RF Sentinel 2.26.0

New: I saw it

On a device's page, tap I saw it and say what it is (e.g. "pole camera on the bridge"). RF Sentinel adds it to your watchlist with its exact address and, when it has one, its Bluetooth advert pattern or WiFi probe fingerprint, so you're alerted next time even after it changes to a new random address.
Patterns that many nearby devices share are refused, since they would match them all. A learned pattern only ever counts as probable, never strong.
Rename and Add note still just label the device for you; I saw it is what makes the app watch for it.

New: live radio waterfall

Tools > Radio waterfall, with an RTL-SDR or HackRF plugged in: a live picture of the watched radio bands, one row per sweep, while detection carries on.
Tap a signal (or Tune to a frequency) to zoom in on about 2 MHz around it in real time. Radio detection pauses while zoomed in, until Back to sweep or you leave the screen. It keeps the zoom when you rotate the phone.
Receive only, signal strength only: nothing is decoded.

New: probe-rate clue

With a USB WiFi adapter, a device that probes non-stop from one fixed address backs up a fixed-camera match (the FlipDeFlock behaviour). The device page shows the rate.

Watchlist

"Name starts with" rules for device names and WiFi network names.
Search your rules, export the watchlist from its menu, and Undo right after adding or changing a rule.

Match history and screens

Match history (Menu > History) has a search box (address, label, maker, name or evidence) and chips for Today and each kind of equipment.
When a filter on the main screen shows nothing, a Show all button brings everything back.
If Android stops asking for a permission the scan needs, the app offers to open its settings page.
Settings search hides every setting that doesn't match.
One text scale, themed secondary text, Material dialogs, Undo after removals, same-size filter chips, and Locate / Watchlist buttons on the device page.

Fixes and smaller changes

Snooze silences sound and voice only; alerts still show on screen.
One device heard again no longer counts twice towards a Bluetooth spam flood alert.
Drone (Remote ID), OUI-Spy and aircraft positions off the globe or at 0,0 are dropped instead of drawn.
WiFi probe fingerprints no longer change with the frame checksum some adapters keep.
ESP32 board text with accented or other multi-byte characters split across reads now comes through intact.
Device history files saved with a byte-order mark import again.
An odd entry in a Waze reply skips only that entry.
Memory: long traces let devices that went quiet go, history export streams to the file, and several caches are now bounded.
Turning Bluetooth off stops Bluetooth scanning; network location no longer overrides GPS; the last part of a trip is no longer lost when scanning stops.

Which file?

Either file replaces the other, and your history and settings are kept. Detection only: RF Sentinel never transmits.
