Basic sample when using nRF51 DK board.

[PE-NOWAY]

Hello support team Devzone.

I am new member  and i have a nRF51 DK board.

I try to create hex file for my nRF 51 DK board on the website : Mbed Compiler

when compiler 1 error has occurred : Error: Undefined symbol assert_nrf_callback (referred from /extras/mbed/TARGET_NRF51_DK/TOOLCHAIN_ARM_STD/app_pwm.o).

Can you support me (or show me how to solved)

Thank you so much.

Any particular reason for starting with that? It is rather old...

Note that  nRF51 are not recommended for new BLE designs:

mbed is an independent 3rd party; AFAIK, mbed does not use the Nordic SDK - so you need to go to mbed for support with that
