In a single core BLE SOC, whenever a BLE event occurs the BLE stack takes high priority and any application code running on the single core, is delayed while the event is processed.
So has anyone looked at the nRF53840 with the dual cores to evaluate what the impact is on the "host" core vs. the "BLE" core? In other words how impactful is BLE operation on any app code running in the 'upper' core?
