Hey guys,
So I am working on a project that involves an Arduino reading sensors (temp, pressure, rpm) and sending the data to android tablet to MIT app inventor app. This will take it and put it to gauges. My problem lies in the usb communication. I figured out if I use a regular uno rev 3 it communicates just fine. With the Wifi rev2 I can get it to connect but then it usually just brings in the first character I sent and disconnects and if I try and reconnect it says "Connection Failed: controlTransfer failed" using Serial USB Terminal app by Kai Morich attached the github for it. I don't believe the issue is with the apps. The MIT app I built the SerialOpened tag never goes true. I am pretty sure it has to do with the different boards having different processors. Would really like to use my Wifi Rev2 as it has the accelerometer and wifi on it.
Let me know if you have any suggestions to try and get this working.
Here are some screenshots to help show the issue
This one is with the WIFI Rev2
This is with the regular Uno
and here is the data after connected top is with regular Uno and bottom is with Wifi Rev2
Thanks in Advanced
