hi,
i am testing the ble_app_blinky_c_pca10056 code for the nrf52840 dongle , i changed the board from Pca10056 to pca10059 by following the instruction given in the
nRF52840 Dongle Programming Tutorial
so basic led blink, uart programs work fine but i was trying ble_app_blink_c_pca10056_s140 to establish the Bluetooth connection but nothing works, then i was debugging with uart after commenting the ble_stack_init() some data from the uart is printed, i think the code is getting hanged or halt because of this ble_stack_init(), 

have attached the images, please check
please verify and let me know what is the probelm
