To find out where the fatal error occurs, you can set a breakpoint in the error handler (APP_ERROR_CHECK) and at hardfault. If one of those breakpoints are hit when running in debug mode, you can take a look at the call stack to see where the problem originates from.

Okay, im getting a fatal error. my UART initialization does not work. i will post all (to my knowledge) related code:

Main: https://pastebin.com/Yq978hAS

nus_c_init: https://pastebin.com/NJTEjNR2

uart_init https://pastebin.com/BzjuVhQJ

uart_eventhandler: https://pastebin.com/sMGyMdRU

ble_evt_dispatch: https://pastebin.com/mRJbRzL4

that should be everything relevant. i lack the experience to tell where the problem arises. so i would be really glad if you could help me out :)

Upon an advertising report (receiving an advertising packet), the ble_multilink_central example will filter on device name while ble_app_uart_c will filter on UUID. I would recommend you to compare the behavior upon "BLE_GAP_EVT_ADV_REPORT" for those two examples.

hi kristin,

thank you for your reply.

i tried following the points you mentioned in that answer, but at the moment it is not working yet.

my code is the following: (it compiles fine but UART apparently is not working. not sure about BLE)

main.c

i think i followed all the steps you mentioned in your linked answer.

This answer explains what I think is the easiest way to have multiple peripherals with ble_app_uart_c.
