Dragonfly talking to a ST X-Nucleo demo board. Aeris Aercloud portion is remarked out. Also a portion of the ST Sensors are documented but remarked out.

Looks like you are trying to use some cloudservice. You will first need to register with a personal account and password on that server. These private values should then be stored in your program in the now missing defines for _AERCLOUD_ACCOUNT_ID etc.

I stole the code from a previous class that I was teaching how to use Aeris cloud services. In this example I remembered to remove a number of the Cloud services calls in comments but unfortunately didn't remember to comment out the 3 lines that are causing you problems. The solution is to comment out those three lines of code. You are very correct regarding getting a personal account and password on a server, then the rest of the commented out code could be used to drop the ST MEMS data to the cloud.

Footnote, the MQTT services library that I incorporated only allow 256 bytes of data. There is a better version that allowed 64K data packets that would allow all the data to be transferred in one shot.
