Hi there,
So, OK I see what your looking for, but two things, The heatsinks? you WILL need them, Second is the SD card installed ?, 32Gig class A that bit me hard in this thread which you should have already read. 
Did you try to put your WIFI credentials in, to join your own wifi network SSID, password You may have an older firmware, I’m suspecting that 
try that and see if the serial output changes.

you may just need to rebuild it from the examples in arduino, try the latest BSP and Flash it, see if it responds. I use the WPS code works every time, easy piece of code to blend into any wifi scenario, I have demo’s of that and video on here. ( I can press the wps button from the browser window).
