A quick check on Amazon shows a simple USB female-to-female connector (set of two, actually) costs about $6. One of those and the existing cable that comes with the NanoVNA gets you ¡°on the air¡± (assuming you have a USB memory stick, which they seem to be handing out in cereal boxes these days ?).

Won't work - the Nano is a USB CLIENT.

You need to have a USB HOST port in order to plug in a memory stick. This has been discussed before in the forum. On Wednesday, December 8, 2021, 09:29:52 p.m. EST, Robb Cole N2VJO <robbnterri@...> wrote:

Greetings, Thank you for that information. But, I am not clear as to how to initiate an connection to,?and or the ability to exchange data to and from the SD Card which is installed into the NanoVna_H4?which I have. I did not notice any change of the device screen indicating a connection was now possible.?Also, I didn't notice any fields located in NanoVNA-saver application on my windows 10 PC. Must I install,?or re-install device firmware in order to affect the change that I have made by accessing the card slot.?Thank You

Any NanoVNA can control from CPU
Software like NanoVna Saver or NanoVNA-App open com port connection and send commands You or any programmer can update exist / write new software for SD card access Just use this commands At this moment this software not exist, but I hope there is an author who implements this option |

So there's lots of functions available by sending serial commands and getting responses back (as DiSLord illustrated) that aren't available from the touch screen. NanoVNA-Saver probably hasn't been updated to incorporate this new functionality. |

You need to have the last formally released version of DiSlord's firmware installed in your H or H4 for the 3 SD card commands to work. That should be 1.0.69 You can find in in an zip'ed file at /g/nanovna-users/files/Dislord's%20Nanovna%20-H%20Firmware Install the firmware, connect your Nano to your PC/Mac/*nix box and talk to it using a terminal emulator application. Read my Console Commands document also in the files section to see what commands you can run remotely from the terminal window. (it hasn't been updated in 2 years but it has most of the info you'll need. Also - please read the Beginners userguide, also in the files section and look through the forum Wiki for info.

Thank you for the speedy responses. I will read the guide as you suggest.?Of course, using a terminal emulator over the attached com port makes sense.?Admittedly, I haven't had occasion to use that method of conversing with attached?hardware in quite a while. Thank you for an outstanding and very informative group.

Don, Thanks! Actually, I have been using the H4 without any issues. It was only just?recently on the NanoVna Group that I learned the slot existed in the first place. At?some point I am sure it will come in handy.

Hello DiSlord;
Thanks for catching the essence of this thread so quickly. :-) I was suspect that you might be ahead of us on this, and it is awesome that it is already supported. I have the original edy555 platform, but with your incremental updates, it continues to play like a new NanoVNA-H. Even after bricking it a couple of times and physically abusing, breaking, and restoring it a couple of times as well, it just keeps getting better¡ and made new again. I ordered an H4 from R & L here in the US yesterday; not because I ¡°needed¡± to, but rather out of fear that if what I have breaks again, I may be without one for awhile. The bigger reason is that my aging eyes will benefit from the bigger screen, and the new added features keep inspiring me to use it even more. I applaud the incredible job at refining the performance and utility that you¡¯ve been doing, while enhancing and maintaining compatibility with legacy hardware. I was surprised to find that coverage now starts at 800 Hz, and also astounded at its performance in the audio region. It has become the new ¡°multimeter¡± for hams and analog professionals alike. What an incredible development team! Tonight I must order an SD card connector for the H4 that is on its way to me. If I understand your detailed response to this thread adequately; Putty should be a sufficient tool for porting and managing SD card data from a PC via the NanoVNA¡¯s USB interface. Is my understanding correct on this? -- 73 Gary, N3GO |

H4 already has the SD card connector on the PCB so no need for a new one.

First of all, thank you DiSLord for the responses, and I echo the many other comments in this forum about the most excellent support you continue to provide!
I opened the case on my H4 VNA and found the silk screen outline for the card slot, but in my case the connector is not populated. The good news is I have sufficient skills to solder one in. The bad news is I don¡¯t know what part to order.. Gary, if you have a link, please post it? -- Regards, Robb N2VJO |

This has been discussed in the forum messages a number of times - search for sdcard socket or sdcard slot
