Two (joined) cable calibrate and DFU firmware upgrade
1) frequently connecting and disconnecting directly to nanoVNA's rather fragile connectors accelerates wear and reduces operational lifetime 2) ANY changes between calibration configuration and subseq

Order of calibrating
At least using 2019 nanoVNA firmware, order DOES matter: the device is making the "next" measurement until that expected button is pressed. If an unexpected button is pressed, current device data is f

Bluetooth HC5 and nanoVNA-H
Many new smartphones support only BLE (Bluetooth Low Energy or Bluetooth 4.0), which wants e.g. an HM-10 module.

Can the NanoVNA be used on 75 ohm cables/ antennas --- Part 2 #75 ohm measurements
I made naive calculation for software correction of (nanoVNA) bridges at other than balance: https://oristopo.github.io/nVhelp/html/bridge.htm Bottom line: math is doable, but reduced sensitivity slop

Thanks for feedback; I was also lost there before; CORRECTION option was added by some firmware "update". https://books.google.com/books?id=mGkIAQAAIAAJ&pg=PA190&lpg=PA190&dq=Friedrich+Schiller+%22bli
