Introduction

RC-300

The RC-300 remote allows you to control robots via Bluetooth Low Energy (BLE) communication.

Specifications

Item	Description

Communication	BLE (Master)

How to Use

1. Power On
   • The central button serves as the POWER button. Press it lightly for about 1 second, and the blue LED will turn on, indicating the power is on.
2. LED (Power and BLE Connection Status)
   • If not connected to a BLE slave device, the blue LED will blink repeatedly.
   • Once connected to a BLE slave device, the blue LED will stay on without blinking.
3. Power Off
   • Press and hold the central POWER button for approximately 2 seconds. The blue LED will blink rapidly four times before turning off.
4. Auto Power Saving Mode
   • If RC-300 is not used for 3 minutes (no button presses), it will automatically turn off to conserve battery power.
   • If the battery voltage is low and needs replacement, the LED will blink rapidly four times, indicating power-saving mode.
5. Transmitting Button Press States
   • While RC-300 is turned on, it transmits packets corresponding to the pressed U/D/L/R/1/2/3/4/5/6 buttons to the paired BLE slave device.
   • It also sends a packet indicating that no buttons are pressed when all buttons are released.
   • For packet details, refer to the Code Map.

How to Connect

Available Wireless Modules and Controllers (1:1 Pairing)

Module	RC-300
RB-100	✓
RB-86 / RB-88	✓
CM-151	✓
BT-410 Slave Module	✓
BT-410 Master Module	X
BT-210 Slave / Master Module	X
BT-100/110A	X
ZIG-100/110A	X

Connection Procedure

• Confirm that the RC-300’s blue LED is blinking.
• Check if the LED on the BLE slave device you want to connect to is blinking.
• Move the RC-300 close to the BLE slave device you want to pair with.
• Once pairing is successful, both devices will have steady, non-blinking LEDs.
• Proximity pairing like this is required only during the initial pairing; subsequent pairings will occur automatically when both devices are within range (approximately 10 meters).

Code Map

When buttons on the RC-300 remote control are pressed, the corresponding code values are transmitted as shown in the code map below.

When more than 2 buttons are pressed, the sum of all code values for the pressed buttons will be sent.

• Example Button U + Button 3 => Button U (1) + Button 3 (64) = Sent Value (65)
• Example Button 1 + Button 5 => Button 1 (16) + Button 5 (256) = Sent Value (272)

Communication Packet

RC-300 communication packets use the following format, similar to RC-100 series remote controllers.

• ~ represents Inverse (1’s Complement)
  • Example ~0xAA -> 0x55, ~0xF0 -> 0x0F
  • Example DATA : 0x1234 -> Packet : 0xFF 0x55 0x34 0xCB 0x12 0xED

How to Insert Batteries

1. Open the lid on the back of the controller.

   

2. Insert the first battery into the compartment, taking care to insert in the correct polarity.

   

3. Insert the other battery.

   

4. Press both batteries firmly to confirm insertion.
