Re: DVSwitch Client does not receive

Steve N4IRS
 

Gareth,
Do you have pyUC connected to the server while you are trying to use the Android client? Since you have setup pyUC are you sure you are using the same UDP ports for TX and RX as you are in pyUC?
Check the Analog_Bridge log in /var/log/dvswitch. Any errors?

Hi All, 
I’m really hoping someone in this group can help me because I’m tearing my hair out. 

I’ve followed every version of the instructions I can find, every tutorial on YouTube yet I can’t make this system work.

ok so firstly I have DVSwitch server running on my Raspberry pi. It works - it’s connected to brandmister  no problems, I can connect the pyUC client via my Mac or PC and that works and I’ve even had one short QSO to the USA.

then we come to the client program on android. I’ve loaded the latest version on to my brand new t320 network radio from Moonraker. I’ve set it up as per the instructions.

and this is where it all goes a bit screwball.

the switch server sees the client, I can change talk groups, if I press PTT the servers diagnostic webpage shows PTT and if you enable the RX monitor function on the servers webpage I can hear my voice.

but…. Receive doesn’t work on the client. The Server is getting traffic, as I’ve said above but nothing is going to the DVSwitch client, it doesn’t show anything on screen, no indication of traffic, no receive audio nothing.

I am at a total loss . Can someone help me please.

many thanks Gareth GM0WUR

While installing pip3 install pyaudio I get errors, I don't know what information you need from me to help troubleshoot, so I'm just going to give you some basics and hope it enough.

Re: Trying to install and setup DV switch on android

You made backups of the files before you modified them. You can restore the backups if you have a problem. Since you are running ClearNode, I would contact Gerry from ClearNode since he overwrites the config files from templates. I sent him the info months ago so that he could incorporate the changes needed into the templates.

Re: C-Bridge -> HB-Link using HB_Bridge & IPSC_Bridge.

Will,

It was after an update.  Now running 9831.2021.1.10.  Tried to go back to a previous version from January 2019 with same results.  Its just strange that I am running the same issue to playback.py using only DMRLink.

Steve,
I will ask in that group.

Thanks.


Re: Noob, wishing to tap into the wisdom here

Wow, so encouraging! Thanks.

Ok, so I do have a ThumbDV, I just referred to it by another nomenclature.              <joke class="obscure"> does it have an NSN? </joke>.

Also, fortunately, I did buy a really good DMR HT before realizing that I need something that does the other 'stuff' digital. So I can operate for a while with DMR function waiting until later.

So, This tells me what I need to do is get all this fired up and running so I can start to interact with y'all on the level you are familiar (acronyms and such).
Let me dive into it and with the confidence that it is not wasted time and see how it goes.

Glad to hear the FT-8900 will work. I have a couple of radios that do narrow, but their ability to TX/RX wide data is questionable. If using the data port and the 9600 baud pin on the FT-8900 is sufficient then that will help.

No one, yet.  And AFAIK, I don't know anyone with plans to do DMR.  Currently, only M17 is the focus for the client.

The basic idea will work for all modes except DMR.  In fact, there now exists an implementation that uses a MMDVM modem (can use a hotspot board for QRPP) into a 9600 bps capable radio.  Currently, this sort of modem only exists for M17, but other modes could conceivably be added.  Some modes (especially D-STAR) would also require a hardware AMBE vocoder, such as a ThumbDV.  DMR deserves special mention, because of the T/R switching requirements for proper repeater operation, as you alluded to.

Hey guys (gals), 

I have a desire/dream to build a device wherein I connect a UHF FM radio & antenna to, an interface board, a Raspberry Pi, and then some sort of spkr/mic/PTT arrangement that will allow me to TX/RX in the 3 major digital protocols (DMR/D-Star/YSF), all from the same setup.
I do not expect to do all these at once. Even if I had to reboot the device to switch modes, just as long as it could do all 3, that would be fine.

I have the 
STM32_DVM_v4, a Pi 3 B+, and one of those DV300U USB sticks from NWdigitalradio.com

I have been a software dev/dev-ops/tech svcs worker for over 20 years.
I have both mocked people who say it, and also said myself,  "It can't be that hard." 

Can you point me in the right direction in this group?

The basic idea will work for all modes except DMR.  In fact, there now exists an implementation that uses a MMDVM modem (can use a hotspot board for QRPP) into a 9600 bps capable radio.  Currently, this sort of modem only exists for M17, but other modes could conceivably be added.  Some modes (especially D-STAR) would also require a hardware AMBE vocoder, such as a ThumbDV.  DMR deserves special mention, because of the T/R switching requirements for proper repeater operation, as you alluded to.

There was an announcement abour M17Client on the OpenDV group.  I've been testing M17Client with a Repeater Builders MMDVM modem and a Yaesu FT-8900 with great results.  I have been using this with a MMDVM based repeater that I have on test here.

Hey guys (gals), 

I have a desire/dream to build a device wherein I connect a UHF FM radio & antenna to, an interface board, a Raspberry Pi, and then some sort of spkr/mic/PTT arrangement that will allow me to TX/RX in the 3 major digital protocols (DMR/D-Star/YSF), all from the same setup.
I do not expect to do all these at once. Even if I had to reboot the device to switch modes, just as long as it could do all 3, that would be fine.

I have the 
STM32_DVM_v4, a Pi 3 B+, and one of those DV300U USB sticks from NWdigitalradio.com

I have been a software dev/dev-ops/tech svcs worker for over 20 years.
I have both mocked people who say it, and also said myself,  "It can't be that hard." 

Can you point me in the right direction in this group?

Thanks
