BLE Sleep Clock Accuracy(SCA) for the local device is used to estimate window widening in BLE

|
|
connection events. With a lower level of clock accuracy(e.g. 500ppm over 250ppm), the slave

increase of power consumption but a higher level of robustness in keeping connected. According

The full scan function is mainly used to provide BLE scan performance.

This is required for scenes with high scan performance requirements, such as BLE Mesh scenes.

advertising reports will be discarded by the controller if the number of unprocessed advertising

The number of unprocessed advertising report that Bluedroid can save.If you set

`BTDM_BLE_ADV_REPORT_FLOW_CTRL_NUM` to a small value, this may cause adv packets lost.

|
If you set `BTDM_BLE_ADV_REPORT_FLOW_CTRL_NUM` to a large value, Bluedroid may cache a
|
||
|
|
lot of adv packets and this may cause system memory run out. For example, if you set
|
||
|
|
it to 50, the maximum memory consumed by host is 35 * 50 bytes. Please set
|
||
|
|
`BTDM_BLE_ADV_REPORT_FLOW_CTRL_NUM` according to your system free memory and handle adv
|
||
|
|
packets as fast as possible, otherwise it will cause adv packets lost.

When adv report flow control is enabled, The ADV lost event will be generated when the number
|
||
|
|
of ADV packets lost in the controller reaches this threshold. It is better to set a larger value.
|
||
|
|
If you set `BTDM_BLE_ADV_REPORT_DISCARD_THRSHOLD` to a small value or printf every adv lost event, it
|
||
|
|
may cause adv packets lost more.
