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.

IRU is for regular IR comms. The IR hardware operates in the IrDA modulation mode by default, IRU doesn't have an interface for using other modes via hardware.
