Re: Default com baudrate settings? NanoVNA-H

 

Roger,
My NanoVNA-H has v.0.2.3-2-g8ac9166, (not sure of the "g"), dated Build Oct 10, 2019. Does that fall into what you call "old FW"?

If so, Don't know what is involved in gaining "the required the binary protocol that DiSlord implemented in the NanoVNA-H firmware a couple of years ago.

Thank you for your insight and assistance,
Ray, w4byg

Having some trouble getting my NanoVNA-H to talk to NanoVNA-App. The app
says it's connected via com 3, but it's not controlling the nano, or
exchanging any data to and from it. I've tried several baud rates, but
no dice.
The baud rate does dot matter on a USB "COM port". I suspect the reason NanoVNA app is not working on your -H is because you are using old firmware. The old firmware used text transfers for data exchange to the PC and if you connect to NanoVNA app nothing happens which is what you are seeing. NanoVNA app requires the binary protocol that DiSlord implemented in the NanoVNA firmware a couple of years ago.
