callback |
Designates the callback function to call when the asynchronous process completes. This callback is called from within the interrupt handler. |
sendData |
Pointer to the data to be send-reserved. Note that this data is forcibly cached. |
sendDataSize |
The size of the send-reserved data. |
tmptt |
Kept to maintain backward-compatibility — now it is ignored. |
pollbmp |
Bitmap that indicates the AID of the send destination child. (enabled only for the parent). |
Returns the results of the WMErrCode enumerated type process.
Sets the data to be sent by the MP This function is only executable when the WM is in either the MP PARENT or MP CHILD state. If the return value is WM_ERRCODE_OPERATING, a callback is generated after the MP completes the data transmission process. Do not rewrite the buffer identified by sendData until the callback is called. Unlike the asynchronous functions of other wireless APIs, processing continues normally even if different function pointers are specified for callbacks when this API is called repeatedly without waiting for callbacks. However, you can call this function a maximum of 10 consecutive times without waiting for a callback; if this function is called more than 10 consecutive times, the API returns an error.
This function was retained from previous versions to maintain backward-compatibility and is equivalent to specifying WM_PORT_RAWDATA for port and WM_PRIORITY_NORMAL for prio in WM_SetMPDataToPort.
The sendData argument is forcibly stored in the internal cache. To avoid overwriting surrounding memory regions, be sure to pass data that is 32-byte aligned.
See the Wireless Communication Library Manual (AboutWirelessManager.pdf) for additional details.
