CC1352P7: Support Request: Dual Antenna Issue with CC1352P7 BLE Device & Long-Range Optimization

Hello Team,

I hope you're doing well.

We are currently working with the CC1352P7 controller for a BLE-based long-range application, using a design based on TI’s reference schematics. However, we’re facing issues with the dual antenna configuration—the device repeatedly connects and disconnects, and stable operation is not achieved.

To assist in troubleshooting, I have attached our schematic and layout files for your review:

  • We would greatly appreciate it if you could:

  1. Review the schematic and layout for any design-related issues affecting the antenna switching or BLE performance.

  2. Suggest any modifications or best practices to improve the RF performance and enhance the communication range for our long-range use case.

Your expert feedback will help us resolve this issue and move forward with our production goals.

Thank you in advance for your support!
