Overview

Tool boundary
- OP Manager supports Bluetooth upgrade mode only (red LEDs).
- USB physical-port upgrade is supported only by OP-ISPTOOL — see USB Upgrade Mode Guide.
- Infrared fixture mode (green LEDs) is not supported by OP Manager — use OP-ISPTOOL instead.
- Firmware packages and OP-ISPTOOL downloads: OP-BT/OP-BTS Firmware Downloads.
Get OP Manager from App Store, Google Play, or Microsoft Store. Zip install options are in the Installation Guide.

Connection method differences
- Serial (and a future desktop USB connection channel in the app shell — this is not the same as OP-ISPTOOL USB physical-port upgrade): can reuse the current connection without disconnecting and go straight to the upgrade page. OP Manager currently upgrades in Bluetooth upgrade mode only.
- BLE: disconnects the current session and opens a firmware-upgrade-only scan list; prompt: Select a device in upgrade mode and connect via Bluetooth.
