Re: ASL to XLX in DSTAR mode ? MMDVM_Bridge transmitting DMR-ID instead of callsign

Like Steve N4IRS says, make sure that the subscriberFile in Analog_Bridge.ini points to a valid DMR ID file. Here's what I use:

Here was my mistake : MMDVM_Bridge was pointing to a valid dmd-id file, but Analog_Bridge was not. Doing so, the right callsign is now displayed in the outgoing D-Star frames.

Anyway, XLX still seems to ignore those frames. It just displays :
Jan 16 20:48:52 xlx xlxd: DCS packet (100) from 10.44.0.3
while it should display something like that :
Jan 16 20:40:20 xlx xlxd: Opening stream on module K for client TK1BI   B with sid 41964 
I'll have to investigate on the ircddbgateway and XLX side...

Re: Bridging a P25Reflector and a YSFReflector?

Steve N4IRS
 

Loop (TX to RX, RX to TX) the YSF and P25 ports in DVSwitch.ini
[P25]
Address = 127.0.0.1
TXPort = 34100
RXPort = 34103

[YSF]
Address = 127.0.0.1
TXPort = 34103
RXPort = 34100

Enable YSF and P25 in MMDVM_Bridge.ini
Setup Networking for both modes in MMDVM_Bridge.ini
[DMR]
Enable=1

[P25]
Enable=1

[System Fusion Network]
Enable=1
GatewayAddress=ysfreflector.dvswitch.org
GatewayPort=42166

[P25 Network]
Enable=1
GatewayAddress=127.0.0.1
GatewayPort=42020
LocalPort=32010

YSF points directly at the YSF reflector address and port
P25 requires P25Gateway. Set the Startup= to point at the P25 TG you want. If the P25Reflector you want is not in the P25Hosts.txt file. add it to the private host file.

Re: Decoder error

Jeff Lehman, N8ACL
 

I'm sorry I lied. My fat fingers on my phone. The error is "Emulator timed out on encode!" in the Analog_Bridge.log. This causes the ASL node to just loop on  a key and unkey cycle every 2-10 seconds and won't receive DMR after that.

Like Steve N4IRS says, make sure that the subscriberFile in Analog_Bridge.ini points to a valid DMR ID file. Here's what I use:

; Metadata management
subscriberFile = /var/lib/mmdvm/DMRIds.dat      ; DMR ID to callsign lookup data
exportMetadata = true                           ; Export metadata to USRP partner (transcode setups require this)

That solved the issue I was having.

Re: Help linking P25 to DMR

Thank you Steve - it's working now! The last sticky bit is that the MMDVM_bridge connection to the BM master times out repeatedly, about every 2 minutes. This happens on BM master 3103 and 3102. Any thoughts on this one? Thanks again!

Re: Help linking P25 to DMR

Steve N4IRS
 

Mike is correct. Analog_Bridge_DMR communicates with DVSwitch.ini DMR Stanza
Analog_Bridge_P25 communicates with DVSwitch.ini P25 Stanza
You can not use the same ports.
I suggest you use the default values in DVswitch.ini and match the instance of Analog_Bridge to match it.

Also,
In Analog_Bridge_DMR.ini you can not leave the gatewaydmrid and repeaterID to 0. Set them to real values.

Yes you will need those things also. here is a basic diagram:
P25Reflector <-> P25Gateway <-> MMDVM_Bridge <-> Analog_Bridge <-> Analog_Bridge <-> MMDVM_Bridge <-> DMR Master (BM, HB etc)
You will need 2 instances of Analog_Bridge
The 2 MMDVM_Bridges can be done as one instance.

The question is, what exactly are you trying to bridge? That will tell us more about the ends of the bridge.

looks like you are using the same ports on DMR and P25. they have to be unique.

As a point of reference I am currently transcoding the following things over to ASL on a single RPi3B+

NXDN -> md380emu -> Analog_Bridge -> ASL
C4FM -> md380emu -> Analog_Bridge -> ASL
DMRLink -> IPSC_Bridge -> HB_Bridge -> hblink3 -> DV3000 -> Analog_Bridge -> ASL

Note that each "ASL" above is a separate "node" within the same ASL instance on the RPi and that the system load is minimal (all three are active at the same time when a transmission is made).

I want to do the same thing P25 31555 currently up and running. And 31555 DMR brandmiester. The same question is the RPI 3 plus robust enough to run this cross link?
