Calibration process hanging
|
HA3LN
Hi All,
I used to be a happy user of version vnaJ.3.1.11 for long time executing the jar directly. Most probably due to the updates of the java environment I got missing dependent library error msg at the start-up: http://ha3ln.hu/java.jpg I tried to update several version of different java versions with same result. I downloaded the newest (3.4.7) version of vnaJ assuming this must work with the latest java envs. However it starts-up but when I try to create new calibration for my minivna pro hangs for ever during the process. It starts to count the samples and sometimes I can perform the first of the 3 (open, short, load) but at the second run hangs each and every time. I cannot surely exclude the java env either but I followed the instructions from the manual. Has anyone came across with this symptom? Could anyone help how to overcome this step? Thanks in advance. 73! Csaba HA3LN / HG3N |

Hi all I have had some issues related to calibration of Mini Vna Pro BT2. It was not possible to calibrate it correctly. It used to happen after long time of not using Vna /I think/. Then I tried to reset instrument using the small red knob and it helped. Juro om2xa Dňa so 7. 8. 2021, 16:21 KA4INM radio <ka4inm@...> napísal(a): HA3LN wrote: |

...I haven't tried with BlueVNA as I use it with laptop which has more capabilities and easier to handle.

I'll give a try. Hanging I mean this: http://ha3ln.hu/hanging.jpg It sweeps the OPEN as it should and when I put the short to DUT gives this window and does not move forwards at all. 73! Csaba On 2021-08-07 14:32, KA4INM radio wrote:

Tried but unfortunately did not help to move forward the 2nd calibration step. :-\ 73! Csaba On 2021-08-07 16:47, Juraj Neupauer wrote:

I had a similar problem after a computer crash and trying to install the SW on a new PC. My VNA did run OK on the Android app though.
Somewhere on the road is says new VNA/Js are no longer compatible with the old firmware:
”This is due to a miniVNApro firmware bug for versions <2.6.
miniVNApro with firmware < 2.6 is only working with vna/J up to version 3.1.14 miniVNApro with firmware = 2.6 is working with all versions of vna/J
Firmware 2.6 is mandatory using the extender and/or vna/J > 3.1.14.
To use all version of vna/J > 3.1.14, you have to update the firmware of your miniVNApro to the newest firmware.”
That was my problem. After downloading an old VNA/J, problem gone.

Checked the device with the old laptop with old java version and works flawlessly. 73! Csaba On 2021-08-07 19:05, HA3LN wrote:

Hi All,
I have seen so many problems after Java updates I generally try to avoid doing them at all—unless I have a very specific reason to do otherwise and, I always create a system restore point just in case I have trouble. The truth is, we are all just un-paid beta testers for Java and Windows. If something bad happens, you can complain about it (assuming you know what they did) and it’ll probably get fixed in the next release.

Actually I cannot get the old version of java which might be suitable for the older version of vnaJ. 73! Csaba On 2021-08-07 21:48, Andi wrote:

This might be the problem then. I cannot use my old vnaJ 3.1.11 version due to the new java version. Where can I obtain the FW? Cannot find it on the vendor's page. Thanks and 73! Csaba On 2021-08-07 20:11, Roland Nyman via groups.io wrote:

I'm using a rather recent JAVA version I think. Probably downloaded it in May when trying to get the vna/j running on the new PC. It says version 1.8.0_291-b10. I have no idea of what it means. I haven't tried a FW upgrade. Looks a bit scary. Maybe you can find something on DL2SBA's home page or a MiniVNA forum https://groups.io/g/miniVNA.

There is a newer JAVA version available, but I haven't downloaded it. I'm using vna/j 3.1.13. 73, Roland SM0BRF -----Ursprungligt meddelande----- Från: miniVNA@groups.io <miniVNA@groups.io> För HA3LN Skickat: den 7 augusti 2021 23:28 Till: miniVNA@groups.io Ämne: Re: [miniVNA] Calibration process hanging ...thanks Roland.

It might sounds silly but even if I re-installed the old version of java the previous vnaJ 3.1.11 still gets this error: http://ha3ln.hu/java.jpg Tried everything I could but it's stuck. 73! Csaba On 2021-08-08 12:03, Roland Nyman via groups.io wrote:
