Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Connect nanoVNA to HC-06

Anne Ranch 2022/06/11 09:12

I am sure this has been asked before , however, I am after to where I physically connect HC-06 to nanoVNA ?

1. Connect to UART ?
2. if so WHERE ?

I understand it depends on actual hardware...
I also understand that it is not that easy to identify such hardware
versions / clones etc.

If I can get answer to item 1 I could then post the picture of my device...
if it helps.

At this time I am not concerned / asking about software , but I have the device stripped of back plate so
I figure to ask about how to physically connect to  Bluetooth module.

Dragan, appreciate the post, however, my current state of
"adding Bluetooth module HC-06/05 " is

unless the PCB has CONNECTION to UART

- some PCB "versions"
have such connection  labeled  "P3 " -
it would be major challenge to
solder required  wires to some convenient point on PCB ...
( No thanks...)

Anybody willing to trade "P3 " connection missing version with "P3 " connection
"wired " ?

No, you do not need "P3" if you are NOT using Bluetooth modules, however,
the *sure way to KNOW* your board HAS "P3" - is to *REMOVE the back* cover
of the device and LOOK !

Post the images of your board.

What and why post this ?

1. The post was about ADDING - "using Bluetooth "....
2. How do you think I KNOW I do not have "P3" on my device ?
3. Posting image for whose benefits?

(Your ) reply is utterly illogical time waster , and it this offends  (you) , or anybody  else,
I got nothing else to add.

Hi Vaclav,

You need to be very succinct and timely in your questions and responses.

If, as you state, you know that you have a earlier revision board which does not have P3, then you need to obtain a newer board.

(I would suspect that no one would be willing to trade their NanoVNA for your earlier version, so that would suggest that your BT connection desire can only be meet by purchasing another, newer, unit.)

Should you obtain a board with the P3 connections and still desire to add BT, then the link provided in this thread gives all the information needed to do so.

Take care,

I definitely  "do not need " to be told how to communicate. It is my choice.
I have posted about "adding Bluetooth"  TECHNICALLY , and that has been discussed.
*And I do appreciate all group contributions.*
Any none technical suggestion are unnecessary - I am perfectly capable  to make
decisions on my own.

*consider this closed , no more "discussion"  nor (purchase) suggestions.*
