广播包被封装在LL层packet中的PDU中,由Header和Payload两部分组成,是GAP协议管理的内容; 1.Header部分(16bits); 1)PDU Type: PDU Type为4bit,具体定义如下。可以看出扫描PDU和发起连接PDU都属于广播包。 实际工作中用的较多的是ADV_IND、ADV_DIRECT_IND、SCAN_REQ、SCAN_RSP、CONNECT_REQ。 ---ADV_IND 普通...

sd_ble_gap_adv_stop() I have a beacon type running firmware. My system should start advertising when I press button A. and then stop when I press button B. So here is the scenerio: Scene 1:Press button A(ok), press button B(error/restart) ...
