Issues Connecting ESP8266 to iPhone Hotspot WiFi

Hello everyone!

First post here, so hi to all! Wasn't sure exactly where to post this particular query, hence posting here.

So, I have purchased two ESP8266 boards; a Wemos D1 Pro Mini and a NodeMCU - both seem to fire up well when I connect them to my Mac, though the Wemos certainly flashes much, much faster than the NodeMCU, but that's another thing. I installed the CP2012 drivers, all has gone smoothly and I can upload sketches to both boards using the Arduino IDE without issues.

Here's my problem.

I don't have home WiFi in the conventional sense, as I get all my WiFi requirement from my iPhone via a wonderful mobile package from my mobile provider. I have no need to have to pay out any more than I need to for a service provided here in the UK by Virgin or Sky or a.n.other etc, and am able to do everything I need on my Mac or iPad with them tethered to the iPhone hotspot - either by WiFi or USB cable. Speeds are great too!!! :D

I have tried to run the 'WiFiAccessPoint' sketch from the examples library, and have experienced issues when trying to connect to my hotspot. Here's a detail explanation of what I have done.

I do have a WiFi router here, and do have separate home WiFi, it just isn't connected to the internet. I use it for WiFi connected HDD storage and for my printer etc.

Once I discovered I was unable to get either ESP8266 board to connect to my iPhone hotspot, I thought I'd best test them both using my home WiFi. This worked perfectly, and I was able to open the IP address 192.168.4.1 page and see the message 'You are connected' successfully, using both ESP8266 boards. I entered the SSID and passwords for my home WiFi in the sketch code and they both connected to it without issues.

Alas, when I change the SSID and password to reflect my iPhone hotspot credentials, neither board will connect, and I don't see the 'You are connected' message when going to that IP address.

So, can someone advise me please as to if I can, and if so, how I connect an ESP8266 board to a iPhone WiFi hotspot - one that everything else connects to easily - even my AppleTV!!

Hope I've explained the issue in enough detail, and hope someone can help me.

Many thanks
John

Hotspot is probably 5Ghz, while the other one it was able to connect to is 2.4Ghz. The esp doesn't support 5Ghz connectivity.
