About the poll rate of end device

Hi Licheng,

You can use NLME_SetPollRate(), NLME_SetQueuedPollRate(), and NLME_SetResponseRate() to change polling rate, queuedpollrate and resplonsepollrate of end device anytime when you need to.

Thank you,but i am using the CC2530ZNP spi interface in the design,does the ZNP support the NLME APIs?As far as i know,it only supports the simple API,AF API and ZDO API.

Regards.

Thanks,

but it seens that this only will take effect after resetting the ZNP chip or restarting the ZSTACK,not immediately.

Regards.

Dirty Harry,

thank you very much,i will check the znp codes and have a test about this!And i will be back and verify your answer if it works well.Thank you!

Regards.

Hello Harry,

I had done the simple test,but the result is that it seens the codes didn't take effect.

My simple codes is something like these:

      if((*recvBuf).msgData[4]=='A')
      { 
        setPollRate(10);      
      }

     else if((*recvBuf).msgData[4]==B')
      { 
        setPollRate(1000);      
      }

I am sure when in running and the ((*recvBuf).msgData[4]=='A') is TRUE,the ‘setPollRate(10)’ had been run,but the CC2530ZNP still kept the default pollRate(1000ms).And if i setPollRate(10) in the znpInit() function,the pollRate could be changed succefully.

So,did i miss something?

Regards.

Hello,the setPollRate() is the function is the CC2530ZNP mini KIT example codes,

void setPollRate(unsigned int pollRate)
{
//    if ((pollRate == 0) || (pollRate > 65000))
//    {
//        znpResult = -1;
//        return;
//    }
#ifdef ZNP_INTERFACE_VERBOSE    
    printf("Setting ZCD_NV_POLL_RATE to %u\r\n", pollRate);
#endif
    znpBuf[0] = ZB_WRITE_CONFIGURATION_LEN + ZCD_NV_POLL_RATE_LEN;
    znpBuf[1] = MSB(ZB_WRITE_CONFIGURATION);
    znpBuf[2] = LSB(ZB_WRITE_CONFIGURATION);
   
    znpBuf[3] = ZCD_NV_POLL_RATE;
    znpBuf[4] = ZCD_NV_POLL_RATE_LEN;
    znpBuf[5] = LSB(pollRate);
    znpBuf[6] = MSB(pollRate);
   
    znpResult = sendMessage();

}

I found out this function only will take effect after the CC2530ZNP reset or ZSTACK restart.

And i didn't check the ZAP code,because i used ZNP firmware.I do know what is the difference between the ZAP firmware and the ZNP firmware.But in the ZNP firmware codes,i checked the MT_SYS.C and the function MT_SysOsalNVWrite(uint8 *pBuf),according the doucument CC2530ZNP interface, i could not figure out how to use this function to change the poll rate.Could you show me the way with example codes?I appreciate that.

And I already had a solution actually,i modified the MT_SYS.C, and added on my own function with cmd 0x2150,I named this function MT_SysSetPollRate(pBuf).This function would call the NLME_SetPollRate, NLME_SetQueuedPollRate,NLME_SetResponseRate to change the poll rate in run-time and take effect immediately.This is the working way i had found so far.

 void MT_SysSetPollRate(uint8 *pBuf)
{
  uint8 str[]="OK";
  uint16 val1=1000;
  uint16 val2=100;
  uint16 val3=100;
 
  /* Skip over RPC header */
  pBuf += MT_RPC_FRAME_HDR_SZ; 
  val1 = BUILD_UINT16(pBuf[0], pBuf[1]);
  val2 = BUILD_UINT16(pBuf[2], pBuf[3]);
  val3 = BUILD_UINT16(pBuf[4], pBuf[5]);
  
  NLME_SetPollRate( val1 );
  NLME_SetQueuedPollRate( val2 );
  NLME_SetResponseRate( val3 );    
  
  /* Build and send back the response */
  MT_BuildAndSendZToolResponse(((uint8)MT_RPC_CMD_SRSP | (uint8)MT_RPC_SYS_SYS), MT_SYS_SET_POLL_RATE, 2,str);
}

Regards.

Hi licheng Li

Did you get it working in CC2530 ZNP Mini. I get the following pulses in between my 4 sec transmission intervals:

I want to minimize those mini peaks to say once, between those 4 seconds, any ideas pls help!!!

Iam using CC2530 ZNP Mini

Hi, it is the CC2530 ZNP Mini which i am using,and i didn't found any problem.

What code did you use in your problem?

Hi Li,

Iam also using CC2530 ZNP Mini, running simple application code.

I had put up the same question in another forum to which I got the response to consider the the poll rate. Posting one of the posts in that query here:

I read about ZCD_NV_POLL_RATE and figured out, it is set by void setPollRate(unsigned int pollRate) function in znp_interface.c, however amazingly there is no call to that function in Simple Application - End Device code (searched manually and ctrl+F deep search). So I manually included the following lines of code in startZnp (@znp_simpleapp_utils.c) after znpReset

    setPollRate(2000);
    if (znpResult != ZNP_SUCCESS)
        return -11;/**/

which provides me this plot:

which was earlier, (before the above manual setPollRate(2000) inclusion):

While that is certainly a difference in the plot, I couldnt map the 2000mS, and more importantly, how is that 1Sec interval set by default with no call to setPollRate in original Simple Application - End Device. Atleast, if I know the root of that 1Sec interval and how it is set (since setPollRate is not called exclusively), I could further dig around.

Hey Sreekesh,

I am currently having the same problem like yours, Did you figure out How to send data at a faster rate? As i go through this thread, I see that there is a change in the data polling between the devices when you manually input the new data poll rate. Although, the rate of transmission still remains at a 4 sec interval !! But as far as I understand from this post by you; you were able to set the data polling between devices to be faster, but not the transmission rate. It would be of great help if you could give me pointers as to How you overcame this.....
