Dialog Smartbond Bluetooth Low Energy – Hardware (device & reference designs)

We'd like to evaluate the DA14581 for use with our BTstack Bluetooth stack via HCI H4 (see https://bluekitchen-gmbh.com).

In the HCI Software Release for the DA14581, I found a Keil project and 2 precompiled binaries.
Since Keil Toolchain is expensive and we don't plan on developing software on the DA14581, I'd like to know if it is possible to use the DA14581 without a commercial license for Keil compiler.

What are is the configuration of the two provided firmware images and how can be be flashed?
- hci_581_active_uart.hex
- hci_581_ext_sleep_uart

Finally, in the provided patch for bluez, dialog_download_hci_firmware() in hciattach_dialog.c loads ""hci-firmware.bin". Where is this file?

Best regards,
Matthias
