Send and read a Bolt serial reply
Ask for a device response and receive the round trip in one workflow.
Trigger
New WhatsApp Message Received
Polling trigger that monitors for new messages received in TimelinesAI WhatsApp chats.
Action
Bolt IoT Serial Write & Read
Tool to send serial data and read the response on a bolt device. use when you need to transmit ascii data over uart and capture its reply immediately.
Why this helps
Testing request and response behavior manually takes too many steps.
- Capture immediate replies
- Simplify device testing
- Keep request and response together
Setup
Build it in a few focused steps.
- 1Connect TimelinesAI and Bolt iot in Notis once.
- 2Create an automation that sends the requested ASCII payload and reads the immediate response from the named device.
- 3Pick New WhatsApp Message Received as the trigger.
- 4Select a report channel and test with a known request and response.
