Enumerations
enum	sdc_hci_msg_type_t { SDC_HCI_MSG_TYPE_DATA = 0x02 , SDC_HCI_MSG_TYPE_EVT = 0x04 , SDC_HCI_MSG_TYPE_ISO = 0x08 }

Functions
int32_t	sdc_hci_data_put (uint8_t const *p_data_in)
	Send an HCI data packet to the SoftDevice Controller.
int32_t	sdc_hci_iso_data_put (uint8_t const *p_data_in)
	Send an HCI ISO data packet to the SoftDevice Controller.
int32_t	sdc_hci_get (uint8_t *p_packet_out, uint8_t *p_msg_type_out)
	Retrieve an HCI packet from the SoftDevice Controller.

Detailed Description

The SoftDevice Controller HCI APIs are used to send HCI commands/data and receive events/data to and from the SoftDevice Controller. The HCI packet format is described in the Bluetooth Core Specification, i.e. in Core v5. Vol 2, Part E. All APIs in this header file are expected to be called from the same execution priority as mpsl_low_priority_process. Not doing so will lead to undefined behavior.
