Nano 33 BLE Analog help

Hello everyone,

I am new to this forum but not to Arduino.
I am working on a bench set up to read DC voltages and current and send wirelessly thru an Arduino 33 BLE wirelessly to a PC 160 ft plus away from where the nano is enclosed.The nano has to be powered by Vin and not thru USB.is it doable or am I dreaming here? I got the RGB led code to work but i still had to have USB cable connected to PC and I used LightBlue app on my phone

The voltage i am measuring is around 16 VDC and a current ranging from 0.2 A to 5 Amps .
I will share more info if anyone will be willing to help me.

I have the bench part working for several part of this project but I don't know how to send the data to PC thru Nano 33 BLE

I have two nano 33 ble
0-25 v voltage sensors
current sensors
0.1 ohms Shunt Resistors

Thank you in advance if anyone responds to my post

The power from USB or Vin should not be an issue, but In my experience a range of 160ft with BLE is not realistic.

What range are you seeing with your Nano33 and LightBlue on a phone?

Are you saying that the Nano33 BLE needs to be powered by usb (and not from Vin) for it to communicate with LightBlue on the phone?

Hi cattle, I tried it in parking lot, line of sight, i got 166 feet

Yes Cattle, thanks

The goal cattledog is to have 2 nano 33 BLE if i had two acting as central and peripheral for this project. On the peripheral one, it has to be connected by a rechargeable battery pack( 16 VDC) .
the analog to voltage reading , GPS data , SD card ( dont need that data transmitted) and all hardware will be connected to that board.

The Central board who is waiting to read the data from peripheral can be connected to a PC 160 ft plus away .I looked into HC05 modules, but it does not seems to like the bluetooth on the nano 33 BLE and the range may not be more than 10 meters.

Thank you for responding Cattledog. This is a hot project and not for fun.
Knowledge is to be shared and i am still learning here but this post if solved can help lot of other people maybe.

Thank you.....

Something seems strange here. The input power for a Nano33 BLE is through an mp3610 buck converter. Its Operating input voltage is 4.5V to 21V. It has a under voltage lockout of typical 3.9V. From the schematic, Vin and usb are both connected to the input side of the converter.

What batteries have you tried? Can you run the board from the battery with a simple blink sketch? Is is just the BLE which fails?
