I had issues with mine, describes here:

What firmware version are you using?


Re: ASL to DMR Bridge...changing talkgroups

Dan K0TI,
Thanks for this info.  I just got the Allstar to DMR Bridge setup and it's working great.  Very easy to change talkgroups using DTMF commands, as described above.

Take Care!

Re: hytera USB packet structure

The BPTC function in dmr_utils3 has at least the last 2 bytes commented out. I'll send you a function for what I have in the next day or so.


Re: hytera USB packet structure

Thanks, I'm happy to privately send a GPS packet if it will assist either of us. maybe HBLink could support radio data directly in the future, sound like it could be a case of just listening and responding on a few UDP ports.

I do not have a PiStar, MMDVM etc. Just a standard hytera radio with 'forward to PC' enabled.

I am familiar with dmr_utils3 as I happen to also be writing my 'connector' in python, however am yet to incorporate it into my packet analysis. The initial 9 bytes do appear to align correctly. Hopefully a job for tonight.


Cloud based Dstar Ambe Server Audio Quality

Ken, K6EFJ
 

Does anyone in the group have experience using Zum Ambe Server on a Cloud based VPS? 
I currently have a working Debian 10 (Buster) cloud based (Wireblade VPS) install of DvSwitch Server and Allstar.  I have a public facing Zum Ambe Server on a separate fiber to home connection. Dvswitch is configured with the correct IP address and port number for the ambe server, but the audio quality on Dstar is very poor. If I switch to MD380 emulation in DvSwitch Server it actually sounds better. I have a second duplicate installation (same fiber to home connection) of Dvswitch Server and Allstar (2-14 image) on a Rpi 3b using a NW Digital ThumbDV or a DVMEGA DVstick 30 and the audio on Dstar sounds great. I have already tried swapping the Zum Ambe Server and power supply as I have two of them with no difference in results.  Any ideas????

Re: hytera USB packet structure

Eric - KF7EEL
 

I haven't seen a Hytera GPS packet, but would like to as I may be able to add it to hblink for decoding. All the data types that I have seen have been at 1/2 rate, so BPTC works. When I started investigating a few months ago with wireshark, all the DMR data was encapsulated in an MMDVM packet. I was sniffing traffic from my hotspot to try to decode GPS data. When I finally got something figured out, I built an application for hblink that decodes the data (BPTC, happened to be built into dmr_utils3 python library).

I have seen data from Anyone, TYT, Motorola, and a few others, all encoded at 1/2. Setting SMS settings on my Anyone for H-SMS (believe that is for Hytera) results in SMS encoded at 1/2.

I am guessing that the data you seek is encoded at 1/2 rate. You can enable a setting in PiStar to all least decode the packet header, that would point you in the right direction.

There are also a couple lines in my hblink fork that you can uncomment that will display the raw decoded packets.

Thanks Steve,
Unfortunately no-one here seams to be able to help and as it wasn't a DVSwitch question I wondered if there was a more appropiate place to ask.

I'm just looking to document a couple of DMR packet structures and put them on Github for everybody.

Re: Analog_Reflector VPS

Peter,
Are you trying to add Analog_Reflector to your existing AllStar to DMR bridge or building a new bridge?

Re: hytera USB packet structure

Kev
 

Hi Eric, If you are more familiar with GPS Packets, have you seen a hytera one? Could you tell me the data structure?
I might be miss reading it, but currently I don't see the etsi format of 3+25+24 bits.
I do see a 'N' and a 'W' but the numbers between don't match. Maybe two's compliment?
Thanks
Kev

very good, thanks for all the information. Good continuation in your development.

Re: hytera USB packet structure

Kev
 

Hi Eric, thanks for taking the time to help.
Could you have a quick look at my attachment? you might recognise something there I've missed.
GPS is my next protocol, I have captures of that too.
I believe these are standard etsi packets, I think I've just read too much etsi and confused myself :)

These where captured in hex using wireshark. The USB is recognised as a network adapter.

As root:

apt update
apt upgrade
if any updates applied, reboot
wget http://dvswitch.org/buster
chmod +x buster
./buster
apt install dvswitch-server
apt-install analog-reflector
logout
login
run dvs to configure DVSwitch Server
edit Analog_Reflector.json to configure the reflector

Re: P25 to DMR on VPS Server

Thanks for the reply's everybody

 

I'm not familiar with DVSwitch and need a guiding hand to help me set this up. Can someone point me in the right direction to getting this P25 to DMR setup?

Which parts of the repo do I need and what settings should I be aiming for?
