how to control wemos r1d2 (esp8266 contained itself)

Development Tools IDE 1.x
1

hello i'm one of beginner
it's so hard to study arduino alone haha

my board : wemos d1r2(the board contains esp8266 already)
esp8266 firmware installed. firmware file name is : v0.9.2.2 AT Firmware.
I can't find any tool to include the file in this post :frowning:

the PROBLEM IS my board dosent' respond to AT Command.
I've installed firmware and every settings described in this link : http://www.makewith.co/page/project/1004/story/2480/
(not in English, but you can see what I've did with pictures. do not care about the code in this link, cause it worked well).

the reason why i want to use AT command is most of examples spread in internet use AT commands... I have to improve those example code for my project. I've already searched on google to find how to install esp8266 firmware but there wasn't any satisfying answer. (anyway i installed firmware after reading the post describing how to install that firmware using Arduino Uno). I saw one post similar to my problem(how to install firmware on wemos) but even the answer was it's unnecessary to install firmware because user can write code without using AT command -_-;;;

dose anyone knows how to solve this problem???
thank you to read this topic!!!

I am no expert, but what I know, you can use AT commands over serial from other MCU to slave ESP with sdk firmware. The firmware converts AT commands to ESP 'commands'.

If you are writing a sketch for the ESP, you use libraries for WiFi communication.

If you uploaded that sketch your replaced the firmware for AT-commands. That's why those AT-command do not work anymore untill your reflash the AT-firmware.

You have not told us about your project, so I am not sure if using the AT-commands would be the best thing for you.

and how will he use the AT commands? from Serial monitor? He has no other processor on the board.

I have no idea how he will use it. He hasn't told us anything about his project.
