Hi All,
I have created a custom board header file based off of the pca10040.h file. I have customised this to support 10 buttons and 2 leds. I have also extended the array app_button_cfg_t app_buttons[BUTTONS_NUMBER] in bsp.c to support the 10 buttons and bsp_event_t to include BSP_EVENT_KEY_8 and BSP_EVENT_KEY_9. I have also set the number of GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS to 10 in sdk_gonfig.h. My code is based on extending the ble_app_template to include a custom service and this all works.
I have setup a timer with a notification interval of 20ms (50Hz) to send 4 bytes during each notification. The first 2 bytes are analog data and the last two bytes are button states from 9 buttons.
Before enabling the notifications from a central device, the bsp_event_handler catches every button press perfectly (checked it on a scope). However, when i enable notifications at this data rate, i am unable to catch the disconnect button (long press) or any of the 9 other buttons properly, or at all.
What can i do to resolve this?
Cheers,
