Hi all,
I am using the STM32WB55CEU6 to share data using BLE technology. I have designed a customized PCB based on my requirements. I fully configured the STM32CubeIDE .ioc file according to ST’s reference documents. However, I am not getting any output — the BLE device name is not showing up in the ST BLE Toolbox application. I am not sure what the exact problem is in my case. Below, I have attached my schematic design and RF part in my design
Note: Polygon is applied on my RF part,if it is correct?.
I have one question:
When I checked the IC before mounting it onto my PCB, I noticed that Pin 21 (RF1) and Pin 49 are internally connected. Is this normal? In some reference designs, Pin 49 is connected to GND, and I have also connected it to GND. Which one is correct?
Can anyone please help me solve this problem? Thank you in advance for your responses.
