Glad to hear Steve.

Off to order a board.

Re: 6 Channel USB AMBE Transcoder Kickstarter Has Started

 

Chris,

What application are you using with AMBEserver?

The ambed server (an AMBE server) for the XLX system handles stream management for a multi-stream application.

I cannot say when other applications will adopt ambed, or if AMBEserver will be modified -- however, both server applications are fully open source for application developers to connect.

My caution is that this Kickstarter is only 30 days, and the XCode-3006 is dependent on reaching the funding level, Talk to your application developer and see what their plans are, but the only fully tested application to this point in is the XLX reflector combined with ambed.

I am pleased to announce the launch of a Kickstarter for a 6 Channel USB AMBE device which is compatible with the XLX Reflector System.  The XLX system creates reflectors for the DCS, DExtra, and DPLUS systems and also supports integration with DMR.

To transcode AMBE+ (D-STAR) and AMBE+2 (DMR/YSF/dPMR/NXDN/P25-Phase 2/...) requires a hardware solution.  This can be accomplished using pairs of ThumbDVs or other USB based AMBE-3000 devices. 

Reflector systems may have multiple reflectors (A-Z) that require transcoding simultaneously, which requires multiple streams available and that is where the XCode-3006 comes to the rescue.

The folks behind the XLX system designed a board that can provide up to 6 streams on a single USB port and it is in operation now at XLX950 (XRF950/DCS950/...) which is using the board to cross connect with DMR.

NW Digital Radio is running a Kickstarter to fund an initial build of 50 of these units. 50 units is the minimum production run in order to keep costs down.

This is where you can help:

If you run a reflector, you can obtain a XCode-3006 via a pledge on the Kickstarter at one of two levels.

If you use a reflector, you can help the operator of that reflector by helping them obtain a XCode-3006 via the kickstarter.

If you just like the idea of a six channel AMBE transcoder, and want to help out, there are pledge levels for supporters like you.

This can only happen if we meet the funding goal set for the Kickstarter, and we only have 30 days to reach it.

Having this board available opens the opportunity for other projects such as:

Analog <--> DV Gateways (eg. Allstar, Echolink, ... to your favorite DV system)
DV --> Analog Streaming for online monitoring of DV systems
...

Newbie needs info on getting on d-star

Larry Herzog Jr. <herzog@...>
 

Passed the Tech license exam.  Received my call sign today (KD9JVM).  I own a ThumbDV and have the BlueDV software installed on my laptop.  I have identified the corresponding com port for the ThumbDV (that is currently plugged into said laptop).

That all being said...is there a howto on what I need to do?  (register with d-star?  configuration for the software?  etc?)  I am completely clueless at this point!  :(

Re: Pre BETA version of BlueDV AMBE OTG

kyle@...
 
Edited

This adapter seems to do the trick for me:
https://www.amazon.com/USB-Type-HDMI-Adapter-ChromeBook/dp/B06Y443BQH/ref=sr_1_1?ie=UTF8&qid=1513110472&sr=8-1&keywords=piaek+fast
(note: ONLY the one that claims "fast charging" in the description) It does not actually "fast charge" but it does charge my Samsung S8 while powering an external hard disk - providing I connect a charger with enough current to spin that hard disk.
The only issue is they don't seem to make one for micro-USB.

I'm a little unclear on the design of OTG. When I connect a device to my Samsung, I get the following options:
- Transfer media files
- Transfer images (only use this if the above selection doesn't work)
- Connect a MIDI device
- Charge this phone
- Charge the connected device

So, the OS is trying to figure out what to do. However, those choices only seem to apply when no external power in the mix.
When external power is supplied (via the extra USB-C port on that adapter), it doesn't matter which option I choose. I can access the USB-connected device while power is supplied to BOTH the USB-connected device and the phone. This thing looks just like the Apple USB-C to Digital AV adapter but it does not act the same. This one actually does what I want - in my case, play videos over HDMI and/or access USB storage devices WHILE charging my phone.

