Tool/software: TI-RTOS
Hi,
I got the RF settings for the 433MHz@1mbps communication through SVS.
8836.7750.smartrf_settings.c
This setup works fine in the rfpacketTx/Rx and rfEasylinkTx/Rx routines, but not in the RFWsn protocol. Through breakpoint debugging, the program cannot receive after receiving the data once.

while (1) {
uint32_t events = Event_pend(radioOperationEventHandle, 0, RADIO_EVENT_ALL, BIOS_WAIT_FOREVER);

if(events & RADIO_EVENT_VALID_PACKET_RECEIVED) {
/* Send ack packet */
sendAck(latestRxPacket.header.sourceAddress);
/* Call packet received callback */
notifyPacketReceived(&latestRxPacket);

if(EasyLink_receiveAsync(rxDoneCallback, 0) != EasyLink_Status_Success) {
System_abort("EasyLink_receiveAsync failed");
}
/* toggle Activity LED */
PIN_setOutputValue(ledPinHandle, CONCENTRATOR_ACTIVITY_LED,
!PIN_getOutputValue(CONCENTRATOR_ACTIVITY_LED));
}
After the program runs to if(EasyLink_receiveAsync(rxDoneCallback, 0) != EasyLink_Status_Success) { } in if(events & RADIO_EVENT_VALID_PACKET_RECEIVED), status can return EasyLink_Status_Success. When it continues to step through, it finds that it can not enter rxDoneCallback after executing the program to Event_pend().
I don't understand now, EasyLink_receiveAsync can return EasyLink_Status_Success, why the program can't enter rxDoneCallback in event_pend().
