这些时间戳来自终端程序,它们与嗅探器时间戳之间似乎存在一些偏差,但外围设备显然是在响应事件 0x0054 时输出这些时间戳。 请注意,它会立即报告 BLE_HCI_INSTANT_PASSED 原因代码 (0x28) 的连接断开,但在那一刻真正到来之前,它会继续以 ACK 进行响应。 此时,中央切换到新的连接间隔,外围设备停止响应。 所以问题...

I'm getting intermittent disconnections with a BLE_HCI_INSTANT_PASSED reason, when my PSoC 4 peripheral tries to change the connection parameters. The original connection parameters specified in the central's CONNECT_IND are a connection interval of 30ms, a supervision timeout of 500ms, and a...
2.HCI层跟LL层的关系: a. 有些HCI command只是用来设置本地Controller,不导致无线传输 b. 有些HCI command会导致LL层发出各类广播包:比如在主动扫描时会导致LL层发出SCAN_REQ广播包;还有比如会导致LL层发出连接的CONNECT_REQ广播包; c. 有些HCI command会导致LL层发出数据包,其中的LLID=11b,表示是“LL Contro...

always sending continuous data to all connected central devices using notification. If new connection request comes at that time, everytimes connection become unstable and device got disconnected after few seconds with ble error code0x28(BLE_HCI_INSTANT_PASSED) or...
We're seeing an issue where the soft device stops responding and ultimately disconnects with the reason BLE_HCI_INSTANT_PASSED. The disconnection only seems to happen
That way, once it is finally sent out, the instant for which the the new parameters shall be valid lies then in the past. The connection now gets disconnect either with reason 0x08 (timeout) or 0x28 (instant passed). From the sniffer log, the slave has not sync-ed at event...
