Dear Support,

I am facing some problems on UART0. I am trying to use interrupt method to implement my application using UART. But what I've discovered so far is when the device was Power On, the CC2510 will automatically enter the RX interrupt, even though there were no data that sent to it through UART0. But, when I push the SoC Reset button on SmartRF04EB, it's running fine.

I also did try to debug using IAR Embedded WB using the code downloaded from TI's website, it's has the same result. The CC2510 will enter UART0 RX interrupt upon power up.

If in this case, do I need to apply RESET Circuit on my application?? If it does not, please suggest a way, or please correct me if I'm wrong. Thanking you all in advance.

Thanks and Best Regards,

WH Wong
