Shipped for Robothon2021 Competition

This release contains the code shipped with the Competition Taskboards used in the Robothon 2021 competition June 2021 (www.robothon-grand-challenge.com).

Key Device Features

• Offline mode to provide self-contained task trial clock and task board state displayed on device screen. Hold M5 button on power up to enter offline mode.
• Wifi greeter to allow end user to connect the IoT taskboard to desired internet AP 192.168.4.1. pw "password" (no-WPA2 support), device defaults to attempt to connect to wifi. Wifi credentials will persist between power cycles.
• Internet dashboard connectivity implemented to report device telemetry to competition task board when device is connected to internet.
• Device can run for at least 1 full trial of 10 minutes on battery power untethered when fully charged
• Minimal USB serial messages implemented for integration with a local robot device
