I have been working on QN9021 BLE SoC solution of NXP. I found few pre-compiled files under QBlue/QN9020/QBlue-1.3.9/BinFiles_B2. I am looking for documentation of these files. I am also interested in running QN9021 in controller mode. Can someone direct me in finding correct binary files for it? Is HCI provided by these binary files standard? Can i integrate it with Host protocol stack running in Linux system (via BlueZ) via HCI interface?
