the Keil compiler complains about 'undefined' reference to &att_decl_char?
Where does this declaration come from??
Couldn't find any reference in the project.
How can I resolve this issue?
And is there a full example available to have a central device getting notified by the peripheral
device of a button state? Any help I will appreciate!
