Bluetooth: controller: Fix to use CPR preferred periodicity value (58f50cc9) · Commits · Wenxi XU / zephyr

Fixed implementation to use Connection Parameter Request Procedure Preferred Periodicity value in calculating the new connection interval used by the master role in Connection Update Indication. Fixes LL.TS.5.0.2 conformance tests: LL/CON/MAS/BV-32-C [Accepting Connection Parameter Request - Preferred_Periodicity] LL/CON/MAS/BV-33-C [Accepting Connection Parameter Request - Preferred_Periodicity and preferred anchor points] Signed-off-by:
