Ah, I see. Could you zip your whole application and send it over so I can take a look?

I mean, unless my UE lights up the screen and refreshes the display, the MCU won't be able to receive the gps_handler event message, which is the biggest problem.

I'm sorry I didn't make it clear. The screen I said refers to the screen of the terminal device. When the screen is off, the 9160 will not write data to SPI. When the screen lights up and the 9160 displays data on the screen through the SPI interface, the 9160 receives GPS events

I don't think I'm understanding. Are we talking about your computer screen? Can you just extend the time it takes for the screen to sleep?

Thanks for your reply! The current situation is that when GPS is activated in another thread, the system main thread must have a call to the external device in order to receive the GPS data. Once the screen goes off and the main thread does not send any data to the screen, the GPS data will no longer be received. In fact, the main program can still output other LOG information.

When I press the button, I can receive the data output of the GPS for a short time. It feels like the main program stops for a while before the GPS thread can continue to run, otherwise it will be suspended

Hi!

When your screen shuts down, you don't see the GPS data in the log output? Or does it disappear from the application, as in the information being read from the socket disappears?

The logging can stop when the screen shuts down, so that isn't that strange, but if it's disappearing from the application that's a bigger problem.
