I have a 5’’ nextion screen from a client (So I do not know the model he bought).
It says NX8048T050_011 in the pcb.
After loading the latest firmware with the latest IDE it says that it is “R(No touch)”: NX8048T050_011R(No Touch),firmware Ver:S150
I think he never tested the touch screen as the application he needed to use only required to show data on the screen.
As I have found, there is an R model and a N model. This is supposed to be an R but I have never seen the “No touch” comment in this devices.
Is it possible that touch pannel is broken?
I have tried to send the command “touch_j” by serial port but nothing happens. In other screens, it starts the calibration process.
