Today, I will present Xamarin Forms (XF) mobile application (iOS and Android) which talks to the vehicle. I will present demo app which reads vehicle speed, engine revolutions per minute-RPM and some other data, such as engine temperature. For that I will use: Xamarin Forms as mobile development framework, On-board diagnostics – ODB2 as car […]
A little bit of background. Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks. It was originally conceived as a wireless alternative to […]
In this blog post I will not only stick to technical side of the problem, but I will also put some thoughts on how sometimes in development everything goes wrong. And how to deal with the situation, till you get the solution. iOS13 was released on September 19th. Quickly after release, on one of the […]

Commonly, on one side of the communication you have some hardware or maybe some IoT device, while on other, there is some mobile app or similar. When doing geenfield projects, normally you don’t have everything in place on the device side, but you need to develop Bluetooth […]
