Back on AWS IoT Core

After some time away on other systems, I have had a project purchased for a customer running a module from China from Quectel.  It is a nice little module which supports MQTT however the solution that it runs was unable to connect to AWS IoT Core for love or money.   I love AWS and cloud instance of MQTT brokers in general, but the problem with it not being your own server is that these types of issues are extremely hard to debug.  At first I thought the Quectel module wasn't processing/presenting the certificates and/key properly or it was strongly to validate the server's certificate corr

Shift to Github and Git

Just a short know note to let you know that we've now completed shifting all projects over to Github for both bug tracking and repositories.  These are all private projects, but due to the amount of opensource code that is now hosted on Github it makes it much easier to maintain these submodules.  If you have any issues with access please let your program manager know.  We will continue to maintain BugZilla and SVN repositories as an alternative (or for highly sensitive programs) but this will no longer be the default.
