Hello everyone,
Transmit and Receive data rates have a difference of exactly /2. I do my calculations like this:
- 1second timer is installed on both systems.
- callbak interrupt is defined in my RF_runCmd command. and this callback function is processed when the send/receive is completed.
- I collect the received and sent data in a variable every time a callback is invoked.
- I divide these values collected every 1 second by the constant dt and multiply by 8 to convert them to bits.
- In the results, transmit is found at 1mbits, while rx remains at 500kbits. And this rate is always the same.
I cannot receive exactly as much data at the receiver as I sent. And there are serious losses. receive_thread are given below:
Receive_thread;
static RF_Object RFObject;
static RF_Handle rfHandle;
static rfc_dataEntryPointer_t rxEntry;
static dataQueue_t dataQueue;
static rfc_dataEntryGeneral_t *currentDataEntry;
uint8_t packetLength;
uint8_t *packetDataPointer;
void *rf_receiverThread(void *arg0)
{
RFQueue_defineQueue,rxDataEntryBuffer,sizeof(rxDataEntryBuffer),NUM_DATA_ENTRIES,MAX_LENGTH+NUM_APPEND_BYTES));
RF_cmdPropRxAdv.pQueue = &dataQueue;
RF_cmdPropRxAdv.rxConf.bAutoFlushIgnored = 1;
RF_cmdPropRxAdv.rxConf.bAutoFlushCrcErr = 1;
RF_cmdPropRxAdv.maxPktLen = MAX_LENGTH;
RF_cmdPropRadioDivSetup.formatConf.bMsbFirst = 0;
RF_cmdPropRadioDivSetup.formatConf.whitenMode = 0;
rfHandle = RF_open(&rfObject, &RF_propFs, RF_PriorityNormal, NULL, 0);
RF_postCmd(rfHandle,(RF_Op*)&RF_cmdFs,RF_PriorityNormal,NULL,0);
while(1)
{
RF_runCmd(rfHandle,(RF_Op*)&RF_cmdPropRxAdv,RF_PriorityNormal,&callback,RF_EventRxEntryDone);
}
void callback(RF_handle h,RF_CmdHandle ch, RF_EventMask e)
{
if (e & RF_EventRxEntryDone)
{
currentDataEntry = RFQueue_getDataEntry();
packetLength = *(uint8_t)(¤tDataEntry->data);
packetDataPointer = (uint8_t *)(¤tDataEntry->data+1);
memcpy(packet,packetDataPointer,packetLength+1);
RFQueue_nextEntry();
// todo: calculation data_rate += packetLength;
}
}
}
