Ideas for improving Smart Config

This blog posting is me thinking out loud about how to improve the flawed Smart Config process. However by the end I essentially come to the conclusion that there's not much that can be done. So unless you're interested in seeing what ideas I had and why they don't...

People talk about a coming Internet of Things (IoT), pervasive small cheap headless devices that connect to the internet and do things like keep your plants watered. When you connect a new device to your home network you have to tell it the name (SSID) of your network and the...

CC3000 Smart Config and keyphrase recovery

Having previously described how the SSID and keyphrase are transmitted to a CC3000 enabled device I thought I should put my money where my mouth is and prove that it's possible to create an application capable of recovering such information. This proved a bit more difficult than...

The CC3000, 802.11n and MIMO

MIMO creates a significant issue for the CC3000. Most modern wifi access points (APs) support at least the following three 802.11 protocols: 802.11b which supports 11Mbs. 802.11g which supports 54Mbs. 802.11n which supports up to 600Mbs. Such APs by default generally operate in...

CC3000 Smart Config and AES

One can use AES with the CC3000 and Smart Config - this will prevent arbitrary third parties who do not know the relevant AES key from recovering the passphrase when transmitted by a Smart Config setup application. AES uses symmetric keys - the same key must be known to the CC3000...

Initially TI clearly documented how the SSID and password were transmitted to a CC3000 enabled device in their "CC3000 First Time Configuration" document. However with release 1.10 they changed the approach to one called Smart Config and now document the API but no longer...
