BlePad vs Sidrion Pointer

BlePad turns your iPhone into a wireless remote controller for BLE UART devices — perfect for micro:bit, ESP32, and any Nordic UART Service (NUS) compatible hardware. Great for electronics projects, education, and robotics. ■ Four built-in remote screens Game Controller D-pad (up/down/left/right) and A/B buttons with full multi-touch support. Numpad Digits 0–9 plus arithmetic keys (+, −, ×, ÷). QWERTY Keyboard Full alphabetic layout, optimized for landscape orientation. Custom Remote Freely arrange widgets on a 12-column × 8-row grid in landscape mode. Choose from Buttons, ON/OFF Switches, and Sliders (horizontal or vertical). Set custom labels, command values, colors, and sizes for each widget. Long-press repeat sends the button command every 100 ms. Pro unlocks up to 20 saved layouts, and layout names can be up to 20 characters. ■ Share your layouts Share the custom remote layouts you've created with other phones. Export a layout as a JSON file and send it however you like — AirDrop, email, cloud storage, and more. Import a layout someone shared with you to start using the same setup right away. Exporting is available in the free version; importing requires Pro. ■ Receive Log Displays incoming BLE UART notifications in real time as a timestamped text log (up to 100 entries). ■ Free vs Pro Free (ad-supported) • Game Controller, Numpad, Keyboard: full access • Custom Remote: create, use, edit, and export 1 layout • Receive Log: full access Pro (one-time purchase) • Everything in Free • Custom Remote: up to 20 layouts, plus layout import • Ad-free ■ Technical specs • Protocol: Nordic UART Service (NUS) • Write / Write without response, max 20 bytes per packet (auto-detected from characteristic properties) • Command format: +ID\n on press, −ID\n on release • Requires iOS 17.0 or later ■ Compatible devices • BBC micro:bit (V1 / V2) • ESP32 (requires NUS-compatible BLE UART firmware) • Any Nordic UART Service (NUS) compatible BLE device Note: BLE stability depends on your environment. For robotics or safety-critical use, we recommend implementing emergency stop logic on the device side.

Use your iPhone as a wireless mouse, touchpad and keyboard over your local Wi-Fi network. Move the pointer, click, scroll and type while browsing from the sofa, giving a presentation or working at your desk. MOUSE AND KEYBOARD CONTROLS Choose Mouse mode for a large touchpad, or Hybrid mode to keep touchpad and keyboard controls on the same screen. Type using your iPhone's keyboard and use shortcuts such as copy, paste, undo and Alt+Tab.
