You need to use NodeMCUs with CORRECT firmware (OS). This kind of NodeMCU can be purchased from pcstore.com.tw/aiot/ or from ChunHua Publisher.

ESPlorer IDE can take the only certain firmware with Lua or Python. If you flash Arduino code in your NodeMCU, ESPlorer can not connect to your NodeMCU.

How can I fixed this problem I already press the reset button, at first I used the arduino to do my NodeMCU program how can i clean my arduino program in my NodeMCU
You can create a Snap! cloud account in snap.berkeley.edu. For Snap!4NodeMCU, you need to purchase an IoT kit to enable a cloud account.

I think You may forget to upload "script2.lua" to NodeMCU.

Try Snap4IoT: iot.ttu.edu.tw/Snap4NodeMCU/Snap4NodeMCU.html Note that off-the-shelf NodeMCU may not work due to the lack of CoAP library. The tool works for the IoT Kit from iot.ttu.edu.tw.
