Hi, had my Esquilo Air for a while now and only just found some time to play. Working on a Win 10 desktop had all sorts of wifi network problems that appear to have just been down to the SparkFun Weather Shield blocking the wifi module and reducing the signal strength to -78dBm or so and that appeared enough of an attenuation to drop the network. Moved closer to the wifi router and 52dBm and then solid.
While on the Win10 machine I too had the mysterious deletion of the complete SD card but also individual files when double clicked on. Not noticed it since moved it to a winXP laptop. Had previously updated to the 0.3Beta1 update.
Also noted that the network LED has a mind of its own. It comes on sometimes with the network up and sometimes it doesn't.
The Weather Shield fails with IC2 write errors when tried with the Weather Shield + Esquilo + Demo code but works perfectly with the same Weather Shield + Arduino + code from Sparkfun demo. Checked that the I2C & GPIO libs are checked. Anything I can check? More of a soldering iron type so the Esquilo was a bit of a step up for me
