3.2.7 Telink Defined Event
Besides the standard Controller HCI event, SDK also provides Telink defined event, the
architecture is shown below.
In terms of user application, events are from Host and Controller (equivalent to the whole
BLE stack). Most events are from Controller, and will be introduced in this section. The
Host part will introduce a few events from Host.

Figure 3-19 Architecture of Telink Defined Event
Up to 20 Telink defined events are supported, which are defined by using macros in
“stack/ble//ll/ll.h”.
Current new SDK supports the following callback events.
“BLT_EV_FLAG_CONNECT/BLT_EV_FLAG_TERMINATE” has the same function as
“HCI_SUB_EVT_LE_CONNECTION_COMPLETE” and
“HCI_EVT_DISCONNECTION_COMPLETE” in HCI event, but data definition of these
events are different.
