Re: Adding P25 to existing YSF and DMR bridge

Steve N4IRS

To get the bridge working, forget all the extra stuff to start. Tun off the reflectors, turn off the dashboards. Stop all DVswitch services starting at boot.
Start at one end of the bridge and work to the middle. If you don't see the traffic, stop and fix before moving on.

Start MB in the foreground. Is it logging into the master? Do you see traffic?
While MB is running, start the connected AB. Do you see the traffic?
Once you have this working, go from P25 in. Same thing, do you see inbound P25 traffic? Does the traffic transfer to the connected AB?
When that all works, cross connect the instances of AB.

When you post logs or config files for someone to look at, post them as separate files. That way we can open both files side by side, having to scroll up and down make it hard to troubleshoot. Same for the log files.

A little more background on my setup. I built this bridge using the DVSwitch-Server-RPI image as an experiment. However, I never ran the DVS script to configure for use with DVSM. I installed YSFReflector and P25Reflector on the same system. I'm using the original MB for my YSF to DMR bridge which works fine. I then added a second instance of MB for my P25 to DMR bridge. My original AB is configure for P25, and my second AB instance is configured for DMR. 

Everything is set to start at boot, and I recently added the new logs into the nightly logrotate process. I'm also planning to add the new instances to monit.

I just can't get the P25 to DMR bridge working and it is driving me crazy. I'm spending every free moment thinking about this and rechecking my settings.

Below are the log files for one transmission on the P25/DMR bridge side with my YSF/DMR bridge stopped..
