Modifying the Bluetooth Module Settings

Post by Jed Hodson » Fri Jul 03, 2015 9:56 am

Hi,
I have recently purchased the Freetronics Bluetooth Shield and I am trying to reprogram the HC-05 module. Could someone please tell me how to do this? I have tried shorting the key pin and managed to get the Status light flashing at 2 second intervals, but I don't know how to send commands to it. I have tried to follow this guide http://www.instructables.com/id/Modify- ... s-Using-A/ with no success.

Thanks in Advanced,
Jed Hodson

Give the following a try:

and don't forget to change the jumpers on the BT shield to 10 and 11 for RX and TX respectively.
