setting gpio in dfu mode

[xtian]

good day,

is there a way to set a gpio when in dfu mode? wanted to make GPIO 19 of nRF52832 HIGH during DFU mode because we assigned it as an enable pin.

in DFU mode, i obeserved that it is HIGH (LED3 OFF in PCA10040) when device is not connected and LOW (LED3 ON in PCA10040) when device is connected. i wanted it to be HIGH when in dfu mode whether its connected, disconnected or updating.

we used the secure_bootloader example, do we need to change some settings to make it happen?

using nRF52832 (PCA10040) and SDK 17.1

thanks

Hi Kristian, 
I don't see any problem with that. 
You can have a look at the  dfu_observer() function in main.c in bootloader project.

You can see BSP_BOARD_LED_2 (which is LED 3 when you count from 0) being controlled there. You can modify the code there.
