I'm new here, and I am trying to build a smart remote for my bedroom. I already have an Arduino Uno controlling my lights and some fans, with more upgrades coming soon, and I would like to control it via Bluetooth using my 3.2" nextion enhanced.
To keep my nextion "remote" compact, I was wondering if it is possible to connect a Bluetooth module such as the hc-05 directly to the nextion enhanced, through its I/O ports. Another hc-05 module would then obviously be connected to the Arduino, enabling it to receive the data.
So is it possible? Or do I need another microcontroller between the Bluetooth module and the nextion? Thanks in advance to everyone willing to help, I'm still a beginner with this wonderful smart display :)

Your proposed solution is impossible to achieve. You will need a uC to process touches from Nextion and then send commands over Bluetooth.
