Hello everyone.
So here’s my setup: I have an Arduino Mega, and an Arduino Duemilanove, each connected to a SFE Bluetooth Mate module (on the Mega, it’s connected to Serial3). I’m trying to send serial data from the Duemilanove to the Mega via bluetooth, and then view what is received via the Serial Monitor connected to the Mega. The bluetooth modules are linked together, but no data seems to be passing through. Any suggestions would be greatly appreciated.
I would start by using either a MAX3232 or a FT232 IC to connect to the bluetooth Mates. Set things up so that there is a terminal emulator talking with both the bluetooth mates and make sure you can get communication between the two. The simplest way to connect two bluetooth mates is to put one of them into command mode, then connect to the other devices address using the C, command. You can perform an inquiry scan using the IS command. All this is documented in the user manual of the bluesmirf.
Next I would verify that you can send and receive data over the UART of both the Duemilanove and the Mega. Do this with either a loop back test (a.k.a local echo test) or by spitting out the same character over and over then viewing the signal on a scope.
That is how I would do it.
