Pin configurations for bluetooth

[Ananye]

Hello,

I am working with the nrf52840 chip and wanted to know if there are any pins that are shown on the schematic diagram, that I should not use to ensure that the Bluetooth functionality continues to work.

For example, lets say I want to use a pin P1.12 for my project. Will using that lead to a problem with the Bluetooth functionality of the chip? Similarly, are there any other pins I should not use.

Thanks

Hi,

Please refer to the Pin assignments documentation for the package type you are using.

All pins can be used, but some of the pins are marked "Standard drive, low frequency I/O only". This should be respected to make sure that the radio performs well and according to specifications.

Best regards,
Jørgen
