CC3135: Chip application issues

Part Number: CC3135

Hi Team,

I encountered the following problem while debugging cc3135:

We use SOP0 and SOP1 as the control pins for 5Gwifi TX and RX switching.

But when we tested 5GWIFI, we found that when the MCU maintained communication with CC3135, the output levels of SOP0 and SOP1 were 92mv.

What is the reason for this phenomenon? Is there any configuration that has not been done? How to solve these problems

However, when the communication between the MCU and CC3135 is disconnected, and the PC is connected to the EMU small board, and the EMU small board is connected to the CC3135 (the connection ports are TX, RX, GND, NHIB, RTS, CTS), the output levels of SOP0 and SOP1 are 3.3 v.

Best Regards,

Galaxy
