TI SimpleLink SensorTag 2015

I recently came across the TI’s latest SimpleLink SensorTag and was immediately intrigued.  Here is a device that for $29 gets you Bluetooth Smart packaged with a microcontroller and 10 sensors in a compact package all powered by a CR2032 coin cell.

I decided to pick on up along with the $15 Debug DevPack.  They arrived this past Friday and I took some time over the weekend to start looking them over.


The initial setup is about as easy as it gets.  Open the box, pull the battery tab and download software from Google Play for Android or iTunes for Apple IOS.  In my case I installed the Android app on my Nexus 7 2013 and was off an running.

The Android allows you to access a number of the sensors and get real-time data from them.  It also allows you to perform over the air firmware upgrades.  It is a great launching point for getting to know the SimpleLink SensorTag better.

It Worked For Me - Arduino Pro Mini DTR Reset Fix

I am not sure what happened but all of a sudden the DTR Reset on one of my Arduino Pro Mini boards stopped working using my 3.3V FTDI Basic.  Using an SN3904 NPN Transistor I was able to get it working again.
