I'm a Electrical Engineer working in the industrial controls industry with a software engineer / general computer nerd bent. A while back I wanted to get into some phone development, and I found that a lot of times on site with a customer it would be really handy to not have to have my laptop to troubleshoot a signal. Well, since where I works deals predominantly in ModbusTCP I thought I could marry the two together.
I found a library that looked good (modbus4j), and sank my teeth into my first Android app
