Hi Nordic
When inspecting the nRF Connect SDK information, the headlines show that BLE stack has obtained BLE qualification.
Digging a bit deeper, it turns out that this is only the case for the nRF52 SOC, that can use the SoftDevice Controller.
See: Bluetooth Qualification — Zephyr Project Documentation (nordicsemi.com)
It seems odd that Nordic Semi does not provide a qualified BLE stack for the flagship MCU nRF53.
When will Nordic Semi provide a qualified BLE stack for nRF53?
