This implements the MTP PTP protocol. This was added with 11.0.0.
capmtp
This is "nn::capmtp::ICapmtpRootSession".
| Cmd | Name |
|---|---|
| 0 | #CreateInterface |
CreateInterface
No input. Returns an #ICapmtpInterface.
ICapmtpInterface
This is "nn::capmtp::ICapmtpInterface".
| Cmd | Name |
|---|---|
| 0 | #Initialize |
| 1 | #Finalize |
| 2 | #Enable |
| 3 | #Disable |
| 4 | #GetConnectionStateChangeEvent |
| 5 | #IsEnabled |
| 6 | #IsConnected |

| 8 | #GetLastError |
Initialize
Takes a u32 max folder count, a u32 max image count, a u32 max video count, a transfer memory handle + u32 size and a type-0x5 buffer translated "Other" utf-16 string.
Finalize
No input/output.
Unmaps transfer memory from #Initialize, stops "nn.capmtp.CapmtpCommandLoop".
Enable
No input/output.
Starts MTP command handler thread "nn.capmtp.CapmtpCommandLoop".
Disable
No input/output.
Stops "nn.capmtp.CapmtpCommandLoop".
GetConnectionStateChangeEvent
No input. Returns readable event handle.
Signaled when the USB connection status changes.
IsEnabled
No input. Returns an output bool.
Returns true if "nn.capmtp.CapmtpCommandLoop" is running.
IsConnected
No input. Returns an output bool.
Returns true if a USB connection is established.
GetUpdatedErrorEvent
No input. Returns readable event handle.
Signaled when an error occurred during album scan.
GetLastError
No input/output.
Returns the album scan Result.
Notes
Only PTP operations 0x1001-0x100A are available.
- OpenSession/CloseSession only allow a maximum of 1 session to be opened.
- DeviceInfo: Serial Number is set to the output from GetSerialNumber. Device Version is set to the SystemVersion DisplayVersion.
While this has access to fsp-srv it remains unused. Images and Videos are loaded with caps:a.
Program names are loaded with ns using the transfer memory from #Initialize.
