Function Documentation

uint16_t hciDrvRead ( uint16_t  len,
uint8_t *  pData 

Read data bytes from the driver.

lenNumber of bytes to read.
pDataByte array to store data.
Return actual number of data bytes read.
bool_t hciDrvReadyToSleep ( void  )

Returns TRUE if driver allows MCU to enter low power sleep mode.

TRUE if ready to sleep, FALSE otherwise.
uint16_t hciDrvWrite ( uint8_t  type,
uint16_t  len,
uint8_t *  pData 

Write data the driver.

typeHCI packet type
lenNumber of bytes to write.
pDataByte array to write.
Return actual number of data bytes written.
The type parameter allows the driver layer to prepend the data with a header on the same write transaction.
