regarding ble_init_problem

[Mathew A]

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

Hi,

Make sure that you flash the SoftDevice as well. If you add some logging inside of ble_stack_init() that might help to find the issue, e.g. find out exactly what function that is not retuning, or if some of the functions there are returning an error.

This central example created by Torbjørn here might also be useful for your project:

hi thanks for the reply, can you suggest some procedure for flashing the softdevice 140 hex  along with the ble_app_blinky_c code hex . I tried flashing both hex using nrfconnect for desktop, its showing hex files are overlapped but when i press write option the hex file is flashed, but no change in the code.

so please let me know how to flash Softdevice and program hex  to work with ble projects

Thanks.

hi,

  i have changed the address range by following this example

and successfully flashed the hex along with softdevice hex

Thanks for the support
