nrf51822 gpio 11 gpio12 twi not working

[Nasib]

Hello i have a working program with ble:uart and twi in a nrf51822 device with sdk 12.3 and softdevice

My system works perfectly when i use other gpio as scl and sda (external pull up resistors)

But when i want to use gpio 11 and gpio 12 the twi is not working. Also in this scenario the BLE is not working too

What could be happening here ??


Thanx a lot!

Hi,

Are you able to use TWI and other GPIO and everything works... but when you try to use p0.11 and p0.12 then suddenly it does not work ?

Are you using other features that use the same base address ?


Regards,

Finally it is working. P0.11 was used for UART. Purposes. So I just redefine UART pines . 

Thx
