你跟进"NRF_SDH_BLE_OBSERVER"这个宏看,他这个宏函数已经定义了:
#define NRF_SDH_BLE_OBSERVER(_name, _prio, _handler, _context) \
STATIC_ASSERT(NRF_SDH_BLE_ENABLED, "NRF_SDH_BLE_ENABLED not set!"); \
STATIC_ASSERT(_prio < NRF_SDH_BLE_OBSERVER_PRIO_LEVELS, "Priority level unavailable."); \
NRF_SECTION_SET_ITEM_REGISTER(sdh_ble_observers, _prio, static nrf_sdh_ble_evt_observer_t _name) = \
{ \
.handler = _handler, \
.p_context = _context \
}
