Hello Choi,

Happy to help. When your final design will be done you can send us schematic and layout design. We provide review on these.

Best Regards,

Hello Kazi Afroza Sultana,

Thank you so much for your advice.

Actually, as a mobile app developer, there is a limit to improving BLE performance, so I asked this question.

Thank you so much for helping us make great products.

Hello Choi,

Your schematic shows only the matching network for RF, you do not have any matching network for antenna. And Vss pin is also not properly grounded.

you can look at our schematic design how VSS pin is grounded. It is grounded through capacitor C3.

I think the performance is not optimal due to the pcb design. You need to tune the antenna for best performance. Here we only can see the length and width of the antenna but do no know the trace width and copper thicknesses. There is also a led near antenna it is not ideal.

So, you may re-look the design from this point of view.

Thanks. Feel free to ask if you have more questions.

Have a nice weekend.
