Communications with this device is done via the [[IR_Services|ir:USER]] service, which uses obfuscation implemented in software. The [[IRU:SetBitRate|bitrate-value]] passed to IRUSER is 0x04, hence the actual bps is 96000. | Communications with this device is done via the [[IR_Services|ir:USER]] service, which uses obfuscation implemented in software.

The application sends requests via [[IRUSER:SendIrnop]] and receives response from Circle Pad Pro via [[IRUSER:ReceiveIrnop]] (or read data from the [[IRUSER_Shared_Memory|shared memory]]). The request and response data structures below are payloads in packets. | |||
