From 31bf214d734c6d7ac8773eb97911219825579ae5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Otto=20Ryyn=C3=A4nen?= Date: Fri, 2 Dec 2016 13:53:22 +0200 Subject: Added IoT SensorTag demo to tradeshow iot-sensortag folder added. This is project originally from consultacy repo, moved to here. It's a cross-platform app that shown multiple data values from TI CC2650 SensorTag.
