> 3 dayTried the Link It 7688 and the Microchip RN171 The NodeMCU is the way to go. With the Arduino IDE I had a working custom AP in four hours and that includes downloading then learning to use the IDE . I loaded the built-in example code then copied and pasted from another example then a couple of tweaks followed by a one click download . The other WiFi chip makers need to realize that the IDE is just as important as the chips capabilities.

> 3 dayMy go-to board. I have about 15 of these around the house for various things. When I first discovered this board, I dabbled with micropython, but esphome is so good theres no point in using anything else. I use them for dht22 sensors, reed switch sensors, push buttons (e.g. voice control turning on a PC), controlling servos, 315Mhz transmitter for controlling fans, etc all through home assistant. Awesome boards.

> 3 dayThis thing is the best thing ever. So easy to get hooked up to WiFi and transmitting data from a Dallas one-wire sensor. Took me like 2 hours.

> 3 dayI was having problems getting serial output to work. It was just giving me garbage output. After contacting the seller, they suggested that I reflash the board and change some settings, which I did, and then serial output was fine. You can get the reflash by searching Gitbub for nodemcu-flasher. After reflash, make sure your IDE settings under the Tools menu are as follows: Board -> NodeMCU 1.0 (ESP-12E Module), Flash Size -> 4M (3M SPIFFS), CPU Frequency -> 80 Mhz, Upload Speed -> 921600. In your code and serial monitor, make sure to set them to the same speed.
