FTDI Cable to Bluetooth HC-05 Programmer

Here is a board that can program the HC-05 Bluetooth Module using AT commands.

All that is needed is a momentary reset switch and a SPST and a resistor. Didn't bother with a PCB because it would be one of a kind to program about (40) BT Modules. With the blimp project we need to rename each module to prevent confusion, Stock name is set for HC-05.

Steps to rename HC-05 Bluetooth Module
Open the Arduino IDE
Setup correct comm port that the FTDI cable is on
Select tools and open Serial Monitor
Set for 38,400 Baud
Set NL&CR


Set Switch to PROG
Push Reset Switch to place HC-05 Board to AT Command Mode
Type AT
Should reply back OK
Type AT+NAME
Should reply back HC-05
Type AT+NAME=(new name here)
Type AT+NAME
Should reply back (new name here)
Set Switch to RUN
Push Reset
