What is difference between HC-05 and HC-06 Bluetooth module?
The HC-05 can be a master or slave. The HC-06 is a slave only. This means the HC-05 can initiate a connection to another device and the HC-06 can only accept a connection from another device.
What is HC-06 Bluetooth module?
The HC-06 bluetooth module is a slave bluetooth module designed for wireless serial communication. It is a slave module meaning that it can receive serial data when serial data is sent out from a master bluetooth device(device able to send serial data through the air: smart phones, PC).
What is difference between HC-05 and HM 10?
Difference between HM10 and other Bluetooth Module The major difference HM10 possess is the Bluetooth Version. The HM10 is Bluetooth 4.0 module, so it comes with all Bluetooth Version 4.0 features such as speed, throughput and range. The HM10 offers a data rate of up to 24 Mbps with low-energy/low-power consumption.
How do I connect to my HC-06?
The first thing to do is to power on the Bluetooth module and see if you can connect to it. For this you need an Android device. With the Bluetooth module powered and the LED(s) blinking, on the Android device go to Settings => Connections => Bluetooth and scan for Bluetooth devices. Here the phone has found the HC-06.
How do I connect to HC-06?
Can HC-06 send data?
HC-06 works on serial communication. The Android app is designed to send serial data to the Arduino Bluetooth module when a button is pressed on the app. You can open the serial monitor and watch the received data while connecting.
How do you program a HM-10 module?
Just connect as following:
- Connect 3.3V of Arduino to the VCC of HM-10.
- Connect GND of Arduino to the GND of HM-10.
- Connect D8 of Arduino to RX of HM-10.
- Connect D7 of Arduino to TX of HM-10.
- Connect D2 of Arduino to the long leg of LED along with a 220 ohm resistor.
- Connect the short leg of LED with the GND of Arduino.
How do you pair HM-10?
BLE Scanner Android App
- Once the installation is completed, open the App and enable Location and Bluetooth permission.
- Scan for the bluetooth devices. The name of HM-10 BLE 4.0 is MLT-BT05. The default pairing code for MLT-BT05 is 123456789. So once connected, you are ready to go now.
How many pins does the HC 06 Bluetooth module have?
HC-06 uses frequency hopping spread spectrum technique ( FHSS) to avoid interference with other devices and to have full duplex transmission. The device works on the frequency range from 2.402 GHz to 2.480GHz. HC-06 module has six pins as shown in the pinout.
Is the HC 06 Bluetooth module a slave device?
The module works on Bluetooth 2.0 communication protocol and it can only act as a slave device. This is cheapest method for wireless data transmission and more flexible compared to other methods and it even can transmit files at speed up to 2.1Mb/s.
How does a Bluetooth module talk to a serial monitor?
Anything it receives from the module it displays in the serial monitor main window. Hardware serial is used to talk to the host computer/Arduino serial monitor and AltSoftSerial is used to talk to the Bluetooth module. The sketch can be used to talk to any module that uses serial communication.
How does the Arduino communicate with the Bluetooth module?
The Arduino will act as a middleman between the Bluetooth module and your computer. It will communicate with your PC over the built in serial connection through the USB cable, and with the HC-06 Bluetooth module over pins 4 and 2, using the Software Serial library.
