Controlling an arduino from multiple devices

I’m pretty new to this and I was wondering if it is possible to control an arduino connected to an ESP, via multiple mobile phones which have blynk installed at the same time, Is there a way to build a gui and have a number of people access the gui to control the outputs of the arduino.

Hello. Yes. This is possible.

can we use multiple mobile phones yet a time.???

Hello, this is a very old topic. But to answer, yes, follow the link already provided.

You can also simply log into each phone with the same credentials. I use many phones, tablets and emulators that way. As far as the server knows, they are all the same phone/app.

Any further questions, please create a new topic with details about your specific equipment and issues.

Thank you.
