Thanks for the comments on the screen size.
I have spent last few months playing with Bluetooth and planning to add BT technology to the NanoVNA.
I was hoping that somebody will "update" the processor which would include BT or other wireless technology.
It seems most updates are to increase the frequency range, which is of no interest to me.
When I started on that I had real headache "working" with NanoVNA OS without having access to the hardware.
It will be non issue after I get my NanoVNA.
