CC1310: wmbus,send data fail

Do you use the wmbus stack (http://www.ti.com/tool/WMBUS) or something else? 

Please provide exact description on how to replicate. 

NO,My configuration is based on your reference documents

I Use the following send function

RF_runCmd(rfHandle, (RF_Op*)&radio_para.fs, RF_PriorityNormal, radio_error, RF_EventInternalError|RF_EventModulesUnlocked);
// Schedule a proprietary TX command
RF_runCmd(rfHandle, (RF_Op*)&radio_para.tx, RF_PriorityNormal, radio_error, RF_EventInternalError|RF_EventModulesUnlocked);

Meaning that you have a packetTx/ packetRX example using the T-mode patch sending/ receiving packets every 200 ms and after an hour it fails?

If that is the case, does the RX or TX side fail (are you still sending packets but stop receiving and if that is the case, which state is the receiver in) 

Does it always fail at the same point in time? 

yes.the TX side fail.after RF send data,then switch to RX,

i do not know it is the same point in time;i can catch the question point,it has no error back;
