S-A-A-2 N with 4-inch screen


John Galbreath 2021/05/15 12:01

My new Aursinc Nano VNA  SAA2N V2.2 works well with NanoSaver & NanoQtT, but not with OneofEleven.  My firmware version is 2020-05-01.  This info is from Menu Map, and not shown in Config data display.

My VNA has a menu map path (Config - DFU ) for firmware update, whereas the instructions on NanoRFE website directs user to hold left job button during power-up.

0.  There are several NanoVNA gadgets in circulation.  My gadget has N connectors.  Am I looking at the wrong website ?

1.  Can I use my VNA with One of Eleven program if I update the firmware ?

2.  Is it possible to cause irreversable problems in attempting to update firmware ?

Hello John!
Please download FW from Website
https://nanorfe.com
Your verdion is very old.

https://nanorfe.com/downloads/20201013/nanovna-v2-20201013-v2_74.bin
By nanorfe.com you can find manual for this version.

Or you can download:

https://nanorfe.com/downloads/20201124-experimental/nanovna-v2-20201124-experimental-v2_74.bin
It is experimental, but good. Manual is the same as for version 20201013.

You can use NanoVNA-APP 1.1.206 after fw update with NanoVNA-QT.

Best regards

Hello John!
Please see item # 1371 for the latest firmware for all V2 versions from user DiSlord. Please pay attention to the information about FPU in the device.

Hello Siegfried!

It is unknown if John has a device with an FPU. As a precaution, he first
needs the FW WITHOUT FPU support. If it is certain that CONFIG ---> VERSION
has the entry - FPU = yes, then it can load the FW you have proposed.



Best regards

hello vlad

oh .. i was guessing his device has fpu (never seen an saa2n without)

but you are right ... if his device does not have fpu he needs the one
you added
