Using a Nextion display with Bluetooth through an Arduino

Other Hardware Displays
1

Hello, I recently began a project where I essentially want to be able to connect my phone to a screen and change the image to the exact pre-set image I want. I have it set up so far that I can touch the screen and go through all of the images in order, but I would really like to be able to pick them out specifically.

I was wondering if it is possible to hook up a Bluetooth module to an Arduino uno and then connect that to the Nextion? I would want the phone to send simple info on which image to pull up (like maybe a digit? There are only around 7 images I would want to use) and then the Arduino to send information to the Nextion display so that it can pull up and display the proper image.

If there is a better place to post this please let me know.

Thank you for any help you may have to give!

Assuming you have a spare serial port for the Nextion and a suitable port (I don't know what you need) spare for the bluetooth module this should be possible.

I would want the phone to send simple info on which image to pull up (like maybe a digit? There are only around 7 images I would want to use) and then the Arduino to send information to the Nextion display so that it can pull up and display the proper image.

Assuming you can get the phone to Arduino part working the Arduino to Nextion part is easy.
