I'm having a bit of a problem getting this wifi device to work.
The device is 3.3 uart and with it I got a USB to uart (3.3) which I've got the wifi working great. So I know the device works.
Now the nano I have v3.0 and is 5v TTL so I purchased a 5v to 3.3v little convertor with built in regulator. Now even if I just plug in the power (3.3v and gnd) it does power up the wifi but it fails to connect (red led does not turn off)
So I then tried the 3.3v on the nano but still the same output. I've tested the voltage on both the nano and the regulator and they are both 3.30v. However the voltage out of the usb to uart is 3.63v.. Do you think this slightly extra voltage is why it works via the usb or am i missing something ? I've even tried putting 2 3.3v wires to the wifi incase it was being under powered (3.3 from nano / 3.3 from TTL convertor) but it's still not working
Now, here is the thing. This module will work with Arduino. I got one for my self and personally I find so independent that there is no shield equaling this module. I mean, it's just as simple then saying ATA to a modem when you get the RING indicator and you want it to answer. It's got it's own web server page build in to configure the module, or you can configure it in Telnet mode Or using AT command when it's hooked to the serial port. Basically, this module ROCK!!!
Now your problem is the energy feeding. In the documentation that come with it, they say NOT TO USE YOUR ARDUINO FOR POWER SOURCE, or you could literally burn your Arduino period. If it could literally burn a UNO with heat, imagine what it could do your Nano, being 1/3 the size. You must get a independent source of power to feed the module, cause the TLG10UA03 require 300mA to operate that the UNO give out only 50mA.
And finally the example that come with the module will hardly work with google chrome this need to be know.
