Is it possible to use p0.8,p0.9,p0.10,p0.11 pin as gpio in Ble_app_uart_s110 program of nrf51822?

[Sujith K Sudhakaran]

In nrf51822 Ble_app_uart_s110 program p0.8,p0.9,p0.10,p0.11 can't use as gpio pin. How to configure it ?

[Jørgen Holmefjord]

Hi,

Which SDK version are you using? It is possible to use these pins for GPIO, but note that these pins are used for the UART peripheral on the nRF51-DK. You should change the pins used for UART in the code if you want to repurpose these pins.

Best regards,

Jørgen

Thank you Jorgen

How about nrf52-DK ? Can RX pin be configured as GPIO output for instance

[Jørgen Holmefjord]

You can disconnect the GPIOs from the interface MCU bu cutting SB22-25 on the DK.
