USB not enumerating in example BLE_Central + USB hid

[shaoyang_v]

Hi,

I am trying to merage "ble_app_hrs_c" & "usbd_hid_generic" examples.

After programing, I Insert dongle into USB with SWD , BLE and USB run normaly.

But if i insert dongle into USB without SWD, BLE run normaly, usb hid unable to enumerate. From the log, “APP_USBD_EVT_POWER_DETECTED” “APP_USBD_EVT_POWER_READY”  in “usbd_user_ev_handler” function not running.

My development environment is as follows:

      SDK: v15.1.0_a8c0c4d @ Windows 7 x64

      SD: v6.1.0

      IDE: IAR + JLink

      HW: custom dongle is similar to PCA10059.

I read the following links:

The problem has not changed.

Do you see this issue with the unmodied usbd_hid_generic example ?

Or did this issue appear after you tried to merge the examples?

[shaoyang_v]

The two examples run normally before merging.This problem arises after the merger.
If anyone successfully merged BlE central and usb hid ? I hope you can give me some advice.
Thanks.

You should take a look at how BLE and ble_app_uart is merged in the usbd_ble_uart example.

Hi shaoyang_v,

Did you manage to successfully run this combination without SWD?
