Bluetooth module BTC-1

A little gadget for our sound speed controllers of the SFR-series and the sound module USM-RC-3.

With the Bluetooth module BTC-1, the modules can be controlled via Bluetooth using the Android app "SFR-1 Controller".

Using the app, all available functions (additional sounds, WAV player, lights, servos, etc.) of the module can be controlled. With the SFR it is also possible to direct the drive (throttle and steering). A parallel operation next to a standard RC transmitter is also no problem.

The range is, due to the low transmission power of smartphones and tablets, between 10 and 30 meters! The control via Bluetooth, is therefore only suitable for models that do not exceed this distance to the transmitter!

The "SFR-1 Controller" app is free and can be installed from the Google Play Store, on any Bluetooth-enabled Android device from Android version 5.1.

The app is still in the beta phase, so it may happen that the app does not run on every smartphone or tablet.

Functions of the "SFR-1 Controller" app

Throttle and steering via sensor of the Android device
Throttle and steering via touch control in the directional pad
20 freely assignable buttons
30 freely assignable buttons, if you do not want to drive via the app. Like a graphical multiswitch module
Buttons can be labeled arbitrarily
Buttons with or without memory mode
Volume adjustment
Model memory for any number of models

Important: Starting with Android 6.0, the "Location Permission" for the app must be activated for Bluetooth BLE, otherwise the Bluetooth module can not be found! Why this is so, can be read here.

The app works only with Android, but not on devices with other operating systems (Apple/iOS, Windows Mobile, etc.).
