HC-05 Bluetooth - JMoon Technologies Wiki Overview The HC-05 Bluetooth Module [Product link] can be used in a Master or Slave configuration, making it a great solution for wireless communication.You can use it simply for a serial port replacement to establish connection between MCU and GPS, PC to your embedded project, etc. Features Protocol: Bluetooth Specification v2.0+EDRFrequency: 2.4GHz ISM bandModulation: GFSKEmission power: ≤4dBm, Class 2Sensitivity: ≤-84dBm at 0.1% BERSpeed: Asynchronous: 2.1Mbps(Max) / 160 kbps, Synchronous: 1Mbps/1MbpsSecurity: Authentication and encryptionProfiles: Bluetooth serial portPower supply: +3.3VDC 50mAWorking temperature: -20 ~ +75 Centigrade Description The HC-05 Bluetooth Module has 6 pins- Vcc, GND, TX, RX, Key, and LED. The major difference between Master and Slave modes is that, in Slave mode the Bluetooth module cannot initiate a connection, it can however accept incoming connections. The range for Bluetooth communication is usually 30m or less. Pin Connections Arduino Downloads 1.

We live in a world where the accumulation of knowledge is exponential over time, and where the ability to continuously learn and make sound judgments is essential to survival. The most important thing any educator can impart to a student, in any context, is the ability to teach themselves. Placing students at the center of the instructional process breaks this dependency. The purpose of this website is to provide both rationale and resources for research/discussion-based instruction to instructors everywhere. An important feature of these questions and answers is that they are configurable. Contact
