I have used Gazell on RFduino in a couple of applications - internal test tools in my company. I understand that Gazell is a Nordic product but I don't know what SimbleeCOM is.
For a new project I have two tools that will send data to a 3rd tool and I am using Simblee modules.
What are the differences between SimbleeCOM and SimbleeGZLL - how would I choose?
I do not need BLE but I may choose to add it later to improve usability of the design.
