Fab Lab at UP
Group challenges
- Learn a new software MQTTX
- Define libraries: NimBLE or BLE with the OLED
- Error and conflict with different libraries
- Learn with videos (You Tube) and Chat Gpt
Group at Fab Lab
Process
During this week we worked on:
- Connecting devices
- Explore MQTT as client/server telemetry communication tool
- Program with Arduino IDE and its libraries
- Interact with different output/input devices
Connecting devices
MQTT Client toolbox installation:
The user interface (UI) of MQTTX adopts a chat-based layout,
simplifying operational logic.
Setup server using MQTT
