hi professor,

In the uart interrupt I call k_fifo_put to trigger rx process thread but it is not take effect.What person cause this question?

Hello,

Have you verified through debugging that k_fifo_put() actually gets called?

Thanks,

Vidar

I'm sure k_fifo_put was called.

According to the link, I use the "IRQ_CONNECT(SPIM0_SPIS0_TWIM0_TWIS0_UARTE0_IRQn, 0, nrfx_isr, nrfx_uarte_0_irq_handler, 0)" to init uart irq.But the problem remains.

Thanks for confirming. But I'm afraid I can't think of anything else that can cause this behavior. Are you able to share the rest of your code or create a minimal sample that will allow me to reproduce this here?

Edit: Can you show the struct declaration for sensor_operate_t ?

typedef struct
{
void *fifo_reserved;
uint32_t uiSensorState;
}sensor_operate_t;

I'm unable to extract your *.rar file for some reason. Could you please try to upload it again and maybe as a .zip instead?
