Hi, I recently purchased the WiFly RN-171, but I don't think I'm connecting it up right... could someone please explain where I'm going wrong? It's using RS-232 not SPI. I've connected a RX wire to DIO_1 and a TX wire to DIO_2 (I'm using pad 2 + 3 for data according to datasheet), but it's always just flashing/alternating between red and green - as if I'm not sending any data at all. I'm quite positive it's my connections because I've tried many different ways of sending the command-mode ASCII cmd ($$$)... Here's the datasheet: http://dlnmh9ip6v2uc...ly-RN-XV-DS.pdf I'm not using a shield, just connecting straight to the module from 3.3V. Any help would be great.

Hi,
TX Wifi module's wire should be connected to DIO_0(RX) of Netduino.

Hi - why are you only referring to one of the wires? Should I not be using 2 for RX and TX?

Cause, u already connect RX Wifi wire to DIO_1 (TX) correcly.
