What are we doing right with Artemis? What are we doing wrong? Let us know here!
#215966
Since I cannot run the inbuilt BLE - not sure when, I use a standard HC-05 which I can run without anyproblem.
Then I want to display messages using the Zio OLED. The display is not working. But if I run the OLED example, it works.

Any assistance will be appreciated.
