Hi, thanks for very nice video. I followed same instructions in video, but not able to see Wemos D1 mini as Access point. Please suggest.

[@EmbeddedGate]

Is there any error in program?

[@girishpanchal9072]

@@EmbeddedGate hi, thanks for responding. There is no error while uploading the code. I have checked wifiscan code also but result is 'no network found' I checked with baudrate and com port but still issue persist.

[@juanzepedea8936]

Awesome!! Everything working as shown. How can i have more sensors reading?

[@bigshoio]

Does this code on Arduino IDE work for ESP32?
If not, do you have any exemples of getting data from ESP32 and showing on an app made with App Inventor?

[@EmbeddedGate]

Yes, this code works with esp32.

Thx for the project ,can you tell me how to display multiple sensors pls .

Many Libraries are not available and not running, what is the problem?

[@EmbeddedGate]

What is the error?

[@ramishawamreh9070]

I've updated the Libraries, but still "ESPAsyncTCP.h" not available, and other libraries in your code!

Thanks very much my dear for this nice video. Please, can you tell me how to use two sensors and get the two sensors reading in the Mit app. Please, I am waiting for your reply urgently. Thanks for your understanding and love

[@EmbeddedGate]

Hello. Thanks for the comment. It is possible to read multiple values using the MIT app inventor. I will make a video for that.

[@Charles-lt9rr]

@@EmbeddedGate My dear, thanks very much for your reply. I am waiting for the video. How I wish the video will be out this week. I need the video urgently. I am wishing you all the best!!!

[@anjalimaurya1379]

from where did you get that IP? is it the IP from program?

[@EmbeddedGate]

Base Address of nodemcu.

Sir how to send multiple values?

Already, the video is available on my channel.
