Connecting your RC-300 Controller to a peripheral device via Low Energy (BLE) enables wireless command transmission. Here's how, based on the user manual: First, insert two AA batteries into the back of the RC-300 Controller. Then, press the POWER button for one second to turn it on; the blue LED will light up. The RC-300 acts as a BLE Central (Master), automatically connecting to the last device or a nearby one. Once connected, pressing any button (U/D/L/R/1/2/3/4/5/6) sends 6-byte remocon data. The blue LED blinks before connecting and stays lit when connected. Pressing a button sends 6-byte packets every 50ms; releasing all buttons sends a 6-byte packet with a value of 0. The RC-300 enters Deep Sleep Mode after 2.5 minutes of inactivity or if the battery voltage drops below 1.6V. You can also manually enter Deep Sleep Mode by pressing the POWER button for two seconds. Following these steps ensures a successful BLE connection for your RC-300 Controller.
