When sending data, SendIrnop is used when the size is <=0xFC, otherwise SendIrnopLarge is used.

Only one session to either of these services can be open at a time, thus only one process can use either of these services at once. These services interface with hardware services gpio::IR and i2c::IR. The i2c::IR service is used for sending/receiving data.
+
This service was added with [[8.0.0-18]]. Unlike the other IR services, this uses [[I2C]] deviceid 17(this deviceid isn't actually handled by the [[8.0.0-18]] I2C module). This is for the additional [[New 3DS]] HID hardware, this HID data is stored in [[IRRST_Shared_Memory|shared-memory]]. Even with [[9.0.0-20]] IR module still registers+handles this service on both Old3DS+New3DS.

Only one session(two sessions starting with [[8.0.0-18]]) to any of these services can be open at a time, thus only one/two process(es) can use any of these services at once. These services interface with hardware services gpio::IR and i2c::IR. The i2c::IR service is used for sending/receiving data.

IRU is for regular IR comms. IRUSER uses a custom IR protocol(above the physical layer). Both of these services use IrDA-SIR. The IR hardware seems to only support IrDA-SIR, other physical protocols such as the one for TV-remotes are not supported(going by the datasheet linked [[Hardware|here]] for a different IC at least).
   −
IRU is for regular IR comms. IRUSER uses a custom IR protocol(above the physical layer), which is for 3DS<>3DS comms. The IR hardware operates in the IrDA SIR mode by default, IRU doesn't have an interface for using other modes(such as the one for TV-remotes) via hardware.
+
The protocol used with IRUSER involves encryption(?) implemented in software. IRUSER is used for the [[Circle Pad Pro]]. This same IRUSER service uses the New3DS HID hardware when running on New3DS. Note that the main service for New3DS HID is ir:rst, and these two service are mutually exclusive: when one is initialized and reading data from New3DS HID, the other cannot access it.
