YSF-N Ref. <-> NXDN Ref.: No continous transmission from YSF to NXDN #mmdvm_bridge


Stephan DG1BGS
 

Hi all,
We are currently playing different approaches to bridge our YSF Reflector with our NXDN Reflector. We have a working setup that bridges NXDN to our XLX Server which is also linked to the YSF Reflector. However, we would like to directly bridge the YSF Reflector and NXDN Reflector.

This is what our setup looks like (all instances running on the same server):


MMDVM_Bridge.ini
[System Fusion]
Enable=1

[NXDN]
Enable=1
RAN=1
Id=3227

[System Fusion Network]
Enable=1
LocalAddress=0
LocalPort=3200
GatewayAddress=127.0.0.1
GatewayPort=42000
Debug=0

[NXDN Network]
Enable=1
LocalAddress=127.0.0.1
Debug=0
LocalPort=14021
GatewayAddress=127.0.0.1
GatewayPort=14020


DVSwitch.ini
[NXDN]
address = 127.0.0.1
txPort = 35103
rxPort = 35100
fallbackID = 262034
nxdnFallbackID  = 3227
slot = 2
RemotePort = 6075

[YSF]
address = 127.0.0.1
txPort = 35100
rxPort = 35103
txWidePort = 35105
fallbackID = 262034
exportTG = 20421
slot = 2
RemotePort = 6073

What is perfectly working is NXDN to YSF. But when we want to transmit YSF to NXDN, the stream is not continuous. The NXDN side still kes up and shows the callsign, but no audio and all transmissions are being displayed with a duration of 0.5 seconds. This behaviour is also reflected by the MMDVM-Bridge.log:

Any help is highly appreciated.
