Supporting the API
Applications that support the API should make provisions to deal with new API frames
that may be introduced in future releases. For example, a section of code on a host
microprocessor that handles received serial API frames (sent out the module's DOUT
pin) might look like this:
void XBee_HandleRxAPIFrame(_apiFrameUnion *papiFrame){
switch(papiFrame->api_id){
case RX_RF_DATA_FRAME:
//process received RF data frame break;
case RX_IO_SAMPLE_FRAME:
//process IO sample frame break;
default:
//Discard any other API frame types that are not being used break;
}
}
