URGENT - Victor LS bluetooth taken on a life of its own...?!

Hi,

My Base (T2 + HPT435BT) and Rover (T2 + Victor LS) was working great ... until the Victor LS started rejecting / or not finding the base T2 spontaneously (GNSS not found). What's more, is that even if you reset NVRAM on the base T2 (as per previous advice to another user) as well a reset (well, delete all data) of the Victor LS the problem persists. All the Victor LS software seems to be up-to-date. If you try turning off the bluetooth on the Victor LS, it turns itself back on spontaneously, and in fact just turns off and on all by itself.

One peculiarity is that if you disconnect the radio, the Victor LS sometimes finds the T2 base, but looses the connection as soon as you turn the radio BT on. So I unpaired and repaired the radio and T2 Base (in fact I did this twice to make sure I was doing it correctly) - but it doesn't help.

One thing that I don't know if it's of any significance is that the T2 Base when it shows up in Windows Bluetooth Devices has a number in brackets after it 'T0185 (,35,)' - whereas the T2 Rover doesn't 'T01995 (,,)'. I am not sure what that number means... (I am assuming it's to do with the Radio Pairing).

Failing that, is this a hardware issue with the Victor LS? Could you advise? We really need this equipment to work - or else we are in trouble.

Thanks,

Andrew W

Suggestion:
Carefully clean the screen, then recalibrate it.
A bit of dirt, or hair on the screen, or around the edge may be contributing.

Hi - screen wasn't totally clean, but not bad either. Cleaned and recalibrated. No difference. Still doing its thing bluetooth cycling thing. When the bluetooth turns itself on, it recognises T2-base in Bluetooth screen (sometimes multiple records) but then it is not connecting when setting up base-rover - (Unable to connect to external GNSS receiver) message. It searches but 'can't find' the T2 in the Base-Rover Set-up screen.

I note this morning, however, that when the T2 Base is switched off, the Victor LS Blutetooth seems to settle down and behave. When T2 base is turned on, the bluetooth on the Victor looses the plot and starts cycling 'Off and on'.

Thanks for the suggestion tho!

For the Bluetooth to work properly, the Victor-LS will need to be rebooted anytime the rover's Bluetooth connection is disconnected. Also do you have "Autoconnect to Base" (Bluetooth icon > Configuration) turned on? You might try turning it off if you do.

The 'auto-connect to base' is not selected. I have rebooted the Victor many times, and this does not help. There is something up with the bluetooth, or the software driving it. The only thing I can think of doing is reinstalling J-Field? There is something definitely not right. I'm pretty good with computers and hardware... so I am a little bit at a loss...

You can try setting the unit back to its factory state with System > Restore > Delete All Data On Reboot. This will erase all the settings and project data on the unit so make sure to copy off all the project data you need before doing this. If you want to reinstall J-Field and WinCE OS this is done from System > Software Updates > Configuration button >Advanced Settings >App Settings and the set J-Field and WinCE OS to Force.

Hi Matt, I had earlier cleared the data and rebooted the Victor LS, as per your suggestion, without any impact. So I went straight to try both J-Field & WinCE OS to Force. No change in the situation. I then reinstalled the firmware of both T2s and re-tried with the T2-Base. No change. I then unpaired and repaired the Base, no change. I then swapped the T2s around so that the Rover became Base and the Base Rover (by unpairing and repairing, all the time clearing the bluetooth favourites as well clearing the Headset History, no change. Finally, before throwing the towel in for the evening, I tried clearing the Victor LS data again, and this time it worked. I have no idea why. I'll test the system properly tomorrow - but it seems to be working now. Thanks for the support.

Hi Matt, alas an ongoing post-script.

Unfortunately it seems that in order to be able to get the Victor LS to recognize the BaseT2-UHF Modem pair, one has to Delete all Data and reboot the Victor LS, and then start afresh - each time. As soon as one shuts down the Victor LS, having stopped the base first, and then switched off the T2 Base, Radio and T2 Rover (after the Victor LS has turned off), it's not possible to get the system working again without a data wipe and reboot on the VIctor LS. If you don't, then the 'Unable to connect to external GNSS receiver' when connecting to base happens.

We can operate this way, but it's far from ideal... can you think what might be causing this?

Cheers,
Andrew W

Hello, dear Colleagues.
So, we checked problem with Victor-LS with Base, Rover and External radio configuration. With a certain sequence of settings, a situation arises, after which it is impossible to connect to the Base receiver. There are no problems when you connecting to Base, use paring/unparing with External Radio through the Bluetooth and starting Base. After starting the Base it is possible to connect with Rover also through the bluetooth and do the survyeing. The problem appears if Victor-LS simultaneously connected with Base and Rover. If in that status try to do pair/unpair with external radio, both bluetooth ports on Base sticked in Echo mode and you couldn't to connect to the Base receiver. If check Bluetooth status on Victor-LS it will show bluetooth connect status for two receivers (base and rover) with the same serial number. This problem dissapeared after Clear NVRAM on Base and restarting Victor-LS.

Hi Mikhail,
Thanks for your investigation. What you say makes sense - about the BT being stuck in echo mode. Unfortunately I have traveled, and had to leave the equipment with one of the survey teams I am working with in Uganda, with instructions on how to clear the Victor LS data and to re-enter the Base-Rover settings each time they want to use the equipment. I'll ask them to clear the NVRAM and see if they can get things to behave normally as per your suggestion. I have reset the NVRAM on the T2 Base before, but perhaps not in the right sequence to include turning off the Victor LS. Let's see what happens - I'll be back on this thread with an update as soon as I am able.

In the meantime, thanks very much for your diligent support in trying to reproduce the problem!

Regards,
Andrew W

Hi Mikhail,

Apologies for the delay in getting back. The problem seems now to have gone away (thankfully).

Just an fyi that at some point the something needs to be figured out (at least it would seem so) with a different BT bug - where the Victor LS can't receive sat data from the T2 rover, even though it is seemingly connected, and it may also connect / disconnect intermittently. This is solved by rebooting the Victor LS (on the advice of Matt), and re-establishing the BT connection, but one often (it seems) has to be in BT range of the base, to also use BT to re-establish the UHF radio connection with the base radio, before heading off to work.

It would be great if a firmware update ironed this little and somewhat inconvenient re-occurring wrinkle out.

But thanks again for the support.

Regards, Andrew W
