WizFi Enterprise w/ Arduino

Question

Hello, On my local computer on a university network (with Enterprise encryption) I am running a server in which I am trying to access using the WizFi210 w/ Arduino. I have a couple of concerns. I am using the following board: [url]WiFi Shield V2.2 for Arduino (802.11 b/g/n) -DFRobot Initially I was using an Arduino Due and I receiving an [ERROR] and I was not able to supply AT commands. I switched over to the Uno and it works just fine. Does the WizFi not like 3V3 logic? I prefer to use the Due. With the Uno, I am able to communicate with it via serial. It takes a couple of “AT” commands but it works eventually. For example: [code]at [ERROR: INVALID INPUT] at [OK] at [OK] at [OK] [/code] However I cannot use the SmartScript (1.1.1.0_W(2)). I am getting Serial Command Error (see attached). If it isn’t obvious, I am a newbie with networking and such. If there are some resources (other than the datasheet) to help me connect to the university network. I would appreciate it greatly. 786×795 52.2 KB

Hi Please refer to the following link. dfrobot.com/wiki/index.php/W … KU:TEL0047 It is a dfrobot wikipage of your WizFi210 shield. WizFi210 chip working on 3.3 voltages but the shield working on 5 voltages. Because voltage level down regulator exists in the shield. Would you test the shield via USB & serial terminal? The image you attached, “+++AT” command is incorrect. So [ERROR] message was occurred. In different way, Ignore the error about “+++AT” incorrect command, and try to follow the programer’s guide. wiznet.co.kr/product-item/wizfi210/ wiznet.co.kr/wp-content/uplo … E-docx.pdf In order to get more answers, please visit the dfrobot forum.
