I have a jailbroken K4.
I would like to have the K4 to act as a digital frame, that autonomously changes the picture it shows after some time passes, e.g., every 30 minutes.
I'm trying an approach based on the screen saver hack.
I have put several images on the K4 and every time I turn it off it shows the next image from the pool.
Now I need to set the K4 to periodically turn on and off to change the screen image. Do you think is it possible?
I searched for a clear answer here and on other websites but I can't find one.
In the case it is not possible, do you think there are other approaches that I can follow to reach my goal?
I would like to find a solution self contained on the device, not using wifi as it will be deployed in a place where it is not possible to connect it to wifi.
For example, can a python script running on the K4 trigger the display of an image saved on the device?
Any hint, suggestion, or link is very welcome.
