If "Connect via Bluetooth" doesn't find the panel (known issue on some third-party iOS browsers, e.g. Bluefy), try "Show all devices" and pick "Autoterm PU" (or "Timberline…") from the full list — you only need to do this once. After the first successful connection this page remembers that exact device and reconnects to it automatically on future visits, no list or picker involved.
Tuning knobs for the fragment burst-transfer protocol used by all 3 upload tools below (self-update, distribution slots, raw upload). Saved in this browser.
Loads a build into the panel's dedicated restore area and reboots to apply it, in one step. The panel's own bootloader verifies and applies it. Only versions matching what's currently running are listed (same logo/language variant) — this is a single fixed-purpose area, not one of the 3 generic slots below (those can hold firmware for any other device, no restriction). Newest matching version is pre-selected; pick another to roll back or repeat a specific build instead.
For relaying to OTHER CAN devices (heaters, MBC-2, other panels…) — any type/version, no filter. Writes data, then the slot's meta record, ready for SlotsScreen's "Burn" on the panel.
Raw address+length access to the external flash (8 MB) — the same protocol CAN Tool already uses, mirrored over BLE. Diagnostic tool; not needed for normal use.
