ERROR: undefined reference to `createBLEInstance()'

[ddavidebor]

white trying to compile source code offline i'm having the same issue over and over again.

it has been similarly reported here https://developer.mbed.org/questions/54408/Build-error/

i'm unable to find where is the problem in the linker, i'm using the 16k S110 version
