HM-10 Bluetooth Module-China Make
The HM-10 module is a small Bluetooth 4.0 module that utilizes the Texas Instruments CC2540 or CC2541 BLE System SoC (System on Chip). It operates on 3.3v SMD and can be controlled through the serial UART connection by sending AT commands. The main purpose of the HM-10 module is for wireless data communication, but it is crucial to note that it can only connect with Bluetooth 4.0 based modules, and not with Bluetooth 2/2.1 modules like HC-05 and HC-06.
Due to its standard UART serial connection, the HM-10 bluetooth module is widely used with the Arduino and is available in two versions: HM-10C and HM-10S. The HM-10S is primarily for data transmission, whereas the HM-10C serves as a remote control version with PIO status. The HM Bluetooth modules use CSR or TI CC254x or Cypress chips, allowing them to operate as both master and slave roles.

1.How do I connect my HM-10 Bluetooth module?
- To connect your HM-10 Bluetooth module, you will need to follow these general steps:
- Power on the HM-10 module by supplying it with 3.3V power.
- Check the LED on the HM-10. If it's blinking slowly, then the module is in AT mode. If it's blinking fast, then it's in data mode. If it's not blinking at all, then there's no power or the module is damaged.
- Make sure that your device (e.g. smartphone, computer, etc.) has Bluetooth turned on and is discoverable.
- Use a serial terminal program, such as PuTTY or Arduino IDE, to communicate with the HM-10 module via a USB-to-serial converter or a microcontroller.
- Send the AT commands to the HM-10 module to configure it. For example, to set the name of the HM-10 to "MyModule", send the command "AT+NAME=MyModule".
- Set the module to slave mode by sending the command "AT+ROLE0" to enable it to be discoverable by other Bluetooth devices.
- Pair your device with the HM-10 by searching for nearby devices on your device's Bluetooth settings and selecting the HM-10.
- Once the devices are paired, you can send and receive data between them using the appropriate protocol
2.What is the PIN code for HM-10?
- The default PIN code for the HM-10 Bluetooth module is "0000" (four zeros). However, it's important to note that you can change the PIN code to a different value using the AT command "AT+PINxxxx" where "xxxx" is the new four-digit PIN code you want to use. It's recommended to change the default PIN code to a unique value for security reasons.
3.What voltage for HM-10 Bluetooth?
- The HM-10 Bluetooth module is designed to operate with a supply voltage of 3.3V. Applying a voltage higher than this can damage the module. It's important to use a voltage regulator or a voltage level shifter if you are connecting the HM-10 to a device that operates at a higher voltage level, such as 5V, to ensure the module is not damaged.
4. What is the primary function of the HM-10 Bluetooth Module?
- The primary function of the HM-10 Bluetooth Module is to enable wireless data communication using Bluetooth 4.0 Low Energy (BLE) technology. It allows devices to communicate over short distances with low power consumption
5. How do I interface the HM-10 Bluetooth Module with a microcontroller?
- The HM-10 Bluetooth Module uses UART (Universal Asynchronous Receiver/Transmitter) for communication. You can connect the module’s TX and RX pins to the corresponding RX and TX pins of your microcontroller. Additionally, you need to connect the VCC and GND pins to power the module
