Last year when I was designing the BLE App, one of the hurdle we faced was the packet size. I couldn’t send more than 20 bytes of data at once. So I had to created packets of 20 bytes and send them one by one, with some headers for packet information. On the...
I am an electronics and communication engineer by education 1. The most fascinating subjects during my engineering were Antenna theory and Fields & Waves. They were also very difficult and confusing. Mostly because it was just theory and we didn’t have much lab. Also it took me a long time to understand the...
Logic Analyzer is a good tool to have on your work bench. You read about my experiments with cheap knockoff last time. Now I have a Zeroplus LAP Educator1. It’s a 8 channel Logic Analyzer targeted at DIY community. In fact its a part of a kit which includes an Arduino based kit...
As you know I have been experimenting around Bluetooth. Until now it’s mostly on Bluetooth Low Energy (BLE) which I think is much easier to understand and implement[1 At the application level]. Last few weeks I have been exploring the Classic Bluetooth, specially Serial Port Profile (SPP). This is when I found out...
In my fourth semester of engineering I built a logic analyser mostly using analog components and parallel port. After that I had not thought about one. But for last few weeks I have been dabbling with reverse engineering some signals. A logic analyser comes in handy for that. I really wanted to buy...
As you would know I use ESP8266 in every possible way. It’s probably the cheapest board with Wifi chip built-in. When I heard about ESP32, it was a dream come true. ESP32 packs both Wifi and BLE in one single module for less than $10. Given the size of developer fan following 8266...
