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, calling WM_SetMPData() repeatedly without waiting for callbacks processes even if different function pointers are specified for callbacks.
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.
callback |
Pointer to the callback function to call when the asynchronous process completes. |
sendData |
Pointer to the data to be send-reserved. Notice that this data entity will be forcibly cached. |
sendDataSize |
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 process result as a WMErrCode enumerated type.