I don't know how much current this external hard drive requires, but I'll bet it's more than a ThumbDV. I wish I had a ThumbDV to test with.
I've been holding off buying one in hopes that this specific application comes to fruition (i.e., connect ThumbDV to my phone and communicate over D-Star/DMR using only the microphone and speaker on my phone / without a digital radio).

Looks like it's time to jump in - if only it weren't so close to Christmas. I guess it'll be after the 1st of the year before I can buy a ThumbDV now.


Re: Pre BETA version of BlueDV AMBE OTG

 

Even when I use a wireless charger and then connect my ThumbDV, the android device stops charging.

Looks like OTG can only sent power to an end device like ThumbDV and can not receive power while OTG device is connected.

I have done several searches, and in general many OTG implementations cannot do charge and data transfer simultaneously.

However, if you are powering peripherals off a cable splitter, then the Android devices should run their normal battery life for specific programs.

I would love it if someone can show otherwise (and what devices they have found will do both).

Re: OTG charging issue

kyle@...
 

I posted this under another topic but it seemed relevant here as well...
The Apple USB-C to Digital AV adapter will NOT charge a Samsumg S8.

Just thinking out loud...I'll bet I can keep my Samsung phone charged wirelessly as long as the adapter cable can supply enough power for the ThumbDV.

Re: newbie trouble

lowbytes@...
 

Hello
I´m also new to this group and hope that i´m posting to the right thread.
Im running BlueDV on different setups and with different hardware
On my windows machine (Surface 3 Pro) im running an ambe3000 board as a dongle without any Problem
On this machine also my BT BlueDV Hardware (vie USB) running without problems
But i´m in Trouble to run BlueDV on Android or Linux - the only device running BlueDV without any Problems (BlueStack paired via BT) is my Samsung S8Plus
On all other devices (Nexus 7 - Samsung Galaxy s6Edge Plus HP Touchpad@android7 and Raspberry PI3) i can only connect to the BM Network ! Each time i try to connect
to DMR+ Network there is no connection to any DMR+ Server - the Setup the field for choosing any DMR+ Server is empty - If i start up BlueDV in DMR+ mode - i always getting an
Error ........... Trying to connect - Reconnecting - but never getting a connection to DMR+ - I wonder that there is no way to select a DMR+ Server like it is for Brandmeister .....
Any Suggestion how to get it up and running ? BTW the S8Plus is not rooted - all other android devices are rooted - may this causes my problem?????
Thanks for sharing your ideas

Pre BETA version of BlueDV AMBE OTG

 

Hi All,

If you have an OTG cable, a phone/tablet that supports OTG, ThumbDV and time to test... 
Please sent me the following in an email:

- The email address that is used in the play store
- Photo of the OTG cable 
- The type/brand of the OTG cable ( to build up a database of working cables )
- Type of phone/tablet ( to build up a database of working devices)
- Your call

My email: info@...

Will pick randomly 10 persons after 12 hours from now so every timezone can test.
Keep in mind that the OTG version is still very buggy because I am still working on it. 

Greets and thanks!

Re: WiFi vs. 3G/4G AMBEServer

 

Hi Chris,

OTG will be added soon. Then you can connect the ThumbDV directly to your phone.

Hi David,

Yes this is the 3G/4G on my end. The delays are quite long and the audio is slow and distorted. However, the app works great across wifi at my home, where I've run DSTAR and other nodes, even a full duplex Allstarlink repeater, for years.

What did you mean by the "OTG" version.

Hi Chris,

Yes this is related to the 3G/4G connection. Reflector and AMBEServer traffic is UDP so when a frame is dropped you will hear a gap. I am buffering a lot so I can deal with some jitter. The OTG version will give better quality because you only have reflector traffic left. Even when you miss some traffic, I am filling that up with white noise ( only DSTAR ).
