MotionBoard and bluetooth

Post by enzo_87 » Sat Sep 15, 2012 12:01 pm

I want to connect a sparkfun bluesmirf module to the flex motion board to use it like a rs232. The bluetooth module has 6 pin ( PWR, GND, TX-O, RX-I, CTS-i,RTS-O), I tried to connect the first 4 on the UART slot of the motion board but I can not communicate with the card. How can i fix this problem?
Thank you in advance and sorry for my english!

some random ideas...
- check the power voltage and give the right one (3.3 or 5v?) to the board (maybe it is not in the UART connector
- check if the module wants 5V signals or the serial line signals
- you probably need to connect CTS and RTS? check their connections in the rs232 module...
- are you starting from a working example that sends on the FLEX serial line? (maybe good to check it with an oscilloscope)
