Hi All,


My JN5168 based endpoint is not seeing the data returned from a beaconed coordinator after a Data Request. There is no ACK either.

Looking at the current being drawn by my endpoint it appears to be shutting down its receiver immediately after sending the data request. This fits in with the lack of an ack.

The coordinator is Atmel not Jennic based. bAutoRequest of the Pib is set true.

In the above screenshot of a network capture 1134 causes the coordinator to want to send data to the endpoint. Beacons get bigger as endpoint short address is appended.

1138 is the data request which the coordinator responds to at 1140. Theres no Ack because I think endpoint has shut down its receiver. This seems to be the basic problem.


Any idea what is going on? 


The structure of the code is as HomeSensorEndDevice example from the old Jennic days.


kind regards
