Undefined symbol nrf_ecb_init()

[Alex Co]

Hi

I am working with mbed targetting for ReadbearLab Ble Nano. I am trying to encrypt payload before sendind it with:

include "nrf_ecb.h" ...

int main(void) { ... nrf_ecb_init(); nrf_ecb_set_key(key);

But I see:

Undefined symbol nrf_ecb_init() (referred from main.RBLAB_BLENANO.o).

(I can compile and deploy other kind of programs targeting Ble nano.)

Hence it seems that @ linker stage there is no nrf_ecb.o.

Do I have to include any lib or c file by hand?

Using mbed

Thanks

Alex

Hi Alex. Sorry for the late response, not many people internally have much mBed experience. I am trying to find someone that can help with this, and will get back to you as soon as I do.

It looks like this is caused by call of C function from C++ code. See: developer.mbed.org/.../

Resolution:

extern "C"
{
   #include "nrf_ecb.h"
}
