Struct Sys

pub struct Sys { /* private fields */ }

A guard that, once constructed, allows for sys commands to be sent to CPU2.

Implementations

impl Sys

pub fn wireless_fw_info(&self) -> Option<WirelessFwInfoTable>

Returns CPU2 wireless firmware information (if present).

pub async fn write(&self, opcode: ShciOpcode, payload: &[u8])

pub async fn write_and_get_response( &self, opcode: ShciOpcode, payload: &[u8], ) -> Result<SchiCommandStatus, ()>

HW_IPCC_SYS_CmdEvtNot

pub async fn shci_c2_mac_802_15_4_init(&self) -> Result<SchiCommandStatus, ()>

pub async fn shci_c2_ble_init( &self, param: ShciBleInitCmdParam, ) -> Result<SchiCommandStatus, ()>

Send a request to CPU2 to initialise the BLE stack.

This must be called before any BLE commands are sent via the BLE channel (according to AN5289, Figures 65 and 66). It should only be called after CPU2 sends a system event, via HW_IPCC_SYS_EvtNot, aka IoBusCallBackUserEvt (as detailed in Figure 65), aka crate::sub::ble::hci::host::uart::UartHci::read.

pub async fn read(&self) -> EvtBox<MemoryManager>

HW_IPCC_SYS_EvtNot

This method takes the place of the HW_IPCC_SYS_EvtNot/SysUserEvtRx/APPE_SysUserEvtRx, as the embassy implementation avoids the need to call C public bindings, and instead handles the event channels directly.
