Bluetooth 4.0 BLE - HM-10
Bluetooth v4.0 module. It works with voltage from 3.3 V to 5 V, it communicates over a serial UART interface (RX, TX pins), it supports the AT command. Maximum transmitter power is +6 dBm, the receiver sensitivity is -23 dBm. It has a built-in voltage converter so it can work in the standard of 3.3 V and 5 V.

Description
A simple system of communication based on the Bluetooth HM-10 v4.0 BLE module. Communication is via the serial UART using AT command. It has a built-in voltage converter so it can work in the standard 3.3 V and 5 V.
The module has a built-in converter of 3.3 V/5V so the built-in goldpins can communicate with voltage of 5 V. |
Specification
- Supply voltage: from 3.3 V to 5 V, connected to VCC pin
- Current consumption: up to approx. 20 mA
- Transmitting power: max. + 6 dBm
- Range: up to 10 m
- The password for pairing: 000000
- Standard: Bluetooth 4.0 BLE
- Communication: UART (RX, TX)
- Pitch of pins: approx. 1.5 mm
- Small size: 40 x 15 mm
Connection
To start the module, you must connect the supply voltage to a pin marked VCC. The module is detected via the computer as unknown system or HMSoft to pair both devices, you need to enter the password:000000. In the system displayed will be a virtual COM port, through which, using any terminal, it is possible to transmit data. The board has pins of the serial interface UART - pins TX and RX that you can connect, for example, withArduinoor with a PC viaUART converter.

Communication can be tested by the pairing the module with the computer and connecting the board using the FTDI converter. In two terminal windows, you should select the appropriate communication ports and also specify the transmission rate of 9600 bps. If the configuration is correct, the text sent from one terminal will appear on the second.
The configuration of the module is via the popular AT commands to enter this mode, you need to connect the VCC pin to 3.3 V. Examples of the commands are:
Examples of the commands
- AT: - connection testing, in return we get "OK".
- AT+VERS?: - it shows the software version.
The instruction needs to be sent without a sign of line ending. More commands can be found in the documentation.
