Re: Is your RAW traces healthy? #stability #shielding
I don't have gcc at the moment, so I cannot implement patch for your compiler. You can try the following change: volatile uint32_t dfu_reset_to_bootloader_magic __attribute__ ((section (".noinit")));

Re: Is your RAW traces healthy? #stability #shielding
you can fix that bug for your compiler by placing variable dfu_reset_to_bootloader_magic into non initialized section to prevent it's initialization on startup.

Re: host software for nanovna, for linux users.
If something was written in a common base version, such as 2.7 for Python, which is probably pre-packaged in 90% of Linux OS's then I bet life would be much easier. - Andy -

Re: Is your RAW traces healthy? #stability #shielding
With my compiler it leads to "dfu mode won't work" bug. original board.c method uses hardcoded random ram address which may be randomly overwritten by stack filler.

Re: host software for nanovna, for linux users.
If you're not a noob to Linux, then why are you using Mint 17.x which is out of support? ???? I run nanovna-saver on Linux Mint 19.1 and it works quite well.? Installing Python 3.7 was no

Re: Is your RAW traces healthy? #stability #shielding
Revert back to original( ttrftech ) board.c and change callback in UI, problems( not to jump address ) gone

Cables
The included cables are not Rosenbergers but are there any good and low cost sets? Or are they more than the VNA itself? John I ain't designing a ecm GHz device, just sweeping antennas

Hello Dick, There are several firmware versions available: /g/nanovna-users/message/7477 has a snapshot of firmware in the wiki.

Re: Offtopic: nanoSA
Small post giving some background on the building and tuning of the 2GHz cavity filter. I was able to use my nanoVNA to check the tuning of this filter as described in another post

Re: retrofit a bigger screen
Actually, his Android app still calls home to mama Google for statistics.?? If you have your Android device's WiFi enabled and connected, the NanoVNA app starts right up. However, I run a firewall

Re: NanoVNA-Saver and NanioVNA-Q
Hi? Rune and QRP RX Yes indeed, running a calibration on my NanoVNA-H itself first, solved my prtoblem. The calibration with 60 segments and 10/5 Averaging over 10K to 900M is still running :-D:-D Oh

Re: retrofit a bigger screen
Using cho45's NanoVNA apk avoids Internet dependency: https://play.google.com/store/apps/details?id=net.lowreal.nanovnawebapp .. and Amazon Fire tablet is currently < US$30

Re: NanoVNA-Saver and NanioVNA-Q
Thanks Rune and QRP for responding that quickly, I did nothing more? than the flashing and trying to calibrate in NanoVNA-Saver, I wil run a calibration on NanoVNA itself and see if it solved it !

Re: retrofit a bigger screen
Another way to do this would be to package it up with an Android tablet and use NanoVNA WebApp as the user interface (remove or hide the built-in LCD). I'd like to try this but the android app won't

Re: NanoVNA-Saver and NanioVNA-Q
even if you cleaned your connector with alcohol, you're needs to perform calibration after that

Re: NanoVNA-Saver and NanioVNA-Q
any change, firmware or hardware requires a new calibration.

Re: NanoVNA-Saver and NanioVNA-Q
Hi Jos, I haven't done anything in particular relating to the NanoVNA-Q firmware, so any changes, assuming you are using the same version of NanoVNA-Saver, is in the firmware. :-) The individual

Re: NanoVNA-Saver and NanioVNA-Q
if firmware detects incompatible calibration it reset calibration and settings. You're needs to perform calibration after firmware update.

Re: NanoVNA-Saver and NanioVNA-Q
Hi Rune After Flashing NanoVNA-Q-0.4.4 I found that the calibration in Nan0VNA-Saver has changed. I am used to set the sweep settings in the NanoVNA-Saver to a high number of segments and averaging
