Share My Creation MQTT ,ESP8266 and Internet of Things

Hi,All!
I wrote a small application on the basis of the library
https://www.b4x.com/android/forum/threads/jg-mqtt-library.51842/#post-325524
It is made in the ESP8266 chip.

The application can:
-Transfer temperature DS18b20 chip -40 + 120C
-On/Off relay 220V/5A
-Read Sensor Alarm
-Send and Read Message and Command of topic MQTT
-Timer work relay
-broker MQTT iot.eclipse.org

I can receive data and control the relay via the Internet on my smartphone 2G/3G,WIFI.
(no real IP)

Hi Alexhi,

Glad to see that my Mqtt lib is useful

Thanks to your help I have discovered ESP8266 stuff ...and I like it !

After testing (successfully) nodeMCU with lua, I have now jumped to th excellent Arduino firmware.

Hi,JP !
I also tried Arduino firmware for ESP, but it's much better. IMHO
https://github.com/anakod/Sming

• Fast & user friendly development
• Work with GPIO in Arduino style
• High effective in perfomance and memory usage (this is native firmware!)
• Compatible with standard Arduino libraries - use any popular hardware in few lines of code
• OTA (cloud) firmware updating !!!!!!!!!!!!!!!!!
• Build-in file system: spiffs !!!!!!!!!!!!!!!!!!!!!
• Build-in powerfull network and wireless modules
• Build-in great JSON library: ArduinoJson !!!!!!!!!!!!!!!!!!
• MQTT protocol based on libemqtt
• Open source LWIP stack
• Simple and powerfull hardware API wrappers
• Based on Espressif SDK v1.0.1b1

Now I use this modul ESP-12E

[freedom2000]

yes for the module I have the same

OTA --> impressive (i will try it)

Do you have HSpi example working with Sming ?

 

[alexhi]

Sming have SPI Class,but I don't use it.

Thanks

Oups...I don't have powershell for windows install...

@alex,

Thanks for sharing this information and I have a couple of questions:

1- Is there any English documentation for the module below? all hits from Google returned information in Russian language.

2- Is the small communication module with embedded antenna, is it a Bluetooth module or WiFi chip?

Thanks again

Edit:
How can I buy it?

 

[freedom2000]

The small module looks like the ESP8266 version 1.
So it should be a wifi one.

Hi! , I too not have powershell. I do it's https://github.com/anakod/Sming/wiki/Windows---Manual-Installation

Why don't use that, it integrates directly on most recent Arduino software via board management. Very best way to do.

This is the one that I use. And, you are right it's simple and effeicient (but no OTA for the moment)

Hi Alexhi,

Love this project, I have been playing with ESP for quite a long time, just getting myself back in to B4a, any chance of a copy of the
B4A project code. Will allow me to learn and create my own MQTT application.

Brilliant work, well done buddy. PS: What version of B4A did you use?

Regards
