1. What is HM-10?
The HM-10 module is a Bluetooth Low Energy (BLE) device that is suitable for low power applications and has a long battery life, even when using a small coin-shaped battery. The module is built using the Texas Instruments CC2540 or CC2541 BLE System on Chip (SoC) and can be incorporated into projects to add Bluetooth functionality. It is compatible with iPhone 4s and newer models. This small 3.3v SMD module can be used for wireless communication within a range of 100 meters or less. Additionally, the module has both master and slave roles, supports data transmission, remote control, and PIO status.
2. What is the difference between HM-10 and HC-05?
Feature | HM-10 | HC-05 |
---|---|---|
Bluetooth version | 4.0 | 2.0 |
Power consumption | Low | High |
Range | Up to 100 meters | Up to 10 meters |
Security | Secure connection | No security |
Ease of use | Easy to use | More difficult to use |
Cost | Affordable | More expensive |
As you can see, the HM-10 and HC-05 have a number of differences. The HM-10 is newer, has a lower power consumption, a longer range, and a secure connection. It is also easier to use and more affordable than the HC-05. However, the HC-05 is more widely available.
Ultimately, the best Bluetooth module for you will depend on your specific needs and requirements. If you are looking for a module that is affordable, easy to use, and secure, the HM-10 is a great option. If you are looking for a module that is widely available, the HC-05 may be a better choice.
3. What is the baud rate of HM-10 at command?
By default, the HM-10 module operates at a baud rate of 9600. However, it is possible to modify the baud rate using AT commands. The maximum baud rate that can be set is 115200.
4. Which Bluetooth version does the HM-10 module support?
The HM-10 module supports Bluetooth 4.0, which is known for its low energy consumption.
5. What are some common applications for the HM-10 BLE module?
This module is commonly used in IoT projects, wearable devices, home automation, and prototyping with microcontrollers like Arduino.
