Ambe server two DVstick in one raspberrypi? #ambeserver

Hi All,

Using a compass image and having a two thumb dv stick connected to one raspberrypi does it work as two ambe server? changing the port of each ambe configuration?
let say ttyUSB0 is port 2460 and ttyUSB1 is port 2461?

is there anyone have this setup? if yes how did you do it?

Regards,
Andrew

HI Andrew,

Yes, it works, with two DVStick30, with port 2460 ttyUSB0 and port 2461 ttyUSB1. We tested them, okay.

Hi Nomis,

I was able to test the two dvstick connected to a raspberrypi.
1. ttyUSB0 config file was set to 2460 service was start successfully.
2. ttyUSB1 config file was set to 2461 service was start successfully.

here are my observation.
if user one using USB0 and user two using USB1 and they are connected  at the same time.
when both are using DMR mode one is for example at TG 91 and the other one is on TG 515
both user will hear two talkgroups what ever comes first . which is not supposed to be.

Thanks and 73!

HI Andrew,

I am sure we tested this situation on the compass. Currently I only have one DVStick30 on compass, but two DVStick30 on AMBEserver (git). Rick and I tested today and no interference, I was on TG31689 (2461 port ttyUSB1) and Rick is on TG5159 (2460 port ttyUSB0) with no problem.

AMBEserver is a rather trivial program, it is not strongly dependent on the underlying OS (Unix/Linux distributions) and you can run multiple instances simultaneously.  Just select a UDP port for the network side and a serial port for ThumbDV™ (or equivalent device).

Hi John,

Thanks for your inputs. im using a compass image.... if i will create another instance on the same platform what are the folders should i copy or how would i do that?

Thanks and 73!

I was not able to successfully run two ThumbDV sticks on a Raspberry Pi 4B using the 2x USB2 ports. However, this setup worked fine on a rPi 3B Plus. Basically, neither stick would work while another was plugged in. For both, I used Raspbian Buster.

I've had other odd USB problems with the rPi4 as well.

Hi Patrick ,

yes im using raspberrypi3 B , did you create the other instance? i  know where to change ports but the suggestion to create new instance.... i haven't tried it because i dont know how to do it.
i have no idea what are the folders need to be copied for me to create instance im using a compass image.

Yes, I just made another copy of the AMBEserver.ttyUSB0 service, called it AMBEserver.ttyUSB1.service, changed the appropriate command line in that file, enabled the service and started both.

I did this already. See my 1st post on this thread i observe that it will receive both tgs on the each usb 1 and usb2 if they are both on dmr mode.

I have not seen that behavior when running multiple AMBEservers on the same system. Did you change the UDP port in your client to 2461?

That's not logical.  AMBEserver listens to one serial device and one UDP port transferring packets between clients and the AMBE-3000 chip.  Any talk groups, reflectors, etc. and the connection to those services are controlled by the client application.
