Forum Post: RE: why the end device send the Date Request Frame crazily?

hi

   thank you very much for your help! And I found the end device can join the zigbee network?  But i do not understand why my original settings cause the end device  can't join the network?

  now i use the zb_SendDataRequest() function as follows,

zb_SendDataRequest(_NIB.nwkCoordAddress,
SENSOR_HEART_BEAT_REP_CMD_ID,
rfmemtemp.len,
(uint8*)rfmemtemp.buf,
0,
AF_TX_OPTIONS_NONE,
0 );

I have set the parameter txOptions as  AF_TX_OPTIONS_NONE, it not need requesting acknowledgement from the destination.but the ZED still receive the response form the ZC !If i want to send a packet of data in the ZED  and does not need response form the ZC  when it receive the packet of data,How can i do with the function ?

regards!
