EH-MC10 Command Interface User Guide
1.Introduction
The command interface is a set of ASCII commands and indicators with which the user can send
command to the Bluetooth module via UART interface from host (PC, MCU, etc.).
The commands are used to send to Bluetooth module from host. The indicators are output from the
Bluetooth module to the host for indicating the status of the module.
In addition, there are some IO indicators available when the UART is used to transfer raw data. As
a complement of ASCII commands and indicators, the IO indicators are also a part of AT COM-
MAND.
1.1. Default Configuration
The default configuration of UART is given below:
baud rate: 2400 Data bits: 8
Stop bits: 1 Parity: None
Flow command: None
The default UUID of service is given below:
Service UUID : 11223344-5566-7788-99AA-BBCCDDEEFF00
2. Command and Indicator Syntax
2.1. General Syntax
The general syntax of AT command is shown as below:
→AT+CMD[=Para1][,Para2][, RawData] <CR><LF>
The general syntax of AT indicator is shown as below:
←IDC[=Para1]<CR><LF>
Note: For the examples in this document, the command sent to the Bluetooth module will be shown with “→” at the
beginning of the line, while the indicator output by Bluetooth module will be shown with “←” at the beginning of the
line.
2.2 Description of each field
“AT+” ： command line prefix.
“CMD” ： command. All of the commands are listed in section 5.
“IDC” ： indicator. All of the indicators are listed in section 4.
“= ” ： separator between command/indicator and parameter. It’s only needed if a
parameter is presented. Para1 is the first parameter. Not all of the commands
have a parameter.
“,” ： separator between parameters. It’s only needed if subsequent parameter is presented.
Para2 is the second parameter if available. RawData is the raw data which will be sent by the
command. Only parts of the commands have this field.
<CR><LF>： terminator of the command, hex: 0x0d 0x0a

EH-MC10 Command Interface User Guide
Notes:
1. All of the parameters are composed of ASCII characters while the RawData field can composed of any data
contents.
2. In indicators, the module prints hex values in low case. For other places in the document we always use upper case
characters for hex values.
2.3. Examples
Here is some examples show how to use the AT commands and indicators.
→AT+NM=EH-LINK<CR><LF> configure the GAP device name characteristic. The new name is
“EH-LINK”.
←OK<CR><LF> response from the module to indicate the command is adopted.
Notes: For the examples in this document, the command sent to the Bluetooth Module will be shown with “ → ” at the
beginning of the line, while the indicator output by Bluetooth Module will be shown with “ ← ” at the beginning of the
line. “ → ”and“ ← ”not send with the ascii data.
