Thanks for your response!
Is there anything particularly different about the HC-05 module that differentiates it from other bluetooth modules for Arduino?
I’m working with a xadow rephone, which has Bluetooth built in (here are details if they are pertinent: http://www.seeedstudio.com/wiki/Xadow_GSM%2BBLE).
The rephone uses the LinkitOne bluetooth library and as mentioned, I can connect to the muse headset using the xadow rephone. I just don’t get any information back when I send it any of the serial commands. That’s the part I need to fix - why I’m not getting any response from the headset to serial commands.
I also asked about whether it’s possible to use a bluetooth spp app on an android phone to test the serial commands - I thought doing that would allow me to eliminate potential problems with my code, and just test what I’m getting back from the headset. But although I can use them to connect to the headset, and send ASCII commands, I don’t get anything back.
Are there any pieces of example code using the HC-05 bluetooth module and an arduino to connect to the muse? I’ve checked out the muse sharp project and AtlantsEmbedded but didn’t see anything that I was obviously missing between “connect to the headset” and “start sending it serial commands”.
