A quick question from one reader after publication of Smartwatch BLE to Trigger IBM Watson IoT Event was "can I measure the distance in meters and broadcast?". The answer is - it is not reliable with easy formula against a single BLE device. If we were using Raspberry Pi, then we could think of using complex coding. BLE technology and works with Indoor Location Positioning is not new. RSSI … [Read more...]
Detect Samsung Smartwatch BLE and Trigger IBM Watson IoT Event
We can trigger ESP32 to send message to IBM Watson IoT in Presence of a Particular Samsung Galaxy Smartwatch. This involves BLE and WiFi. In our one series of articles on Samsung Smartwatch as Proximity Switch, we triggered a local event, such as control of a relay. In our other series of articles, we sent message to IBM Watson IoT with upon pressing a button (this guide and this guide). Now, … [Read more...]

Influence of Digitalization on Marketing : Part II
This is the continuation of first part of the series. A company can only be successful if it pursues clearly defined goals. The term goal is a desired result for the future. To be able to define a goal, it has to be analyzed where you are and where you want to go (e.g. increasing sales, increasing market share, increasing customer satisfaction). These goals can be pursued and implemented through … [Read more...]
Influence of Digitalization on Marketing : Part I
The customer now spends more time online than ever before. It matters less whether on the desktop PC or mobile via smartphone and tablet. Regardless of the time, location and end device, they are strongly networked and require information in real-time. Around 50 per cent of the population in the developed & developing countries already uses the Internet every day, and one in five now also uses … [Read more...]
Solve ESP32 Sketch Too Big Error on Arduino IDE
Sketch too big is a common issue faced inside Arduino IDE while working with BLE. Most of us set up the Arduino IDE for ESP32 and forget to alter any other settings of the IDE because except some situations, we never face this problem. The error will suggest you navigate to this official webpage of Arduino (which is not exactly related to ESP32), which will tell you … [Read more...]
Big Data and AI Creating More Humane Customer Service
The use of Big Data and AI will change our everyday work more. When used correctly, they not only can drive the level of automation, but also contribute to more humanity. Regardless of whether Big Data and AI help a commuter to navigate an expert or not, they relieve the peoples from repetitive and error-prone tasks. The more Big Data and AI are been applied to everyday problems, the more it … [Read more...]
DIY IR Blaster Circuit For Smartphone
An IR blaster emulates an infrared remote control to control devices such as a DVR or VCR, Air Conditioner, Television and so on. IR blaster was a common feature of Nokia's most of the mid-range smartphones of the 2000 era. Most of the manufacturers (read Samsung) have stopped including this feature at least in the mid-range phones. This is not just another article to join two IR LEDs with a 3.5mm … [Read more...]
Samsung Smartwatch as Proximity Switch : Part V [END]
This is the final part of the series. In Part I, we talked about the basics which continued to Part II. Part III had a working code non-specific to any particular device. Part IV had a partially working code specific to a particular device. circuitdigest.com's code (in Part IV) was not working with Samsung Galaxy Watch LTE. Samsung's smartwatches shutdown both BLE and traditional … [Read more...]
ESP32 BLE Server with Android App
BLE only works when one communication is active and stays ON. Else it remains in sleep mode. Beacons are great usage of BLE. In our series of articles on Samsung Smartwatch as Proximity Switch, we have used the ESP32 as client. In this article, we are talking about using ESP32 BLE as a server. In our series of articles on Samsung Smartwatch as Proximity Switch, we discussed GATT Service and BLE … [Read more...]
Can We Reprogram a Musical Greeting Card Circuit?
The easy time-saving answer is "do not try". All of them are cheap. The original "chip corders" were developed by Richard Simko, sold by ISD could record 20 seconds of the analogue signal. Later, Nuvoton acquired ISD and developed for longer record times at relatively inexpensive end cost. A web search with the phrase "Chip Corder" should give you plenty of examples of the chips. If there is a … [Read more...]
