即时通过错误

你好，
即时通过的错误代码表明，不能执行LMP PDU或LL PDU（例如LLXCONNECTIONUPDATEY Req PDU用于改变连接参数），因为该时刻已经发生。
因此，例如当主机发送这个PDU（LLyCalnFixUpDeaTeE.ReqPDU）时，它将作为这个PDU的一部分发送一个即时值。
当应用更新后的参数时，LLSCONNECTION-UpDATEYRE PDU的瞬时字段将被用来指示CONNEN计数，这被称为“即时”。主人应该允许至少6个连接事件，奴隶将在瞬间发生之前监听。
希望以上清除错误信息。
现在解决这个问题——
在BLE连接建立之后，你是否正在改变连接参数？如果是，检查从潜伏期数你用的是什么。尝试较少数量的从属延迟（例如0）。

你使用的是哪个BLE设备？如果你正在使用一个模块解决方案（cyble- xxxxxxx -xx）的一部分，为生态正确盖调整值按下面的文件-生态电容值ez-ble修剪™模块- kba218990

  Hello,
 
 
The Instant Passed error code indicates that an LMP PDU or LL PDU  ( for example LL_CONNECTION_UPDATE_REQ PDU for changing the connection parameter ) that includes an instant cannot be performed because the instant when this would have occurred has passed.
So, for example when the master sends this PDU (LL_CONNECTION_UPDATE_REQ PDU), it will sends an instant value as a part of this PDU.
The Instant field of the LL_CONNECTION_UPDATE_REQ PDU shall be used to indicate the connEventCount when the updated parameters shall be applied; this is known as the instant. The master should allow a minimum of 6 connection events that the slave will be listening for before the instant occurs.
 
Hope above clears about the error message.
 
Now to resolve this issue --
 
-> Are you changing the connection parameters after the BLE connection has established ? If yes, check what is the Slave latency number you have used. Try with a lesser number for slave latency  (eg. 0)
 
-> Are you using the Low Power Modes in your design and also changing the WCO Sleep Clock Accuracy? If yes , please refer the page #12 for correct configuration from this document -http://www.cypress.com/file/140991/download
 
-> Which BLE device are you using ? If you are using a Module solution ( CYBLE-xxxxxxx-xx) part , assign the correct cap-trim values for the ECO as per the below document - ECO Capacitance Trim Values for EZ-BLE™ Modules - KBA218990
