All antennas UNUSABLE after flashing the newest version

szymonunion · 2019-06-10 21:31:07

Hi!

I flashed after 2-3 months RDV4 (from repo) and I still have the same issues with antennas. Last time I had the same, but now I have no solution for this and I am asking for help.

Please find out attached info:

I tried already to flash all and also separately and there is still the same issue.

Thanks for help!

Was it working prior to the firmware update ? What was the issue/solution last time ?
Double check the antenna attachments (remove the antenna and re-attach end ensure a good connection).

Hi!

it was working fine 3mths ago, but I remember I noticed the same issues before it was working fine. Remove antennas? I do not have some extra external antennas only normal hardware as being sold.

What else I can check if flashing was OK ?

mwalker · 2019-06-11 08:06:27

You said it was the RD4 ?
If so, slide the cover off and you will see the antennas are connected to the main unit via a row of screws. (My RD4 came with with the driver to suit). So if you undo all of those (or at least ensure they are not loose). Next check the 4 screws that hold the LF antenna to the HF antenna.

If you think its firmware, then re-flash with the last working firmware. If that works then try the new firmware again. If that fails again, then revert to the working firmware and report back.

I tried 20190101 firmware, but it is still the same issue as the newest firmware. I will check it at home with a driver and check and after write here a status.

szymonunion · 2019-06-11 20:14:45

Screws are fine and I just checked if they are all fitting well.
Firmware is:

[ CLIENT ]

I do not know what to do now - I can't remember what version was working OK. I remember I had before such a problem, but I can't to find cliues now.

EDIT: it is not client version - I checked RRG build and the same. I found BTW that the last working build was about Dec,10 2018.

This is now past my level of knowledge so I will leave for someone else to respond.

make sure you always use the same client and arm versions compiled from the same codebase version. never mix versions. that can cause this type of problem

Thx, but I know about it and I am not mixing.
Problem is that I always have UNUSABLE antennas whereever and whenever I am testing. In December it was working few times, but when I was running 'hw tune' few times in a row I got 80% answers that 'UNUSABLE'.

Where did you buy the device? Just RMA it, you could have gotten a bad device. I remember your issue in december(?) As mentioned last time, I have gotten bad antenna values when I switched antennas, and I only needed to unscrew/screw it back and all was fine. Your device seem to broken since you still have this issue

Hi Iceman!

Yes, it is true. I will have to. I will just try to unscrew/screw and if it will be not working I will start RMA. I should do it before.
I will let know after.
EDIT: after unscrew/screw the same effect. I sent few hours ago request to Lab401 to start RMA procedure.

Hi Iceman!

Lab401 sent me a new device and it is working like a charm!

Great!

I suggest you add the prefix "solved" to the subject line
