HC-05 bluetooth AT commands on MacOS

 

 I bought HC-05 to use with Arduino but ran in to some issues trying to get the AT commands working. In this example I will show how to use this with a 3.3V UART - USB cable.

Module : HC-05, ZS-040

Firmware : VERSION:4.0-20190728- BAD version

Firmware : VERSION:2.0-20100601 - GOOD version (AT commands)

MacBook <---> USB-UART cable <--> HC-05

 

 

 

1) Power on while press and holding the button to switch to AT mode

2) In MacOS use CoolTerm with these settings

3) connect the 3.3V UART to USB cable

press and hold the button every time an AT command is sent
