[SOLVED] Connect multiple HC-05 to a computer

[naxmouk]

Hello everyone !

In my project I would like to receive the data of multiple HC-05 bluetooth module on a computer.
For that I will use a USB dongle because the computer doesn't have bluetooth.
Is it possible to acquire the data of various HC-05 simultaneously ? For exemple, I would like to show the data on Labview.

Thanks !

Computers can manage multiple Bluetooth connections so I believe the concept is valid.

The details may make the project cumbersome....

HC-05 - does the following link show the module you are planning to use?

https://components101.com/wireless/hc-05-bluetooth-module

I do not have an answer per se. However, I believe more information is needed regarding your project.

What sort of data are you collecting and what software will you be using to manage data collection, processing, and display?

Host computer: hardware specs and OS?

Include more information and hopefully there will be other more direct suggestions and ideas.

Thank you for your answer,

Indeed, this link shows the module that I will use.

I have a DHT22 (temperature and humidity) sensor and a HC-05 bluetooth module connected with an Arduino Uno. With the HC-05 I'm planning to send the data of the sensor to the computer. After that I'm planning to do a Human Machine Interface on Labview to show the data of the sensor.
I want to have multiple [sensor+Arduino+HC-05] sending data to a computer. I will use a USB dongle for that but I don't know if it's possible to acquire the data of numerous HC-05 simultaneously.

The computer has Windows 10.

Good starter link:

https://www.thetechlounge.com/best-bluetooth-adapter/

Your basic question, as I understand it, is how many devices can be simultaneously and successfully paired with the Bluetooth adapter and how is that done.

Going out of my comfort zone somewhat but the following link should prove helpful:

https://avantree.com/product-support/BTDG-40S-BLK

Not promoting nor endorsing Avantree - it is just that that link condenses a lot of useful information - note the FAQ section.

What software do you intend to use or are you writing your own code?

Thanks !
I checked the link of the Avantree Bluetooth adaptater, it's what I plan to use. And yes I'm wondering if I can process the data of 5-6 devices (HC-05) with one adapter.

I will use Arduino IDE for the sensor's data acquisition/bluetooth emission and Labview to receive and show the data.

Bluetooth has limited range compared to standard WIFI. Why not use WIFI? There are Arduino Uno versions with WIFI built-in.

Yes I could use that but the problem is the same no ? How can I connect multiple wifi devices to my computer ?

WIFI is EASY. You setup a stand-alone WIFI router, you connect to that network via ethernet and ALL your devices are available via IP. No-muss no-fuss.

Okay ty !
I'm a beginner in wireless transmitions so I'm kind of lost ahah

You will just need to configure LabView to use ethernet to connect to the "instruments".
This page has some basics -- https://www.ni.com/en-us/support/do...06/basic-tcp-ip-communication-in-labview.html

I did a project at work where I had about 50 temperature sensors connected via ethernet to a laptop. I only sampled the temps every 30 seconds, because this experiment ran for months. One thing to remember, for any sampling experiment like this you want accurate time (assuming you need to correlate things). I used a USB GPS receiver to get time to the laptop, since it was not connected to any public network.

Ok ty ! So I need to configure the Arduino uno wifi to connect to the router and then I need to connect the router via ethernet. And my computer will be able to "see" the router
