Is there a way to connect or disconnect only the antenna on STM32WB5MMG?

[YKang.5]

Hello

I developed prototype of wearable device using STM32WBMMG, and planning to acquire FCC certification.

​STM32WB5MMG already has FCC ID; YCP-STM32WB5M001; however, it is the certification of the chip itself.

When mounted any kind of devices(PCBs etc.), another FCC certification for device is required.

At this point, for device certification, the Bluetooth antenna should be able to connect or disconnect.

However, STM32WB5MMG is integrated with MCU and Bluetooth module with antena.

Is there a way to connect or disconnect only the antenna?

Thanks.​

Unfortunately, there is no way to disconnect the antenna from the module as the RF connection is in the molding.

Reply above.

Thanks.

Thank you for your reply.

Nevertheless, I want to get new FCC ID for newly developed devices which is using STM32WB5MMG.

​

At photograph 8, the antena(or RF output)is connected to measurement equipment using some kind of connector, and it controlled by USB, I guess.

In conclusion, I would like to know the HW(like above photograph 😎 and FW setting.

Sincerely.​

I understand the picture demonstrated the test of another module and you would like to be able to do the same with the STM32WB5MMG module.

Why do you need to perform conducted tests? ... as the module is already FCC certified.

Hello.

Because, I want to get 'NEW FCC ID' to print it on the 'newly developed devices' to to attend CES.​

You do not need to perform conducted test, radiated test are enough for the FCC when using a certified module on a board.
