Create the Nordic Status Message Service instance.

This macro creates the Nordic Status Message Service instance and prepares it to work. Note that it allows to implement multiple instances and the only difference between them would be the name.

Parameters

_nsms	Name of Status Message Service instance.
_name	NULL terminated string used as a CUD for Status Message Characteristic.
_slevel	Security level to use the characteristic. BT_NSMS_SECURITY_LEVEL_AUTHEN - requires authentication BT_NSMS_SECURITY_LEVEL_ENCRYPT - encryption is sufficient BT_NSMS_SECURITY_LEVEL_NONE and other values - none
_status_init	Initial message.
_len_max	Maximal size of the message. The size of the message buffer.
