Hi Paul,

No problem. 🙂 Happy to help.

They can be used for LEDs or switches, just make sure that they do not exceed 10kHz when using the radio. And even though you are not using RF communication or NFC, the BLE utilizes the radio, so disruption can happen.

Hi, Priyanka.

Thank you for your answer.

I'm asking you to check, but is Bluetooth low energy also a kind of radio?

Hi Paul,

Some pins are mentioned as Low drive, low frequency I/O only not because of their capability or because they are connected to rf. It's just that these pins are placed really close to the radio and assigning them as high frequency might interfere with the transmission and reception. It might be possible to assign them as high frequency, but we cannot guarantee the proper working.

Best Regards,

Priyanka
