First power-up NodeMCU Ai-WB2-12F-Kit, test with Ai-Thinker Combo AT Command

For my NodeMCU Ai-WB2-12F-Kit, it's pre-loaded with Ai-Thinker Combo AT Command firmware, NOT the so called General AT Command Set.

Locate the Ai-Thinker Combo AT Command Set:

Currently, Combo AT Command Set is not listed in English version of Ai-WB2 Series Module page. Switch to Chinese version. Scroll download, click to open "Ai-WB2系列模组Combo-AT_V4.18版本指令集 (Ai-WB2 series module Combo-AT_V4.18 command set)".

In this video I try it using Arduino IDE's Serial Monitor.
