Hi all,
I am trying to get my Arduino UNO R3 to communicate with a bluetooth module and write characters sent over bluetooth serial to an LCD attached to the arduino.
Bluetooth module (http://www.lctech-inc.com/Hardware/Detail.aspx?id=684fb223-1a23-4b83-8dbd-4d58c2b3c0cb)
So far I have proven the Arduino and LCD using the 'SerialDisplay' example sketch by sending characters from hyperterminal through a MAX232 then to the arduino - works a treat!
I have also used hyperterminal to prove the bluetooth module. I had an android app that can send characters via bluetooth, which the module sends vi aserial through MAX232 to hyperterminal. Works great.
However, when I connect the bluetooth module directly to the Arduino and use the android app I get nothing on the LCD screen.
Any ideas why this is not working?
The bluetooth module has inputs for 5V & 3.3V, I have found that it wirks fine with hyperterminal at 5V only.
