Can anybody help me in implementing rabbitmq client for ESP32(NodeMCU Lua)..?
Actually I'm having little knowledge on MQTT I've implemented basic publish and subscribe with Mosquitto broker on ESP32(NodeMCU Lua) which is already available in NodeMCU documentation.
Now I want to work with Rabbitmq but I don't know how to work with that, where to start and there's no much available resources for guiding how to use rabbitmq in NodeMCU Lua and any efforts towards this will be appreciated.
I'm having doubts like can I able to implement with the existing API's (module) provided by NodeMCU (https://nodemcu.readthedocs.io/en/dev-esp32/modules/mqtt) or need to implement a dedicated client for Rabbitmq please help me to get solution for this maze and also please provide me any sources.
Abhi - if this is still an issue for you then perhaps I can help:
you do NOT need any RabbitMQ plugins or other code on the NodeMCU device.
you DO need your NodeMCU firmware compiled to include the MQTT module.
you DO need to enable the rabbitmq_mqtt plugin on your server.
For help with NodeMCU stuff look at https://nodemcu.readthedocs.io/en/release/modules/mqtt/
And for the RabbitMQ plugin: https://www.rabbitmq.com/mqtt.html#enabling-plugin

Is there any way to implement MQTT protocol on Ingenico's POS devices? I am currently working on iCT220 on which I want to implement IOT project. In this project, I will be sending some bytes (may be 400-1000 bytes) of data to the broker (server).
There are lots of source codes for the library available in the internet, but all make use of Linux or Windows socket libraries, where as Ingenico's devices come with proprietary libraries.
Have anyone implemented similar project on the same devices? Can anyone guide me to the process of implementation?
Thanks in advance,
Pankaj
Surely, you will need to build it from source.
I had a look at several client libraries and it looks that dependencies come mostly from IP stack, so there's very little to be implemented to have it running.
You should expect the proprietary OS issues to be thing of the past in short time - newer terminal lines are based on linux.
I downloaded FreeRTOS port for STM32F4-Discovery from https://github.com/wangyeee/STM32F4-FreeRTOS and I managed to compile it and flash it to the board, but I don't know what to do next. I would like to verify that it is working.
I tried to use debugger and I saw that after reset the program is in function deregister_tm_clones and the board does nothing.
What to do next?
Thanks

You have the code, so can look to see what it is doing. Alternatively you can ask the author of the code by contacting them via github - if you do that they will see the question, if you post a question about there code here then it is unlikely they will see it.
Alternatively there are lots of resources available on the web to help you. For example there is an (old) documented port to that chip on the FreeRTOS website here: https://www.freertos.org/FreeRTOS-for-STM32F4xx-Cortex-M4F-IAR.html ST's STM32Cube software will create FreeRTOS projects for you http://www.st.com/en/development-tools/stm32cubemx.html - and if you just want to learn FreeRTOS you can download a free book here https://www.freertos.org/Documentation/RTOS_book.html
I installed devstack,Now I am trying to connect devstack through jcloud heat api.Can anyone can share any sample application or code for heat api implementation.
Thanks
jclouds doesn't support the OpenStack Heat API at this time. Please feel free to open an issue in our JIRA issue tracker. It also helps us if you specify which API calls are most important to you so we can prioritize those.
I need to use RabbitMQ in one of my projects. On googling I got to know that the library for RabbitMQ is not compatible with BlackBerry. In some posts in StackOverFlow itself someone has suggested to use STOMP protocol in J2ME as RabbitMQ supports STOMP upon adding some plugins. But I couldn't find a library for STOMP in J2ME as well.
Has anyone used RabbitMQ in Blackberry? Any help will be much appreciated.
Thank you very much in advance.
I converted the Gozirra Stomp Java Client code for J2ME you can download it from
https://github.com/rifatdover/RabbitMQStompConnectorForBlackberry
Build a more traditional web interface for RabbitMQ, then have the BlackBerry client code talk to the web interface.
I want to intercept all network traffic coming and going from a specific application on a Windows XP. How do I get started doing this?
The goal would be to reverse engineer the API used between the local software and the remote software and implement the same API in my own software package.
I can program in anything, Java is the easiest however.
Just use Wireshark, no need of programming anything.
