• Displays “Z” on the leds
• Events from buttons A and B are broadcast on ble and when received are printed on the uart line

The goal is to replace the ble buttons broadcaster with zig on bare metal. This broadcaster is processed by ultibo-ble-observer. Although it has no encryption, no privacy and no authentication, it is still useful for controlling a model railroad in a home or club setting, or at a demo.
