HP RC411 RCU Remote Control

Purpose:
The purpose of this document is to define and identify the operation manual of project HP RC4111801/01R & RC411 RCU. The HP RC4111801/01R & RC411 RCU, will be referred to in this document, as the “RCU”. This RCU is transmitting BLE / IR for Monitor control.

Out Of Box Experience

• First time inserting batteries,
• RCU works in IR mode
• RCU goes into pairing mode for 60 seconds by pressing the <<BACK + HOME>> key combo over 3 seconds.

General Product Description

Overview
This RCU is transmitting BLE / IR for Monitor control.

 Control Monitor
The RCU can be set-up to control the APEX32 Monitor in either BLE or IR mode (mutually exclusive).

 Control Monitor – BLE
The RF platform is BLE, using HOGP (HID Over GATT Profile) as the top layer. The RCU will pair with the APEX32 Monitor first before control over BLE is possible

Control Monitor – IR
The IR protocol to control the Monitor is RC6modeA. All features that rely on IR communications are disabled when RCU is in RF mode

Product Requirements

Factory Default Settings (Out-of-Box State).

1. The RCU is not paired and the BLE pairing table is empty.
2. The RCU is at IR mode, sends Monitor IR codes.

Data Retention
The RCU will retain previously stored settings in the event of a power down. Below are the data that will be stored in non-volatile memory:

1. Monitor control medium: BLE or IR.
2. BLE pairing information.

 Key Code Tables

RF Profiles and Reports
All Monitor RF key codes are transmitted through BLE HOGP profile, the control is basedon HID Consumer page (0x0C) and Keyboard page (0x07).

   • Protocol: RC6 Mode 6A,
   • Carrier Frequency: 36Khz
   • Customer ID: 0x8011H

BLE Mode5.4.1 BLE Parameters
<I>. Device Info:

•  Device Name: “HP RC4111801”
• Vendor ID: 0x005D
• Product ID: 0xF08D

Note: At any one time, the RCU can only pair with 1 Monitor. The RCU keeps connection if the

Monitor is turned on and within BLE effective distance with the RCU.

<II>. Connection Parameters:

• Connection Interval: 8 (1.25ms x 8 = 10ms)
• Slave Latency: 99
• Supervision Timeout: 4 seconds

Note: RCU will send the request of the link parameters upon link establishment. In BLE communication, the requested connection parameters will be up to the host to either accept or reject, so the actual parameters applied may differ from the requested value defined above.

Different connection parameters will impact BLE response and power consumption. OMNI recommends Monitor side to always accept and apply the above parameters for the most optimized performance for BLE response and power saving.

Connection Behaviors
Once a remote and Monitor are paired, the BLE link will be kept maintained (using the connection parameters in section 5.4.1)

If the host and remote disconnects, the following occurs: 

1. After disconnecting, the RCU continuously transmits direct advertising at low duty cycle for 5sec (no LED blink). After 5 seconds, remote goes to Step 2. This process is abort if RCU gets connected within seconds.
2. RCU enters Sleep mode until the next user keypress. The process will start again from Step 1.

Battery management

Low Voltage Detection

1. If RC V battery is ≤ 2.1V, fast blink LED for 2s to indicate battery low: Do not send RF to reconnect. Do not fire IR.
2. If RC V battery ry is > 2.3V, do normal operation (IR, BLE).
3. If RC V battery is 2.1V< V battery ≤ 2.3V, transmit IR/BLE low battery message upon user press keys:
   • Case 1: RC is unpaired, user use RC as normal IR RC (don’t pair RC with any TV). If RC V battery is 2.1V< V battery ≤ 2.3V, send battery low key (000.195) via IR key code per 10 key presses.
   • Case 2: RC is paired, paired TV is not connected. (RC was used to control another TV).

If RC
V battery is 2.1V< V battery ≤ 2.3V, send battery low key (000.195) via IR key code per 10 key presses.

• Case 3: RC is paired, paired TV is connected. If RC Vbattery is 2.1V< Vbattery ≤ 2.3V, send battery low via IR & BT HID alternatively every 10 key presses. Example:
• 10th key press sends IR battery Low keycode (000.195).
• 20th key press sends battery low (0x71) command in HID keyboard format. 30th key press sends IR battery Low keycode (000.195).
• 40th key press sends battery low (0x71) command in HID keyboard format.

