Battery Management

1.  Remote Control sends the information for battery level using Bluetooth battery service.
2.  The level of LVD is 2.1V ±0.1V.
3. If the battery voltage has reached the LVD value, Remote Control cannot enter the pairing mode and the factory reset mode.
4. If the battery voltage is under 2.0V, Remote Control does not operate.
5. When the battery voltage is 2.2V or higher, the Remote Control operates again.

1. Device Name: RemoteG20
2. Vender ID: 0x0957
3.  Product ID: 0x0001
4.  Vendor ID Source : Blutooth SIG
5.  Hardware Version : ‘V’, ‘1’, ’.’, ‘0’

Pairing mode & Re-pairing mode

1.  If the user presses the [HOME] + [BACK] keys on the Remote Control for more than 4 secs, the Remote Control enters pairing mode.
2.  The green led stays on while pressing and holding the keys.
3.  After that, the green lead starts blinking to indicate that the Remote Control has entered pairing mode.
4.  If pairing is successfully made, the green lead stops blinking and the Remote Control starts working in Bluetooth.
5.  If pairing is not successfully made for 2mins(re-pairing) or 10mins(pairing), the green lead stop blinking and the red lead blinks 4times. The Remote Control stops pairing and goes back to the previous state.
6. If a pin or key is missing, the Remote Control sends the un-direct advertising data for 2mins or 10mins in pairing mode after disconnect.

1.  The Remote Control shall choose a very aggressive advertising interval, aimed at the best possible reconnection experience.
2.  An advertisement interval of 20ms is recommended.
3.  This interval may be downgraded after the 30s if no connection has been established.
4.  Additional Data of Un-direct advertising Data

Scan Response Data

Un-Pairing mode

• Un-pairing from the STB clears the Remote Control bonding cache.
•  Remove Device bonding cache (manual approach – Optional): Press and hold [BACK] key while inserting batteries.

Connection Parameter

• Connection Interval Time: 10ms
• Connection Slave Latency: 99 (1s)
• Connection Supervision Time Out: 4s

Reconnection

• Upon an unexpected disconnect from the STB, the Remote Control shall automatically attempt to reconnect to the STB.
• It is recommended that the Remote Control uses an aggressive advertising interval (ex. 20ms) for the first 30-60secs after being disconnected. The Remote Control may then switch to a more battery-friendly advertising interval if the connection was not re-established after 30~60secs. The Remote Control may stop attempting to connect after a 2mins interval if no user interaction (ex. Button press) has been detected.
• If the Remote Control is not connected and the user initiates the Remote Control wake-up and connection by pressing a button on the Remote Control, the Remote Control shall cache the button press event and forward it to the STB after successfully establishing a connection.
• If a button event is cached and being held until the connection is established, any further key presses may be discarded until the cached event is successfully passed to the STB.

Key codes for STB

•  In Bluetooth mode, HID Profile is used.
•  In IR Mode, NEC format is used
  • Structure of the NEC format: Custom Code – Data – Inverse data

Characteristics and Commands

•  The IR_PROG_CONTROL characteristic is used to START(0x01) and FINISH(0x00) the update process.
• The IR_KEY_ID characteristic specifies the Remote Control KEY that is currently programmed. (Android keycode: 2bytes)
•  The IR_CODE characteristic is used to send IR codes. (IR Code fragment: variable length payload)
•  The IR_SUPRESS characteristic is used to switch between IR and BLE HID modes.(list of Android keycodes: 2bytes per item)
• The IR_KEY_EVENT characteristic is used to notify about KEY_UP(0x01, Key Code: 2bytes) and KEY_DOWN(0x00, Key Code: 2bytes) events.

IR Programming Operation Sequence

•  ATV writes 0x01 to IR_PROG_CONTROL to START an IR programming session. This invalidates any previously started session.
•  For each key that ATV wants to program:
•  ATV writes the corresponding key ID to IR_KEY_ID.
• The key ID is 2 bytes. Keys are identified by Android key codes and are always written in ascending key code order.
• The remote should ignore any key codes that it does not support.
•  ATV writes the corresponding IR code to IR_CODE.
• The IR code might be split into multiple consecutive writes. Payloads shall be concatenated in the order of arrival.
• The resulting byte sequence shall be interpreted according to IR Code Format.
•  ATV writes 0x00 to IR_PROG_CONTROL to FINISH the IR programming session. A successful response guarantees that specified keys have been successfully programmed.
  Note: Not specified keys shall operate in the BLE HID mode. Specified keys shall operate in IR mode unless configured in temporary BLE HID mode.

Temporary BLD HID mode

•  IR programmed keys can be temporarily switched back to BLE HID mode by writing the IR_SUPPRESS characteristic.
•  The payload shall be interpreted as a list of 2 bytes Android key codes that identify the keys that should operate in BLE HID mode.
•  All other IR programmed keys shall operate in IR mode.
•  This configuration remains valid until another successful write to IR_SUPPRESS or a disconnection.

Key Event Notifications

• The IR_KEY_EVENT characteristic can be subscribed for notifications about KEY_DOWN and KEY_UP events.
• Notifications shall be sent only for keys in IR mode.
