Action
Bolt IoT Serial Write
Tool to send serial data to a bolt device. use when you need to transmit ascii data over uart after initializing uart with serialbegin.
Why this helps
Course files can be added without an obvious cue, leaving you to repeatedly check for updates.
- Start a configured device command when a course file is uploaded.
- Use serial output to connect Canvas activity to a hardware workflow.
- Reduce manual checking for new course files.
Setup
Build it in a few focused steps.
- 1Connect Canvas and Bolt IoT once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a clear name.
- 3Tell Notis which Bolt device and ASCII serial command to use when a new file upload is detected; include any needed UART initialization details.
- 4Pick New Canvas File Upload as the trigger and choose where run reports go.
- 5Test with one real course file upload and confirm the device receives the command.
