Full Tutorial (Explanation📘+ Schematic🔌 + Source code💻)
➤www.techtonions.com/signal-es...
This tutorial shows how to send text messages (notification) or Images to your Signal app using ESP32. Now your ESP32 projects will be able to send any alerts on the Signal app.
We have used Bot🤖 named as CallMeBot to send messages to Signal app by calling bot API from ESP32.

FANTASTIC! man, I always used pushover but it seems I don't need it anymore ;-)
In 3 minutes you covered what others would take 30 minutes and millions of sponsors in between ;-)

Great to hear that you liked the project that we shared.

Hi dear, Thanks for sharing such an Awesome project.
I m getting " Error compiling for board ESP32 Dev module " error on compiling the code .
I m using Arduino IDE ver. 1.8.13 & ESP32 board 1.0.6.
Can you please share which ESP32 board should I use which is compatible with this code & what settings i should select for esp32 board so I don't get the error.
An early response will be highly appreciated.
Thanks & kind regards.

Wow 👍I love you

[@altitude1039]

OMG ☺
Thank you for this!
Worked great, and has enabled me to simplify my code. I am running out of memory.
A note to users: If you use the # symbol in your custom message, it will cause an error.
I'm new to coding, so I'm not sure why, but took me a few minutes to figure out what the error was caused by. Once I removed the # the error was gone.:)

[@TechTOnions]

Thank you Altitude for pointing out the # thing it will help others to run the project successfully.

Good video, but please use human English instead of robot voice. The worst accent in pigeon English is always better than the generated voice.

Sir even after connected to wifi successfully after pressing switch on serial monitor button count increasing message is there but with error please help me what to do

[@sowaravkumar388]

And when i am sending message from browser after copying url then receiving messages perfectly fine but not with esp32
Showing "error" after each button press help me how to resolve this issue

[@TechTOnions]

Sorry to here that you get an error. As per our code it will only print error when it do not get an HTTP response code 200.
Have you tried the first example without button that is given in our tutorial here
www.techtonions.com/signal-esp32-send-message-and-image/
Additionally, do one this inside postData() function, after this line
httpCode = http.POST(url);
Add this
Serial.println(httpCode );
This way we will get to know what kind of http error code you are getting.
Have a great day.

is it not working on ESP8266? replaced wifi. h with ESP8266wifi. h. , httpclient with ESP8266httpclient, but it show error msg on serial monitor, not sending msg.

[@Kaynatwaqas]

-1
error
on serial monitor.
