Hi Nordic Engineers!
we bought 110 nRF52840 IC's for Field tests. 10 of them marked Q1AAAA / 1716AK another 100 marked Q1AABB / 1745AC
What is difference between series ? Why AAAA works but AABB all fail ?

As @endnode says, QIAAAA is Engineering A and QIAABB is Engineering B. Unfortunately there is a small, but important change to the reference design of the QIAABB. Please see this thread: nrf52840 Q1AABB ble advertising problem.
