BlueNRG ACI protocol

[ELema]

Is there a document describing the bluenrg ACI protocol ? I intend to connect a windows computer to a X-NUCLEO-BNRG2A1 via UART, and use the default DTM firmware to do some basic evaluations.

I can see these possibilities:

1. reverse-engineer BlueNRG-1_2 DK 3.2.1\Library\STM32L\Middlewares\ST\STM32_BlueNRG1\SimpleBlueNRG1_HCI to find out how commands are sent
2. reverse engineer BlueNRG-1_2 DK 3.2.1\Project\BLE_Examples\DTM\src\DTM_cmd_db.c to find out how commands are received
3. port BlueNRG-1_2 DK 3.2.1\Library\STM32L\Middlewares\ST\STM32_BlueNRG1\SimpleBlueNRG1_HCI to windows

All these are time consuming, and would not be needed if there was a document describing the ACI protocol. I could not find it, but does it exist somewhere ?

Thanks !
