I have cloned the BLE code from the periperal_uart example provided in the SDK. However, I am using C++ so I am perform my BLE initialization inside a .cpp file (i.e. main.cpp). The problem is how the SDK's internal BT_LE_ADV_PARAM_INIT() macro expands when calling the bt_le_adv_start() method. The macro generates an invalid C++ construct - see the compiler error below. And yes - I have tried moving the offending code to a C file - and it compiles. However, I am not comfortable with this work around since while it compiles - I am not sure the actual generated code will be valid for C++ app (because the array made not really be in scope even though it compiled under my hybrid .c/.cpp files).
Is this a know bug with the SDK? If yes - is there a timeline for a fix?
