Discover nearby Bluetooth peripherals and inspect their services for information and characteristics.

• View information and signal strength for all peripherals and devices, updating in real time as you move around.

• Get battery level for your own Apple devices (signed into the same primary iCloud account) — no need to install the app on all your devices.

• See model identification broadcast by devices around you, mapping the Apple device identifier to the marketing name.

• Extract software and firmware version strings from devices broadcasting this information.

• Read any characteristic's value, even for services not well known and are custom to the device being interrogated.

• Write characteristic values back to the peripheral as string, numeric or hex (pro).

• See a history of the value of a characteristic since the session started, timestamped to when the value changed (pro).

• Log found peripherals, services, characteristics and values, and export a .log file of timestamped events for your analysis (pro).

• Shortcuts integration with actions for scanning and interrogation, enumerating services and characteristics, and reading values (pro).

This app helped me find my Apple Pencil

I misplaced my Apple Pencil. I knew it was in the house. The app’s basic functionality showed a signal strength for each device some of which were named. By moving around my home and re-scanning I was able to narrow down the room and then use the signal strength from other devices to figure out the general location.

It’s not going to home in on the device or do anything magical, but it will help you figure out the general location.

The signal strength percentage isn’t calibrated very well so you need to compare percentages to devices that are a known distance away and work off that.

Great app, i just bought Pro. Although im a bit confused about the write feature.
I have a device that takes a byte array for setting an led color, but im not sure how i would set that in the app. Any ideas? :/
