It is not just easy to use the BLE of Samsung Galaxy Smartwatch. Because BLE of Samsung Galaxy Smartwatch is designed to work with their intended purposes, such as Samsung Flow software. Reading our previous article on GATT will help to understand the basic things we need to know to work with ESP32. We need to obtain the BLE hardware address, Service UUID and Characteristic UUID of the server. … [Read more...]

What is GATT (Generic Attribute Profile) of Bluetooth LE?
Our goal is to make our developer readers aware of GATT. Previously, we have discussed about Bluetooth, iBeacon and some theories on Internet of Things (IoT) such as Communication Standards for Wearable Computing, Influence of the Internet of Things (IoT) on Retail which eventually talked around the topic Bluetooth LE. "GATT Services are collections of characteristics and relationships to … [Read more...]
Send-Receive Message on PC Over Bluetooth From ESP32 Arduino
This guide intended to be for somewhat advanced users of Arduino and Windows 10. We are using ESP32 setup with Arduino IDE in this mentioned way. We need PuTTY as extra software. Unfortunately, ESP32 with Arduino libraries and Windows 10 is far from being perfect. The original target of this guide is to complete these steps : ESP32 will remain connected with the Windows 10 PC via USB for … [Read more...]

Let us first discuss aptitude and apt-get. aptitude, apt-get and apt are front ends to dpkg. aptitude provides a terminal menu interface whereas apt-get does not. Using aptitude TUI as a normal user … [Read more...]
Data Integrity vs Data Consistency
Data Integrity and Data Consistency are for reproducing the correct information. Data integrity is the overall accuracy and consistency of data. A database can be said to be data consistent when the content under question does not give us the chance to infer a contradiction directly or indirectly. Data can be entirely consistent but entirely wrong. So, the phrase data integrity is about the … [Read more...]
Machine Learning in Capital Markets : Part II
This part is the continuation of part I. Machine learning should classify the data transmitted to it as efficiently as possible and without serious deviations. Consequently, all relevant characteristics must be selected and taken into account in order to be able to classify the relevant data. There are a total of three different procedures for annexing the existing data. In contrast to the … [Read more...]
Machine Learning in Capital Markets : Part I
Since the first scientific treatises on the research object of artificial intelligence in the late 1950s, the topic has become increasingly relevant. AI is now used in all newer areas of technology and is continuously being developed and optimized with regard to more efficient uses in the respective areas of application. AI, as such, presents itself as a complex area that on the one hand tries to … [Read more...]
What is Data Integrity?
The term data integrity refers to the correctness and completeness of the information in a database, data warehouse, data mart or in such similar structure. Our previously discussed topic Data Consistency was for a narrower space. As for the databases, the contents are modified with INSERT, DELETE or UPDATE statements, which may result in the loss of integrity of the stored data in many different … [Read more...]
What is Data Consistency?
Data consistency is quite commonly heard both for MySQL like DBMS and big data. With the phrase "consistency", in case of database systems, we want to refer towards meeting the requirement for any given database transaction. That is, any database transaction must only change affected data in allowed ways. For example, if we were storing a number in a database, only the numerical values are … [Read more...]
