CC2543 basic mode operation

Larry,

there is an example for the CC254x Propietary Mode Packet Error Rate Test which can be found at the following link:

Thanks Leo,

I have that app and have been trying to modify it to basic mode. It's presently in auto ack mode.

I'm looking for a quick way to get running in basic mode.

Thanks again.

Larry

Hello Larry, 

We do not currently have any finished code for basic-mode on web. SmartRFStudio uses the devices in Basic-Mode. I would suggest that you start looking at the PER test and trim it down and use register settings from SmartRFStudio. There are a few register you probably need to have different from SmartRFStudio, but if you post questions as you go along we will be happy to answer them.

Hi Erik,

I used the SmartRFStudio setting for my CC2543 transmitter HW & it works well to a SmartRFStudio receiver.

I then put the receive settings into my CC2545 receiver HW & used the Timer2 interrupt routines from the per_test.

The receiver keeps coming out of the TASKDONE with a timeout error. I've listed the code below:

halRfDisableRadio( FORCE ); // Reset LLE (radio).

halRfInit(); // Enable radio in default beacon mode.

halRfConfig( GFSK_250kbps_160khz, RX, 16, PKT_CONF_NRF );

halRfSetFrequency( 2420 );

halRfEnableRadio();

halRfInit(); // Enable radio in Basic mode.

halTimer2SetRadioTimeout( 500, SINGLE ); // Set 500 ms for radio timeout.

halRfEnableInterrupt( RFIRQF1_TASKDONE ); // Enable RF interrupt.

halIntOn(); // Enable global interrupt.

// halTimer2Start(0); // Start timer 2 (asynchronous).

FOREVER
{
halRfStartRx(); // Start receiver.

halTimer2Start(0); // Start timer 2 (asynchronous).

// Wait for TASKDONE and halt CPU (PM0) until task is completed.

while ( !( rfirqf1 & RFIRQF1_TASKDONE ))
{
#if(POWER_SAVING)
halSleepEnterPowerMode( CPU_HALT );
#endif
}

if ( PRF.ENDCAUSE == TASK_ENDOK ) // Task ended without error.
{
if (( rfirqf1 & RFIRQF1_RXOK ) == 1 ) // Check if packet was received.
{
halRfCommand( CMD_RXFIFO_RESET );

length= RFD;

for ( i= 0; i < length; i++ )
{
dataByte= RFD;

Please let me know where the bug is.

Thanks, Larry

Hello Larry,

I think hec is correct. Also make sure not to call halTimer2Start(0); and make sure there are no Timer2 functionality that can interfere with your flow as it seems you are restarting RX operation manually within an infinite loop anyway.

Hi Eirik,

I removed all Timer2 settings and now the code holds at the instruction;

       while ( !( rfirqf1 & RFIRQF1_TASKDONE )) 

I left the interrupt code in;

      halRfEnableInterrupt( RFIRQF1_TASKDONE ); // Enable RF interrupt.

      halIntOn(); // Enable global interrupt.

This looks like a receiver problem, although I have double checked all the settings;

Frequency, modulation etc. and they are the values from SmartRF Studio

any ideas?

Larry
