Hello,
I am working with the nrf52832 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 P0.24 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 Ananye,
P0.24 does have a restriction.., Other GPIOs with restrictions may be found on Pin assignment section in table 5 on page 17 of the nRF52832 you will see a list of GPIOs and the restrictions placed on them . Low frequency use only means less then 10KHz.
There is also a requirement for P0.25 and P0.26. If these are used you must place a 12pF to ground on each pin. If these GPIO will not be used you may either continue to use the caps or just ground them.
Those are the restrictions.
Good luck with your project
Best regards,
Jay Tyzzer
