- Mon Mar 08, 2021 11:20 am #90751 I have an Elegoo Arduino Uno R3 board and a MakerHawk ESP8266 WiFi chip https://www.amazon.co.uk/gp/product/B07 ... UTF8&psc=1

My Arduino IDE is version 1.8.12

I have connected up the chip to my arduino as follows:

I have correctly installed the Boards Manager as outlined here: https://github.com/esp8266/Arduino and also the correct tools etc from git as outlined here: https://arduino-esp8266.readthedocs.io/ ... it-version


I want to set up my esp8266 as an access point so I opened the following sketch:
File-->Examples-->ESP8266WiFi>WiFiAccessPoint and selected Upload from my Arduino IDE.
It appears to build and upload correctly:

Sketch uses 289120 bytes (30%) of program storage space. Maximum is 958448 bytes.
Global variables use 27328 bytes (33%) of dynamic memory, leaving 54592 bytes for local variables. Maximum is 81920 bytes.

But now when I go to my laptop and view all the availabe WiFi Access Points I do not see the esp8266 access point that I expect to be now up and running.

Is there anything I am doing wrong?

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
