② one USB to TTL module ③ 4 DuPont lines II. Wiring Note: The VCC of the Bluetooth module can only be connected to 5V, not 3.3V! III. Test Press and hold the button on the HC05 Bluetooth module to power on the Bluetooth module. The LED on the Bluetooth module enters the slow ...
The STATE pin on the breakout boards connects to pin 25 and pin 32 on the small Bluetooth module. On the FC-114 pin 32 in a normal IO pin and pin 25 is MCU_INT. On the boards I received pin 25 was not connected to the breakout board and so the STATE pin was not connected. Aft...
Before we start with the first example, controlling an Arduino using a smartphone, let’s take a closer look at the HC-05 Bluetooth module. Comparing it to the HC-06 module, which can only be set as a Slave, the HC-05 can be set as Master as well which enables making a communicatio...
You will see that the TX on the HC-05 is in parallel with the TX (Pin 9) on the ATMEGA16U (Via a 1K resistor.) This is the reason why with my sggested method that I suggest removing the ATMEGA328 . (And why the apparent strange way of connecting TX to TX is reqired, This ...

1, the core module uses HC-05 from the module, the output interface includes VCC,GND,TXD,RXD,KEY pin, connection status pin (STATE), the output is low if not connected, the output is high after connected 2. Led indicates the connection status. Quick blinking means no connection; slow bl...
HC-05 (ZS-040) Bluetooth Module quantity Add to cart SKU: RAD-6 Categories: Arduino, Teensy & IOT, Communications & Interfacing Tag: Bluetooth Description Description The HC-05 (ZS-040) is a serial to Bluetooth bridge module that allows for wireless communications between two microcontrollers ...
For more on AT commands seeArduino with HC-05 (ZS-040) Bluetooth module – AT MODE Most HC-06 modules do not have the button switch (the space is empty) and bringing pin 34 HIGH on the HC-06 does not do anything. STATE Pin
1. It is HC-05. 2. Use the CSR mainstream bluetooth chip, bluetooth V2.0 protocol standards. 3. Module working voltage 3.3 V. 4. Potter default rate of 9600, the user can be set up. 5. The core module size : 28 mm x 15 mm x 2.35 mm. ...
If only the board, No any "Bluetooth Function" HC-06 This's HC-06 Bluetooth module. Allows your device to both send or receive the TTL data via Bluetooth technology without connecting a serial cable to your computer. Feature: Works with any USB Bluetooth adapters. Default Baud Rate: ...
