About mixed use of Arduino UNO and CC2530 [Copy link]

Since I need to use two boards and Arduino is easier to use, I plan to use a combination of Arduino and CC2530. However, I am new to this and don't know much about serial communication and wireless communication modules, so I plan to use IO directly for signal transmission. However, after I adjusted the Arduino, I found that CC2530 could not receive any signals, and even the ground pin of CC2530 connected to Arduino could not get a low level. So is there anyone who can give me some advice or explain this problem?

Arduino and CC2530 communicating via SPI is a better solution.
