Dear all
I would develop an app to connect 3 Bluetooth modules at once
I this possible?
regards
Stefano
Hello Stefano, welocome to the forum
What would you run the App on? If a Smartphone, you only have one Bluetooth channel, so whilst you can connect to multiple Bluetooth devices, you cannot send-receive simultaneously. Depends on what your Project actually needs to do, amount of data to be transferred etc.
Do you even need three BT modules? If you tell us more detail, we can give better advice.
Use separate Bluetooth components for each connection

Thanks for your reply
I have 1 mobile and i want to receive from 3 module
So 1 mobile 1 module
I will change the project
Tells us about your Project, what is it's goal?
I have 3 BT module
i need to receive numbers from them and change the background of 3 labels
What are the BT Modules attached to - i.e. what microcontrollers are you using? Arduino Uno?
You can receive an integer and process it in approx 100 milliseconds or a bit more, so if you switched between the data sources your labels would be changed inside 1 second - not too bad?
hi
I have 3 arduino with 3 BT hc05 each connected
each of those send 6 values
i want each value on my phone
Well, that's a bit different to the original description - as they say, the devil is in the detail.
Receiving and processing six values takes a little longer than one value, but of course it can be done. So that's eighteen values to display in total?
In order to achieve reliability, it is important to send values over the longest time interval practical whilst still meeting the requirements of the Project. Each Arduino can send a data packet (containing 6 values). Each will need it's own BT Client Block Set in the App.
The interesting thing will be making sure that Arduino_2 doesn't start sending until Arduino_1 has finished sending. The App needs to take charge of that - having received the data from Arduino_1, it can call Arduino_2 to send, then having received the data from Arduino_2, it can call Arduino_3 to send, and so on.
It's going to be good fun to build.
I do not think that this will be necessary... just use separate bluetooth components for each connection

The 3 BT component sets will share the 1 Bluetooth Channel?
