# Test description:
|
|
#
|
|
# This test covers the situation where the data poll interval is set to a value larger than child's timeout interval.
|
|
# The test verifies that the sleepy child would send a data poll within its timeout interval (ensuring hat child stays
|
|
# in parent's child table).
