VH Win10 client does not work since I reimaged my RPi4.

Submitted by MiguelE on #1

Hello there:

As the subject line says, VH Win10 client does not work since I reimaged my RPi4. I went from Rasberry Pi OS 32-bit and vhusbdarm server to Manjaro 64-bit with vhusbdarm64a72.

I saw a message on the client side that said that I have to purchase a license but I already purchased a license.

Please advise how to correct this.

Thank you,

Miguel

OK so just put the license key in again. Did you try that?

I can not put the license key in the license key tab of the client because it says it is not connected to any server. I see the client trying to connect as it is in auto mode but it fails to connect.

What do the system messages say in the client by right clicking USB Hubs->System Messages

"I can not put the license key in the license key tab of the client because it says it is not connected to any server. "

Thank you for your help.

I got it all to connect. The server was not starting automatically after boot. I found an old post of you troubleshooting a similar problem. There, you advised the user to I think move the server to another location (I believe that was the command but I do not know Linux commands) then, to create a server.service file. That fixed the server not starting at boot up issue.

I now have an image download issue with the astrophotography software I use. They require taking and analyzing images very fast but for some reason, they are not able to. They freeze and say the image cant be read. My wifi at the RPi4 is consistently faster than 300Mbps so speed I do not think is the problem

Any advice on this?

I think its very likely the wifi connection actually. Just for a test, plug an Ethernet cable into the pi and use that for the network instead of WiFi. Does that make a difference?

I have the scope and cameras setup outside now and I cannot run etherenet cable there. I will test that.

Please forgive my ignorance about the topic and lets assume is wifi connectivity. What could fix the problem: more Mbips at the RPi location? Or is it a Pi hardware limitation?

Thank you

Yes WiFi has high and variable latency compared with Ethernet because WiFi needs to listen first if there is any one else broadcasting and also the signal sometimes gets attenuated. To make matters worse, the pi4 wifi chip has 1T1R radio (one transmit,one receive) and a small ceramic antenna.Using a 3T3R dongle would help a lot https://edimax.freshdesk.com/support/solutions/articles/14000063861-how…

Anyway to see the latency statistics in the virtualhere client, right click USB Hubs->About->Statistics and watch the latency graph when you use your camera via wifi (and via Ethernet) it should be stable and about 10ms or less

Michael thank you for your help. I will check the dongle solution. I also have a spare router I am going to test using it as a wireless bridge and connect the pi with gigabit ethernet.

Thank you again
