Is Bluetooth firmware confirmed V1.1 or later?
Read the exact installed Bluetooth-firmware version from the documented BTR17 Bluetooth firmware information, not the separate XMOS/USB firmware version. Continue only when this Bluetooth version is positively V1.1 or later. No/unknown must stop; do not start an update here.
Look for: Explicit informed acceptance is required before the next action.
