DMR, Thanks for the cygwin notes!

INSTALL: ChibiStudio, java, MINGW, Cygwin in disc C.

Prescribe:
Prescribe "PATH" in ChibiStudio (Eclipse) (C:\gcc\bin)
prescribe "toolchain" in ChibiStudio (Eclipse). (Cygwin)

In Windows, the control panel, the system, in addition, environment variables (bottom and top).

Prescribe "PATH" C:\Documents and Settings\All Users\Application Data\Oracle\Java\javapath;C:\gcc\bin
Prescribe "PATH" C:\gcc\bin

Better to apply PATH, by downloading Lpcxpresso $ PATH=$PATH:/Applications/lpcxpresso_7.8.0_426/lpcxpresso/tools/bin

To the project file, copy all the contents from the folder ChibiOS.
Download from here

When importing a project, select Cygwin compiler.

In the file (rules.mk) below, delete the following lines

It's beginning to sound as if shipments should be accompanied by a

sentry with an Uzi!

More seriously, consider the ubiquitous plastic storage "tub" for

shipping electronics items. It's inexpensive, it is light and, unlike
cardboard, it remains useful for domestic purposes at the far end. There
is a range of sizes from kitchen shelf utility suitable for nanoVNA
equipment all the way up to huge.

This occasional shipper drills eight or ten holes through the lid

and tub lip and then secures the lid by cinching up Tye-Wraps through
the holes. The cut end of a Tye-Wrap can have a sharp point; take a
moment to pass a lighter fame along the cut ends to "blind" them.

For heavier equipment, there is the great advantage of "handles".

The shipper's personnel have an obvious and easy way to move the item.
Inadvertent and perhaps even "spite work" dropping are less likely. Even
a heavy high frequency radio transceiver can travel safely suitably
packed into a "tub". In addition to all around packing, the precaution
is taken in such a case of placing layers of corrugated cardboard in the
bottom to absorb dropping shocks by being crushed.

Should a dispute arise, note that abuse of the container is shown

vividly by white witness marks remaining where the plastic had been
violently flexed.

here's what my prototype looks like. clamshell is suspended in the middle of the box, and restricted from moving nearer to the edges when/if the stuffing/padding shifts. more stuffing/padding to be added on top before closing the carton.

You'll probably be better able to build in a Linux VM running on Win7.
Have you tried contacting the two forum members who supposedly had successful builds?
Their posts are around the end of July-beginning of Aug.
There is also another member trying to build - his posts are from last week.

Also - do a search on Github for NanoVNA-F and you will find that someone used FreeRTOS instead of Chibios

You might want to go that route.

Good luck!

I just received mine from Guangyi0016 on AliExpress.
This particular unit came with a battery (as ordered), two cables, and 3 cal terminations.? It appears to have complete shielding around the mixers and connectors (as viewed between the panels, I did not disassemble it to inspect).? A quick test shows it has the four trace firmware installed (didn't verify the mhz range). Looks like I'll have to remove the front plate to get the plastic off of the LCD.? This is the black faced Nano, with no logo, just 'NanoVNA' in the lower right hand corner.? It arrived with some charge in the battery.
The unit was packaged in a plastic box with snap lid, wrapped in a good sized wad of bubble wrap, and shipped in a box measuring 7"x3.75"x4.5".? The box was not dented at all in shipment.?? The seller shipped in 5 days after I placed the order, and it arrived about a week later.? Very good experience with this seller.

Hi all,

I've been trying to build the FW for this as I would like to make some changes but it fails to build. I've found that it needs ChibiStudio but I can't get that to build or run. There is a preview version but it seems that this only runs on 32-bit windows.

Trying to build the FW, produces many errors most related to missing include files, both standard inlcude files and local include files (e.g. ch.h and hal.h, these don't exist in any of the source downloads I've tried although there are local includes for chconf.h and halconf.h, just not sure if this is what I should use).

After a bit of research looking at the make files, I discovered the need for ChibiStudio. Looking through the source for this, it contains the missing standard include files but as I said, this won't run on a 64 bit Windows OS (Win7 in my case).

Would be grateful for any info as to how I can build the FW.

Thanks

I ordered an nanoVNA at Aliexpress store 'meterk Official Store' and they did not ship within time, so cancled.
Now I have another pending order at Aliexpress 'BIGHelp Store' and there are only two of 8 days left, until the
order will be automaticaly cancled, because it has not been shiped.

Is there a shortage on the item or what is the reason behind offers with no goods in stock?

Any stores recommended?

A package like that could be nice, but at least a 2 port contraption.

I've attached a photo of the Sk4000. It is a self-contained test device with an N at one end.
Per your request for an all-in-one device, it's still doable in the same manner as the SK4000.

With the availability of 3D printers now, it is easy to create a housing to accomplish what you want.
The advantage of having an Android or iOS device as the brains, means you get to use its computing capabilities for other RF/Tech/Design applications.

I was considering that. Looking at some from the adafruit site. Also full size connectors. I wanted to take a look at the code first as there is probably some display adjustments to be made.

Hello Hugen,

The use of the Zadig drivers does indeed solve the problem of operating the WebUSB app in Chrome on a W10 machine. I downloaded the drivers and got it to work last night. However, getting this functionality appears to be at the cost of the NanoVNASharp v1.03 application. With the change in drivers the 1.03 app no longer finds the NanoVNA. To solve this I have had to rollback the driver change. I think that for now I will leave my W10 laptop set up to run the v1.03 app and use my iMac for the WebUSB app to run the TDR function when needed.

Might I respectfully request that perhaps what is needed in a new version of NanoVNASharp (1.04 perhaps) that contains a TDR function and a repair of the previously noted problem about the sequence of Calibration events.

Thank you for all that you have done to bring this amazing unit to market.

I would like it to be a self contained instrument, not one that depends on a computer or phone for the screen. To be able to interface a computer or tablet to it would be nice, but I don't want to have a bunch of things hung together just for the VNA itself. For me, this is a tool to be used in the field, not necessarily a bench only instrument.

Burt, K6OQK

Having a small pocket size VNA is a neat thing, but speaking for myself, I'd much rather have a tablet size instrument, say 7 to 10" preferably in a metal box such as the Hammond 1590 series. Thicker wouldn't bother me, and something with Type-N connectors. Hopefully that will come about in the near future. Of course it would cost more, but it would be well worth it to me.

Again, that's my personal wish.

I use a Bird SiteHawk Sk4000 antenna analyzer at work and had to repair it once.

When I opened it up, I discovered that Bird engineers used a slightly modified Samsung 6" cellphone for the display and processor brains of the unit.
All of the RF guts were inside a solid shielded module.
The RF module was connected to the Samsung through its USB (OTG) port.

So - something similar could be designed to take advantage of all the Android (and possibly iOS) cellphones and tablets with multi-core processors and HD displays.

As mentioned earlier in the forum, maybe a headless version of the nanoVNA could be designed that goes up to 2.4GHz or higher that has a USB interface only.

For anyone interested, the SK4000 apk can be downloaded from the BirdRF website to play with.

You just need to make sure that when the truck wheel finally hits, there is not just weak stuffing, but something really strong to keep it from crushing the thing in the middle. Probably adding a few layers of the cut-out cardboard would do it. (A sturdy outside carton would also help.)
