How to implement buzzer in ble_uart_peripheral example

[singh]

Hi,

I am using nrf52 with sdk11.0, I have migrated the code of pwm_library code to ble_uart_peripheral. But when i'm initializing the pwm the code it stops the advertising.Is there an code which works Ble and buzzer at the same time. Please help me.

Thanks&Regards,

Hi, please post initialization part of code. I had the same problem so maybe I can help you.
