Can I use Mod-BT BGB203 with Olimexino-32U4

[ggartec]

Hi,
I'm new user and I'll know if I can use Module BGB203 with my Olmexino-32U4 ?
I downloaded OLIMEXINO-328 and MOD-BT project for Arduino IDE and I can't find BT_Init in the receive prog.
An help is more apreciate. Thanks.

Hello Georges,

Yes, you can. They are hardware level compatible. We haven't provided an example though.

Consider that OLIMEXINO-32U4 and MOD-BT work on hardware level but the example that is available for 328 is not compatible out-of-the-box with the 32U4 board. The problem is the UART lines are not enough (since the 32U4 has no FTDI chip it handles the USB communication which restrains UART communications). The way it should be done is to upload the suitable program and then power the 32U4 from another source and disconnect the USB and then do the MOD-BT testing. If the USB is plugged it will block the possible communication between OLIMEXINO-32U4 and MOD-BT.

Best regards,