LED Operations

LED Configuration

 LED Behavior  Remote Control Setups

General
The Setup features stated in this section changes the settings, activate a unique feature. Each feature is triggered by a set of unique combo keys.

All setup modes can be triggered no matter Monitor control medium is RF or IR. Before entering setup mode via combo keys entry, the RCU will check if battery voltage is at LVD status. Setup modes will not be triggered if battery is at LVD status. In such an event, the LEDs will notify the user through the LVD blink. The RCU will then return to user mode.

Pairing/Re-Pairing (IR or BLE)

• Pairing/Re-Pairing (IR or BLE)
• The RCU shall only be able to pair with one Monitor at any one time.
• The Secure Simple Pairing shall employ the “just works” for the pairing process.
• The RCU acts as a BLE slave device.
• After paired with host successfully, the pairing data will be bonded into the NVM so that the pairing won’t be lost after batteries change.

Press and hold <BACK + HOME> keys for at least 3 seconds. RCU will then enter discoverable mode:

1. RCU is only allowed to pair to maximum one host. Once the pairing combo keys takes effect, RCU will firstly terminate the present connection.
2. RCU then enters discoverable mode, sends out undirected advertising for pairing. The LED blinks during the whole discoverable state.
3. Once RCU is successfully paired with the host: the LED performs Confirmation blinking.
4. In case RCU has not gotten paired with any host after discoverable timeout, or pairing processis failed: the LED performs an error blink to indicate RCU was not paired.
5. During the discoverable period while not paired yet and before timeout, it is allowed for user to abort the discoverable state by pressing <BACK> key or <HOME> key. RCU stops pairing and remains unpaired state.

Factory Reset
<< OK + MUTE >>
Press & Hold << OK + MUTE >> simultaneously for 3 seconds. the remote control will delete all settings and returns to factory default mode as described in 3.1.(Red LED 1 on for 1000 ms). Feature Combo

 Google Bug Report
<< OK + BACK >>

1. Press <<OK+ BACK>> simultaneously for 1 second, RCU will send OK and BACK combo RFcode to Monitor.
   • if RC is not connected to TV, send IR code 000.157 as long as the keys are keep pressed.
   •  If RC is paired and connected with TV, send BLE hid consumer control code 0xEC.
2. For several seconds, Monitor will generate BUG REPORT, and send to google service (only request for android O and above).

Google Accessibility Shortcut
<< DOWN + BACK >>

1. Press <<DOWN+ BACK>> simultaneously for 1 second, RCU will send DOWN and BACK combo RF code to Monitor.
   • IF RC is not connected, the RC transmits will transmit 000.114 command (transmit only 1 RC frame code) via IR.
   • IF RC is connected, transmit 0XED via BT command (consumer Control HID 0X0C).
2. The Monitor received the code form RCU will turn on/off the Accessibility Shortcut function.

Voice Function

• RCU features a button to activate the Voice Search application to search for content by speaking through the remote’s built-in microphone.
• The RCU supports one-way voice transferred from RCU to host.
• Google Android-R GATT voice – for host that runs Android-R (ATV11 voice spec. version 1.0);

Voice over GATT for Android R
Press and released <voice> key to open the voice function, RCU will close the voice function after receiving the stop command sent by the host.

 Stuck Key Timeout
Stuck Key Timeout is a precaution taken in the event a key is being pressed continuously for 30 seconds (+/- 3 seconds). To conserve battery power, the RCU will stop all IR/RF key codes transmission automatically. It will resume operation after all keys are released.

 Battery Voltage Monitor

• LVD check will be triggered after a signal key is released in user mode.
• In BLE mode and IR mode, when the LVD is detected (battery voltage<2.3V), upon key-release when not in any set-up mode: the BATTERY LOW-LED gives a warning blink (see 3.6).
• While RCU works in BLE mode, it supports Bluetooth standard service of battery level notification.
• The paired host is then able to get battery level of the RCU. The battery level report is described as below:

OTA
The RCU supports Google Android-R+ OTA
