Hi Steve,

Did it turn out to be a case of "Computers Says No" ?

Bug fix and other changes.

Steve N4IRS
 
Edited

Over the last few days, Cort identified a bug when OpenSpot was communicating with HBlink / HB_Bridge. Mike created a fix that has been tested and looks like it solves the issue. I have uploaded the change to the dmr_utils repository.
I suggest people do a git pull on the dmr_utils repository and then run the install.sh script. Please report here any issues you encounter. We would rather not have to chase down people experiencing a problem without reporting it to us.

Cort has decided a simplification of the repositories are in order. We will be moving some of the older, unused or superseded applications into a separate directories. This should alleviate some of the confusion new users are experiencing.
We will be making some changes in HBlink to better align it with the structure of DMRlink. In simple terms, reducing the number of small sub applications (my term) required to bring up a HBlink application. As we move forward there will be a effort to create a more unified environment.

Mike and I spoke about the issue that require people to use DMRGateway as a "shim" between HB_Bridge and XLX. We think this can be resolved with a pull request to the XLX repository. Stay tuned.

Matthew, this is the carrier board if you've not seen one, its a USB to serial converter.

Steve - The DVMega AMBE3000 initially came out as a 'shield' that would sit on an Arduino, with an additional audio board so you could plug in a mic / speaker and hold a QSO over a D-Star(?) network via a PC without any local RF.

The next evolution was the 'carrier board' which  removed the requirement for the Arduino , and meant you could plug it directly into a PC and use the PC sound card rather than the additional audio board + Arduino.


Peter - does it look like the carrier board is doing anything other than converting USB to serial?  If not, then hopefully Analog_Bridge can interface with it directly. If there is an additional microcontroller it might be best going straight into the AMBE3000 with a serial adapter

Cheers all for taking an interest in this, much appreciated.

What is the port name for the serial device?  /dev/ttyUSBx, /dev/ttyAMA0, something else?

It was sitting on an Arduino MEGA, I also have the carrier board.

Hi All,
Guss got back to me and confirmed-
The ambe board is designed to communicate accordingly to the DVSI spec.
So hopefully it can be made to work. 

Out of curiosity Peter, were you interfacing with the AMBE directly via serial, or via the carrier board? 

Cheers

I did try yesterday to communicate with Peter's install at both 115200 and 230400. I was unable to communicate. I "assume" since it was on USB1 it was the carrier board.
We need to do more looking at DummyRepeater since it supports both the ThumDV and Guus board.

Steve,

Yes no problem, I can plug it into the same box as the the current 3000USB >asl.

I'll set it up and send you the details for you to have play tomorrow.

If it's untested, what does the AMBE3000 board need to expose to Analog_Bridge in order to work? The raw serial interface from the AMBE chip?

Thanks for confirmation Peter. 

You never know, Guss might be interested in putting in an analog_bridge mode if only minimal software changes are required.

Cheers both

DMRLink and HBlink repositories.

Steve N4IRS
 

Over the last week or so, we have noticed a few misconceptions in the structure of the repositories. GitHub allows for multiple branches in a repository. In the case of DMRlink, when you look at the https://github.com/n0mjs710/DMRlink you are looking at the master. For the most part in a perfect world, the master should be pristine. What I mean to say is changes are rare and should be vetted before they are applied to the master. When we want to do a bugfix or add a feature, we add a branch. The new branch starts out as a clone of the master. From there, we start making changes, additions etc. This way people can use the Master branch with some certainty that the code us not changing under them. Every change that is made to the new branch is tracked against the master. Once we have tested the changes and are happy with the results, the changes are merged back into the master. Two things to understand, nothing requires repository management HAS to be done this way and my explanation is rather simplistic. Since the new branch was cloned from the master, it's possible that more then one program has been changed or added. The thing to remember is that within a branch, everything is supposed to work together.

When we built HB_Bridge and IPSC_Bridge, that was the case. The new branches started as a clone of the master. Programs other then HB_Bridge and IPSC_Bridge may have been changed. With out looking at the "commits" or doing a compare of every file within the branches, you do not know what your are going to get. For that reason, you should checkout or "clone" the complete branch. Do not pick and choose from multiple branches. Yes, it MAY work, or it may not. Troubleshooting a mix and match of multiple branches can be time consuming and frustrating. If you want the bug fix or feature of a branch, clone the whole branch. For example to clone the IPSC_Bridge branch of DMRlink, at the Linux command prompt "git clone -b IPSC_Branch https://github.com/n0mjs710/DMRlink.git YourDirectoryName" This will download the IPSC_Branch into a new directory called "YourDirectoryName". You are now assured that the programs work together. IPSC_Bridge.py depends on dmrlink.py etc.

We have held off merging the HB_Bridge and IPSC_Bridge branches back into the master branch. Since these were significant changes, we wanted to wait and debug before the merge. We will start merging soon so that we can start simplifying and adding features.
