3. Set up a pair of master and slave HC-05

The tool can help set up a pair of master and slave. It can be done by using one serial port or two serial ports. You need to plug and remove the master module and slave module multiple times during the set up process if you choose to set up with one serial port.

You are prompted to enter the name of the two modules, baud rate, stop bit and parity bit for setting the pair. Follow the instructions on the display to set up the pair. Presets can also be used in the mode.

About HC-05 AT Mode

• AT+VERSION
• AT+ADDR
• AT+NAME
• AT+ROLE
• AT+PSWD
• AT+UART
• AT+CMODE
• AT+BIND

Change Log

For the complete changelog, please refer to CHANGELOG.md.

Version 0.1.1 - 2020-03-29

Better Preset management

Added

• If preset is changed during HC-05 set up process, it first ask if you want to save changes to the preset.

Fixed

• Fix Infinite loop when attempting to retrieve the name of HC-05 module with firmware version 2.x.
• Add notification about decoding error instead of fatal error. This error usually happen when the connection between the HC-05 module and computer is unstable.

Dependencies

The tool is built on top of pyserial.
