Hi Lior

Did you ever find a solution to this issue? I'm trying to do the same thing as you, and am running into the same issue.

OK -

In all the USB examples USB events are detected by polling (polling task),

My application works with a battery (softdevice is also active) so I cannot poll USB event all the time,

So, my question is, when softdevice is active - the only way to handle USB events is by polling them?

In the softdevice dpecification 1.1 it says that if softdevice is enabled - power interrupts won't rise to the application - while USBD events will,

I noticed that USBD and power events are somewhat connected - can you please clarify?

Currently, USB does not work for me when softdevice is enabled - I'm not polling the event with a task - I'm handling the interrupts - please clarify the issue...

Regards,

Lior.

Hi, did you look at the usbd_ble_uart example in the SDK? http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/usbd_ble_uart_example.html?cp=4_0_0_4_5_49_1

This shows how to use USB and softdevice together.
