Openmote node stops communication after about 10 minutes of pinging it using timeslot 15ms

Description

Preconditions:

  • One openmote-cc2538 as node (15ms timeslot)

  • One openmote-cc2538 as dagrrot (15ms timeslot)

  • The two motes are synchronized

  • run openvisualizer
    Scenario:

  • ping the node continuously (infinite)

    Expected behavior:

  • The node is always reachable by ping as long as it is running

  • Both node and dagroot are connected
    Seen behaviour:

  • After about 10 minutes of continuous ping, the node (sometimes the dagrrot) hangs and become not reachable by ping. It radio LED is off

The issue is systematically reproduced
