Other Parts Discussed in Thread: CC3100, ENERGIA, CC3200
I configured the cc3100 wifi and added my android wifi hotspot details into it.
Then uploaded the simplewebserverWifi example on energia, pressed the restart button but only line comes is Attempting to connect to Network named: abhi.matlotia .
I think the code isn't working after Serial.print("Attempting to connect to Network named: "); this line.
Even if its not connecting to my wifi it should show not connected in serial port right?
