I have a couple of questions:
1: What type of bridges are experiencing the problem? Analog to
digital? digital to digital?
The default hang value is 2000 ms in Analog_Bridge.ini Which equates
to the minimum time presented to BM. A signal can not be less then
this value. This was implemented to alleviate the loop detector
Here is the default output from MMDVM Bridge:
I: 2018-06-06 01:57:23.512 DMR Network Parameters
I: 2018-06-06 01:57:23.512 Mode Hang: 3s
I: 2018-06-06 02:26:55.222 DMR RF Parameters
I: 2018-06-06 01:57:23.558 Call Hang: 3s
I: 2018-06-06 01:57:23.558 TX Hang: 3s
I: 2018-06-06 01:57:23.558 Mode Hang: 10s
I won't paste the default MMDVM_Bridge.ini but you will find that
the values already mirror the suggested values.
We appreciate your efforts, however since we already dealt with the
loop detector we could have helped trouble shoot this.

Try these settings for a way to deal with the
loop fixer on the BM Network. We have noticed it on a couple
of bridges & has solved the issue so far for us. Hope it
helps. 73 de K4SQI!

After much research and a chat with the BM Admins, I
have discovered the source of the problem for the blocked
All BM Masters run LoopBan. If the server sees 5 calls
shorter than 2 seconds over a 1 minute time, it will think
it is a loop and place a 10 minute ban on the call.
LoopBans are in place for 1 hour automatically.
With this in mind I went into the MMDVM_Bridge settings
and made a couple of adjustments to the settings:
RFModeHang=0 . changed to 10
NetModeHang=0, changed to 3
CallHang=0, changed to 3
TXHang=0, changed to 3
My thought process here is that if the 2 second mark is
key, just make all TX's at least 2 secs. So far today, I
have not seen the issues from before.
Just sharing my experiments for future reference.
