  • After reading and re-reading, and checking all connections before powering on, i get no communication back from the unit, other than garbage returned after i send a command. followed instructions to make sure it was set for 9600 baud, but never was able to get good communication to the module, even when no UNO-R3 is connected, 5v power and ground is connected to 3amp 5vdc regulated power supply and connected using a FTDI USB cable and a long 2 pins to go directly to pins 2 and 3.

    Running the pass-through sketch, it shows this…

    Starting SM5100B Communication…      ÿ˜’ðÿÿÿ

    The characters are never the some or in the same order and periodically change. Anyone know what i’m doing wrong???

No public wish lists :(
