Parameters

chan One of the WPAD_CHANn values.
buf Start address of the buffer storing audio data.
len Size of the audio data. A size from 1 to 20 bytes can be specified.

WPAD_ERR_NO_CONTROLLERThe connection was broken.
WPAD_ERR_BUSYThe WPAD library did not accept the command.

Description

Sends audio data of 1 to 20 bytes in length to the Wii remote on the specified channel. Because the Wii remote can play 4-bit, 6-kHz audio data, be sure to send 20 bytes of data every time interval given by WPAD_STRM_INTERVAL.

This function registers the command used to send audio data to the library. The WPAD library processes registered commands when other commands are not running. The processing result of the command for sending audio data registered using this function cannot be obtained.
