[4.0.0+] Connect now takes an additional 4-bytes of input.

[5.0.0+] Cmd24 now returns a total of 0x58-bytes of output instead of 0x5C.

[7.0.0+] Input/output for cmds 27/28 were swapped, perhaps these cmds were swapped?

OpenMode

No input/output.

Sends command message 0x99 to the state machine.

CloseMode

No input/output.

Sends command message 0x9A to the state machine.

GetMacAddress

No input. Returns an output #MacAddress.

Sends command message 0x18 (GetMacAddress) to the state machine.

StartScan

Takes a type-0x15 input buffer buffer containing a #ScanRequest. No output.

Sends command messages 0xA (SetWlanInterfaceUpDown) and 0x14 (ScanRequest) to the state machine.

StopScan

No input/output.

Sends command message 0x16 (CancelScan) to the state machine.

Connect

Takes an input #ConnectParam. No output.

Sends command messages 0xA (SetWlanInterfaceUpDown), 0x11 (SetBeaconLostTimeout) and 0x20 (JoinNetworkSta) to the state machine.

CancelConnect

No input/output.

Sends command message 0x23 (CancelJoinNetwork) to the state machine.

Disconnect

No input/output.

Sends command message 0x24 (DisconnectRequest) to the state machine.

GetSystemEvent

Takes an input u32 SystemEventType. Returns an output Event handle.

GetConnectionStatus

No input. Returns an output #ConnectionStatus.

GetState

No input. Returns an output #State.

Sends command message 0x80 (GetState) to the state machine.

GetScanResult

Takes a type-0x6 output buffer containing a #ScanResult. No output.

Sends command message 0x15 (BssInfoListGet) to the state machine.

GetRssi

No input. Returns an output u32 Rssi.

Sends command message 0x2E (GetRssi) to the state machine.

ChangeRxAntenna

Takes an input u32. No output.

Sends command message 0x30 (SetRxChain) to the state machine.

GetFwVersion

Takes a type-0xA output buffer containing a #FwVersion. No output.

Sends command message 0x33 (GetFwVersion) to the state machine.

RequestSleep

No input/output.

Sends command messages 0x24 (DisconnectRequest), 0x34 (RequestSleep), 0x3D and 0x3E to the state machine.

RequestWakeUp

No input/output.

Sends command messages 0x1 (InitalizeWlanDriver), 0x24 (DisconnectRequest), 0x35 (RequestWakeUp), 0x3E, 0x80 (GetState) and 0x81 (GetStateBeforeSleep) to the state machine.

ConnectWithWps

Takes a type-0x9 input buffer containing a #WpsPin and two input u32s WpsMethod and BeaconLostTimeout. No output.

Sends command messages 0xA (SetWlanInterfaceUpDown), 0x11 (SetBeaconLostTimeout) and 0x21 (JoinNetworkStaWithWps) to the state machine.

Cmd18

No input, returns an output u32.

Sends command message 0x80 (GetState) to the state machine, to check current state. Sends command message 0x36 to the state machine to get a value from state, which is then passed to a vfunc call. That func checks bits in the input to determine what value to return, which is then written to the output u32.

This is not used on retail.

Cmd19

Takes a #MacAddress, 3 u16s, 3 u32s, no output.

This copies the input data into state, and sets a flag in state. The input is written into state with the following structure: #MacAddress, u32[0], u32[1], u16[0], u16[1], u32[2], u16[2].

This data is used during RequestSleep if a state field is set for using it (the codepath using this will throw an error if this data was not set). This data is cleared afterwards regardless of whether it was used. This is used for configuring various config related to wowl/tcpka/etc (wake-on-WLAN/TCP keep-alive). Note that an error is thrown if "wowl_activate" isn't set but sysmodule-side doesn't do so - this seems to be set automatically at some point.

This is used by nifm.

Cmd23

Takes an input u32, no output.

Sends command message 0x38 to the state machine. This is handled by writing the input value into a global flags field. The default value is 0x3 (all flag bits set). These flag bits are checked during the RequestSleep code handling the state for #Cmd19.

This is not used on retail.

Cmd25

Takes two input bools, no output.

When the first bool flag is set, sends command message 0x3B to the state machine. When the second bool flag is set, sends command message 0x3C to the state machine. Then 0 is returned.

Both requests are handled by clearing various data in state.

This is not used on retail.

Cmd26

No input/output.

This sends a request which sets a global flag.

This flag is eventually checked by code which runs via RequestSleep, and in one case with wlan:dtc cmd19 (also used by requests done by nnMain).

This is not used on retail.

Cmd27

Takes a type-0xA output buffer containing an array of 2-byte entries, returns an output u32 total_out.

This memcpys data from state into the output buffer, clamped to a maximum of 0x40 entries (nifm hard-codes the count to 0x26).

This is used by nifm.

InitializeWlan

No input/output.

Sends command message 0x1 (InitalizeWlanDriver) to the state machine.

FinalizeWlan

No input/output.

Sends command message 0x2 (FinalizeWlanDriver) to the state machine.

Cmd30

Takes an input s32, no output.

The input s32 must be <=0xE10 (3600) and >= -1. The input value is written into state, then this returns 0.

The user-process code using this cmd also has the above bounds check.

This is used by wlan during RequestSleep from the same code using the state set by #Cmd19.

This cmd is used by nifm with a value from state, prior to using RequestSleep.

Cmd38

Takes an input u32 enum, no output.

The input value must be 0-1.

This internally sends a request which is then eventually handled (if the input doesn't match state already + other state fields are valid) by configuring "pm2_sleep_ret_ext" with a global struct selected via the input value. Afterwards another func is called with input value 2.

This is used by nifm.

wlan:lcl

This is "nn::wlan::detail::ILocalManager".
