Analog_Bridge, one-way audio from DMR to ASL

Patrick Perdue
 

Hi:
In moving my DVSwitch to a local Raspberry Pi 4 rather than running it on the VPS, connecting to a remote AMBEserver, I'm running into a problem.

I now have audio going from DMR to USRP, but not the other way. It is bi-directional when running DVSwitch on the VPS.

Looking at the logs for Analog_Bridge, it doesn't appear to get audio from ASL, as there is nothing in the log when there is a transmission from Allstar.


In rpt.conf, I have:

rxchannel = USRP/0.0.0.0:34001:32001; GNU Radio interface USRP

In Analog_Bridge.ini:

[AMBE_AUDIO]
address = 127.0.0.1                     ; IP address of xx_Bridge
txPort = 31103                          ; Transmit TLV frames to partner on this port
rxPort = 31100                          ; Listen for TLV frames from partner on this port
ambeMode = DMR                          ; DMR, DMR_IPSC, DSTAR, NXDN, P25, YSFN, YSFW (encode PCM to this format)
[USRP]
address = xlx.borris.me                     ; IP address of USRP partner (Allstar/Asterisk or another Analog_Bridge)
txPort = 32001                          ; Transmit USRP frames on this port
rxPort = 34001                          ; Listen for USRP frames on this port


In DVSwitch.ini:

[DMR]
Address = 127.0.0.1             ; Address to send AMBE TLV frames to (export)
TXPort = 31100                  ; Port to send AMBE TLV frames to (export)
RXPort = 31103                  ; Port to listen on (import)
Slot = 2                        ; Export slot


Here is a full log from Analog_Bridge. During this period, there were several Allstar transmissions, but they didn't make it to the log. Only DMR is seen.

I forgot to mention that UDP 34001 and 31100 are forwarded through my local NAT to the Pi running DVSwitch.

in your Analog_Bridge.ini file turn your txPort and rxPort around.

txPort =31100
rxPort=31103

Hmm...

That doesn't make sense to me, because then the TX and RX ports match on both MMDVM_Bridge and Analog_Bridge. TX should go to RX of the other, which is how it is by default.

I did try it, which caused nothing to pass in either direction.

Hmm...

That doesn't make sense to me, because then the TX and RX ports match on
both MMDVM_Bridge and Analog_Bridge. TX should go to RX of the other,
which is how it is by default.

I did try it, which caused nothing to pass in either direction.

3138495, but not sure that it matters.

I have it working in both directions on my VPS, where Analog_Bridge is connecting to a remote AMBE server. The problem with that setup is Analog_Bridge likes to stop passing audio after a while, which is why I'm trying to set DVSwitch up locally on a Pi, and have it connect to a remote USRP/ASL, rather than using DVSwitch on the VPS, and relying on a remote AMBEserver.

The Raspberry Pi is behind NAT with incoming UDP port 34001, but nothing from ASL ever makes it to my Analog_Bridge. Outbound traffic from DMR to ASL works fine.

Here is what  I suspect (of course I could be wrong).  USRP uses UDP as its transport. 

If you are using DVSM, you set the mobile client to talk to AB on a single port.  This setting in AB (where TX and RX ports are the same) tells AB to use an enhanced protocol to talk to the client.  This enhancement is used to keep the NAT traversal path open to the client. The  trick is that AB  will send keep alive packets back to DVSM to tell the router/firewall that the NAT connection should be maintained.  As long as the keep alive packets are sent often enough the router will maintain the connection.

If you are using ASL as your USRP client to AB, you are using two ports  (TX and RX).  AB does not try to tell ASL to keep the  connection open (since ASL would not understand the keep alives).  So, if you are using ASL on a different machine than AB and there is a NAT between them, you will have problems.

Any of the above make sense?
Steve N4IRS
 

I'm going to suggest a alternative configuration.
Put your public ASL node on your VPS No radio interface needed. Setup a private node at your house. Add AB, MB etc. Setup a full time IAX connection between the 2 nodes.
Done...

Sounds reasonable. As I am moving soon, I'll set up an identical private node with a second AMBE dongle in another location, then just switch to that for the duration of downtime.

Partick,

I just wanted to say thank you!  I decided to go back and inspect the code for UDP encode and decode to a remote AMBE server.  What I found was that there was an error in the logic that was causing your AB to stop listening for new packets from the remote server.  I have fixed that error and when Steve releases a new build to github, I would love for you to re-test and verify that you no longer have to stop and start your AB instance on regular intervals.

However, the architecture that Steve pointed you at will also work and you may want to implement that anyway.  Your call.

Again, thank you!

Mike:

I'll probably end up implementing another instance of ASL, but testing that once it's available is easier in the short-term. So, I'll do that, too.
Steve N4IRS
 

I have pushed the update to Analog_Bridge for all architectures to github. <https://github.com/DVSwitch/Analog_Bridge>

So far, the new version of Analog_Bridge, connected to a remote AMBEserver, is working well. I've had it up for a few hours with a reasonable amount of cross-mode traffic, and it hasn't fallen over yet. Sometimes, with the old version, it wouldn't last an hour with heavy traffic. I'll report back if this changes.
