Hi,

I've had a NanoVNA for a few months now and I'm very pleased with it. It does everything I ask of it, having said that my main interest at present is in HF and VHF frequencies. Initially, I looked forward to updating the firmware as and when improvements were made, but viewing the sad litany of people having trouble with updates I'm put off performing any updates for the time being.

As I say I'm perfectly happy with it at present, NanoVNA-Saver works fine and is a great asset so don't have any great desire to update. it just seems a pity that it seems to cause so many people problems.

As is said, if it aint broke, dont fix it.

That's not the way to think about it, Charlie!
If Michael wants to use some of the newer PC applications, he will need to upgrade the firmware or things may not work properly.
Yes, he can stay with the older apps, but OneofEleven's Nano-App.exe needs at least 1.0 or greater firmware.
Michael - it's actually very easy to flash - just follow the guides.? Grab the newbie guide.

You cannot 'brick' the device - I proved this to another user when I pulled the USB cable in the middle of an update. All I did was to short the BOOT-0 pins to place the unit into DFU mode again and re-flashed the device. The only caveat is to make sure you use H FW on an H device, H4 FW on an H4 device and F FM on an F device.
You have an H device so download the 1.0.45 zip file from the forum files area, unzip and flash the H version to your device.
I compile and flash my own changes - once you've dome it a couple of times - you got it!

Larry,

Have you compared the DisLord and Hugen firmware version 1.0.45 on a -H4? Apparently the Hugen version uses larger font sizes but I don't know if that is the case on the -H4.

I am currently using the DisLord version on a -H4 and it works great but if the fonts are easier to read with these old eyes i will upgrade.

Guys,

I have done firmware updates for many different devices over the year since flash chips became mainstream. Once you get your ducks in a row the Nana/Tiny updates are among the easiest ever. There really isn't any reason NOT to do it and very good reasons TO do it.

Hi Roger,
I'll have a look at the source on Fri.
?I finally got DiSlord's H4 1.0.48 code to compile today.

I'll see how the fonts look. I .did. load Hugen's code on my 2.8" unit last week but didn't like it so I loaded DiSlord's 1.0.48 on it.?

Roger - the larger font is only on the H. The H4's font in unchanged.
