on NetWatch but the activity will go nowhere.  You will see "Unresolved" with the talkgroup ID number if that is the case.  If this happens, no hold-off timers will be activated and all c-Bridge traffic will still be active back to the openSpot.

When setting up your openSpot, be sure to have advanced mode" mode checkbox checked so that you can enter the server IP and UDP port into the fields and then chick Add Server (see image).  Also, be sure that  for "DMRplus options for DMRplus" setting does NOT have the "Use DMRplus options" checkbox checked (see image).

The Bridget project is in motion and the talkgroup deck may change so check back here fore the latest information.  BTW, Bluestack devices are not supported.


UPDATES

8-8-17:  The talkgroup deck programming is complete, MCT Off is now optionally needed as this manager is now with fully coded hold-off timers for all listed talkgroups above.

8-7-17:  B 2.0 is now working solidly so will begin to expand the talkgroup deck.  OR 1, WA 1, WA 2, PNW 2 and PNW Regional 2 are fulltime to enable Bridget listeners to have something to monitor and maintain some connection to our network.  The plan is to take Bridget private and available only to PNW members and other closely affiliated hams with interest in the project.  Publishing the Bridget how-to will enable other groups to create their own portals.

8-1-17:  Local 9 will be the default openSpot to openSpot intercom talkgroup.  This talkgroup tends to be used by most openSpot users for the server annunciation as well as redirect.  Also channel redirect can be used with Bridget.  So be sure to turn redirect off when switching your server to Bridget if you have the correct talkgroups programmed into your radio.  Also you can simply use redirect but with the correct talkgroup deck as listed above.

8-1-17:  Added the set-up Information to this page.

7-31-17:  Bridget 2.0 is out of beta.  Washington 1 has been added to the deck.  "Unicom" is on PNW Local 1 for all openSpot user connections if they wish to chat openSpot to openSpot. 

We will publish everything soon on how to set-up your own portal.  A test run this morning had a working install up in 7 minutes once the VPS was ready, all done by scripting.  Just 3 simple config files to adjust to your own installation and done.  Again Vance, W6SS has been the lead on getting the major work done to get to this point.  We ultimately hope to be able to handle multiple talkgroup decks going to different c-Bridge managers and different c-Bridges, all from the same VPS (keeping costs to a minimum).  The original servers 1 and 2 will likely go away at some point soon.

7-28-17:  Bridget 2.0 is out!!!  The same TG's are available.  This new VPS is utilizing a variation of the setup used on Bridget 1 and 2 and appears to be bullet-proof.  At least at this early point, all is looking good. 

This implementation was created with the great assistance from Vance, W6SS.  He deserves much credit for providing the assistance here as well as the training needed to manage and re-create the installation from a fresh VPS spin-up (Debian 8.9 x64).  We intend to publish the details and make it relatively easy to deploy this project for other c-Bridge owners or repeater owners who want to supplement their own repeater managers with openSpot or other MMDVM clients.  More to follow...

7-10-17:  Server 2 is now on 52032 and normal comms have been restored.

7-6-17:  You may wish to update your openSpot to Firmware v0119.  I had a report this morning that the user had not been able to connect when using v0117.  But on the other hand, I've not had any issue with connections while using v0117.  If you are using older firmware, this may be helpful generally as well.  YOUR MILEAGE MAY VARY!!!

7-2-17:  UDP changed on Server 1 from 62031 to 52031, Server 2 (62032) is unchanged.

6-28-17:  Local 2 works fine for openSpot to openSpot users, had a 4 way tonight.  But still some issues overall, so be prepared, this is still in beta with more fixes and changes to come...

6-27-17:  HEADS-UP:  The UDP Ports on Server 1 will be changing to 52031 and Server 2 may be 52032 soon.  If you can't connect, try these also (once you see the setting have changed below).  This is in part, to address those hams who are not able to connect under any conditions on the higher ports.

6-22-17:  62031 Only:  Experimenting with call complete determination timing.  Default is 500 ms (150-1000), first week was 500, now at 150 ms, will extend out to 1000 over some time.  Comments welcome.


The servers below are still operational but also likely in one-way mode and not useful.  A decision to abandon this setup will be determined later.

This particular project has been in the works for months but is based on the great work of multiple folks going back 4 years or so.  All software is open-sourced and available on GitHub by N0MJS.  Also kudos to and for the fine assistance of Corey N3FE, one of the USA Brandmeister admins who has shepherded our efforts at PNW DMR.

The software/packages used are:  dmr_utils, dmrlink and hblink
Currently running on Debian 8.8/64 at DigitalOcean SFO, 1 core.
