Here is an example of what happens when I try using the WiFi from my iPhone's hotspot
I cannot get AT+CIPSTART to connect to any web server, and get DNS Fail whenever I try.
I have the same issue using a TP-Link TL-WN725N in access point mode. To clarify, I can get the ESP8266 to connect to both of these using AT+CWJAP, the problem lies with the CIPSTART command.
Whereas when I use the WiFi from my home router the connection succeeds.
I need to be able to use the ESP8266 away from home, does anyone have any advice on how to use a hotspot connection?
