clock source for ble _app_uart

[mukesh]

I am running ble_app_uart in my pca10004 board. The crystal configuration is set to 32khz crystal. But i want to use the 16mhz external crystal for my use ,because my application is also running with ble_app_uart code. What clock source is actually this ble_app is using. It will not run if i remove the jumpers for selecting the 32khz crystal. But the pwm example is running fine without the jumpers. How can i enable the ble_app_uart to run only with external 16mhz crystal.

Hi

You could perhaps look at these two threads (1) (2) that describe the low and high frequency clock models respectively. The current consumption guide could also be useful.
