CC2531EMK: How much time for buffer to clear up.

Hi,

I've realized that after sending multiple commands at once, the AF_DATA_REQUEST_SRSP responds with a 0x11 status; that looking at the zstack.h file it means that the buffer is full.

In my source code (below the code snippet) what I do is: 

• I send the first command.
• Get the status.
• if it's equal to 0x11 it means that the buffer is full, so I just wait for 2 seconds and resend the command.
• And restart from the beginning

But It seems like 2 seconds are not enough for the buffer to empty.

I can't afford to wait for the Data Confirm from the ZED, or any sort of ACK.

public synchronized boolean setSetPoint(int nwkAddr, float temperature)
    {
        int valoreFormatoZStack = (int)(temperature * 100);
        
        int[] pacchetto = DoPacket.AF_DATA_REQUEST_WRITE_ATTRIBUTE( nwkAddr,
                                                                    DoPacket.HVAC,
                                                                    DoPacket.OCCUPIED_HEATING_SETPOINT,
                                                                    valoreFormatoZStack);
        if(!this.writeArray(pacchetto)){
             return false;
        }
           

        boolean status = waitForCommandResponse();

        if(this.lastResponseMessage == 0x11)
        {

            try
            {
                Thread.sleep(2000);
            }
            catch(InterruptedException thError)
            {

                return false;
            }
            
            //Recursive call.
            this.setSetPoint(nwkAddr, temperature);
        }
        
        return status;
    }
