PING bug in WIP plugin v.3.20

How i can see after some searching on forum, PING errors has a long history. Anyway:

Module Q24PL
Q24 SDK v.3.22 (latest):

  • Firmware v.6.57g, 6.57h
  • WIP plugin v.3.20.1030

If module application use wip_ping… functions for ICMP-ping, sooner or later (from one to some tens pings) exception and reset occurs.

UPDATE: Actually module restarts without exception, just normal power_on indication.
And WIP plugin v.3.20.1040 (from current Sierra Wireless software suite) - the same problem.
