CC2530 - TIMAC - End Device Stops responding when Coordinator moves out of range

Other Parts Discussed in Thread: CC2530

Hi,

I am using the TI-MAC version 1.3.1 based CC2530 sample application. The Coordinator and the end node are working in beaconless mode. I have observed that at times, when the end node is moved out of the range of the coordinator, the device stops working. It appears that there is no confirmation received from the MAC for data transmission. Is it possible that the maximum no of re-tries is somehow not working. Further, can some one please direct me to the correct location for max retries field and how to access it. If I set the option to MAC_TXOPTION_NO_RETRANS, the application does not seem to hang, but in this case, I always get success in the pData->dataCnf.hdr.status returned for MAC_MCPS_DATA_CNF and therefore, the application cannot use it.

Is there some known issue or other information available about this?

Are there any work arounds for this?

I plan to use the Watch dog timer, but there seems to be little information available on the WDT. Can someone please direct me to the correct documents / code!

 

Cheers

Anadi
