▓ HID Operation Mode
HID operation mode is dedicated for a user’s device to be emulated as a Bluetooth Keyboard. After
being connected, the HID report package can be transferred through the UART interface to a remote
platform, such as a PC/Laptop. In this mode, AT Commands are not allowed. Using the following
PIO table, BT-1041 can operate whole activities during the HID operation mode.
▓ HID Connection Procedures
Step1. Power On
After power on BT-1041, the paired BT-1041 is in the “Connecting mode” to continue
re-connecting the existed paired remote device. If BT-1041 is un-paired with any remote device,
BT-1041 will be in “Discoverable mode”.
Step2. Data Transfer
After connection is created, BT-1041 can accept HID report packages through the UART interface.
While BT-1041 is in “Connected mode”, BT-1041 reports the “Link Quality” message
(0x00~0xFF) every second to indicate Bluetooth connection quality. The larger value indicates the
better link quality. Value 0xD5 is a recommended value to stop sending HID report packages.
Step3. Disconnected
If the connection is interrupted (either normal or abnormal), BT-1041 will still continue
re-connecting the paired remote device.
Step4. Discoverable
When Unplug/re-pair button (PIO7) is pressed, BT-1041 will disconnect the existing connection
and/or stop any re-connecting action to be in “Discoverable mode”.
▓ HID Package Format
The packet format for data written into the UART is effectively a HID report with an additional
header. The protocol only checks that the packet matches the header and does not valid the HID
Report. It is the responsibility of the designer to make sure that the HID Reports send to the UART
match those defined in the HID Descriptor in the SDP service record.
A HID device may need to send different reports depending on whether the device is in HID Boot
Protocol or HID Report protocol. If this is needed, then additional signaling between the BC4 VM
application and the external processor may be needed - perhaps using a PIO line.

2 to n The HID Report including header.
Below is an example packet for a Boot Keyboard Report:
Note: For devices that requiring PIN entry to be made by pressing the keys on the keyboard.
Keyboard reports must be sent using the HID Keyboard Boot Report format so that the HID library
intercept these packets and extract the keycodes during pairing.
Byte Value Description

Appendix A: AT Command
The modem-like AT Command set of BT-1041 is based on Command/Response handshake. The
following sections describe syntax and commands used in command interface for the user to configure
and control BT-1041.
A.1. AT Command Format
The AT command format is:
AT<cmd><cr> or AT<cmd>=<value><cr>
*** <cmd> represents specified command; <cr> represents \r
Format Example Example
AT+<cmd><cr> AT + GLN \r Host send Get local name command
AT+<cmd>=<value><cr> AT + PIN = 12345678 \r Host send Set pin code command
A.2. AT Command Response Format
The AT command response format is:
<cr><lf><Response Code><cr><lf>
*** <cr> represents \r; <lf> represents \n
There are two categories of Response Code:
■ Category 1 Response Code:
Example Meaning Condition & Notes
\r \n 1 \r \n OK
ie, A T+INQ = 000000,15,10 \r
\r \n 2 \r \n ERROR
(1 <= maxResponses <= 10)
ie, A T+ ABC \r
\r \n 3 \r \n UNKNOWN
(command ABC is not available)
\r \n 4 \r \n FAILED
■ Category 2 Response Code:
ie, command/response successfully finished;
result to be no match
