when wrpc is master with the following parameters:

wrc# ptp
running; e2e master
prio1 = 128
prio2 = 128
domain = 0
clock class = 193
clock accuracy = 32
clock allan variance = 50973
time source = 160

If command ptp accuracy 31 is executed a WRS stays in UNCALIBRAT/IDLE state. The change of other clock parameters (class, allan tsource causes the same effect. May be a false positive bug.
