Comparison of ESP programming platforms

The growing popularity of ESP boards has led to the development of several programming platforms. They allow users to develop applications for ESP modules in different programming languages, such as C++, C, Lua, MicroPython, or using AT Commands. Each of them is very specific and has different advantages. The programming style, efficiency, speed of execution, level of advancement, or memory usage will differ from one language to another. Users mostly base their choice depending on their programming skills and goals of the planned projects. The aim of this work is to determine, which language is the best suitable for a particular user for a particular type of project. We have described and compared the mentioned languages. We have prepared test tasks to indicate quantified values. There is no common rule because each of the languages is intended for a different kind of user. While one of the languages is slower but simpler in usage for a beginner, the other one requires broad knowledge but offers availability to develop very complex applications.

IMPLEMENTASI SMS GATEWAY MENGGUNAKAN VISUAL STUDIO 2010 UNTUK PELAYANAN KONSELING JEMAAT

Kini SMS dapat dimanfaatkan untuk berbagai aplikasi, seperti Mobile Banking, Pooling Interaktif, dan lain-lain. SMS juga sangat bermanfaat di dalam gereja Bethany Kuala Kapuas, salah satunya dijadikan sebagai sistem konseling jemaat. Dikarenakan jadwal konseling antara konselor dan jemaat yang belum efisien. Sehingga konselor sedikit kewalahan dengan hal ini, maka dari itu diperlukan suatu aplikasi untuk mengatur jadwal konseling tersebut. Caranya jemaat mengirim SMS keaplikasi dan nantinya konselor yang bertugas sebagai admin (di jam operasional kantor) akan membalas SMS tersebut yang isinya jadwal konseling dengan jemaat. Aplikasi Pelayanan Konseling Jemaat berbasis SMS Gateway pada Gereja Bethany Kuala Kapuas ini dibuat menggunakan bahasa pemrograman Visual Studio 2010 dan AT+Commands sebagai bahasa perintah yang dapat dibaca oleh modem. Dengan adanya aplikasi ini diharapkan dapat memudahkan jemaat dalam menyampaikan konselingnya, sehingga membantu para konselor untuk melakukan monitoring dengan mudah

Remotely Exploiting AT Command Attacks on ZigBee Networks

Internet of Things networks represent an emerging phenomenon bringing connectivity to common sensors. Due to the limited capabilities and to the sensitive nature of the devices, security assumes a crucial and primary role. In this paper, we report an innovative and extremely dangerous threat targeting IoT networks. The attack is based on Remote AT Commands exploitation, providing a malicious user with the possibility of reconfiguring or disconnecting IoT sensors from the network. We present the proposed attack and evaluate its efficiency by executing tests on a real IoT network. Results demonstrate how the threat can be successfully executed and how it is able to focus on the targeted nodes, without affecting other nodes of the network.

Study on GPRS Mobile Terminal System for Rural Informatization

In this paper, GPRS module, including the design and implementation of the telephone terminal interface circuit design TV interface circuit, interface GPRS module and starting circuit are designed based on ARM embedded platform. Software is also designed primarily Bootloader and Linux kernel porting, system part of the driver, the results of the design through experimental verification, the results show that the system can communicate data, you can use AT commands to achieve messaging and voice capabilities.

Design of Soil Temperature and Humidity Remote Monitoring System of Tea Garden Based on GPRS

This document analyze the important impact of soil temperature and humidity on the tea trees growth, and design a kind of remote monitoring system of soil temperature and humidity of tea garden based on GPRS. In this system AT89C2051 is used as controller, and it control SHT11 timing collect soil temperature and humidity information, and using AT commands control the GPRS module to access internet, establish TCP connection between the detection terminal and the data center, then remote transmit collection data to monitoring center, store and manage data by database. The application results proved that the solution is feasibility.
