Tag stops polling

Using both Release 1.1 and Release 2.0, I find that the PDOA Tag stops polling at 4 minutes. It happens consistently and precisely at 4 minutes. On the debugger, it seems it stops waiting for an interrupt.

What is the reason for this and how do I prevent this happening?


Can you explain more about your system?
Note: I think it is the Initiator that start the poll.
I would start with attaching a USB cable to the Initiator and monitor the serial log to see what is happing.

I set up the Node & Tag, join the Tag to the node.
Power them both down and power them up again. The Tag & Node begin ranging correctly as normal.
After 4 minutes the Tag stops polling.
