Hi.
I am using nRF52840 Dongle.
A problem occurred while merging the PIN_CHANGE_INT examples based on the BLE_APP_BEACON example.
I connected the external button to the breadboard. pins (0,24) and buttons, buttons and GND.
The device is restarted when a gpio signal is detected during advertising.
In the code below, LED2_R is lit when executed. LED2_G and a beacon signal turns on when the external button is pressed.
However, when the button is released, LED2_R turns off and on, and LED2_G does not turn on.
To check, All rows related to LEDs in bsp.c. have been annotated.
How can I solve this problem?
