I have done every mode of instruction available annd still cant connect to the wifi module.the blue light us blinking slowly and then it is blinking fast but not connecting to wifi and caution is shown again .i have pasted the image
Hi, goes to wifi setting in your smartphone and select bandwidth 2.5 Ghz then your wifi module will connect easily
Since I also faced the same problem I connected it through mobile data via hotspot. This can be done by click “Add Network/SETUP VIA HOTSPOT” that is displayed when it asks for the internet connection. Then enter your appropriate name and password of the hotspot.
Are you still facing problem while setting up?
