Query a Bolt serial device from WhatsApp
Send a defined ASCII query over UART from a WhatsApp request and capture the response returned immediately by the device.
Trigger
New Message Received
Triggered in real time when your WhatsApp Business number receives an inbound message from a customer (text, media, location, or contact). Delivered via the Cloud API webhook.
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
A serial query can be easy to postpone when the request arrives in chat and running it requires a separate tool.
- Start a defined serial query from an inbound message.
- Capture the immediate device response with the same action.
- Keep query results in the Notis run report.
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Bolt IoT once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a clear name.
- 3In one instruction, specify the device, ASCII query, and the WhatsApp wording that should trigger it.
- 4Pick the New Message Received trigger and choose where run reports should go.
- 5Test with one real request after UART has been initialized on the device.
Questions about this workflow
Does this action initialize UART?
No. The action sends ASCII data over UART and captures a response; UART must already have been initialized.
What response does it capture?
It captures the response returned immediately after the serial write. The action does not describe a persistent serial monitor.

Supported Triggers and Actions
Notis builds workflows that link Whatsapp to Bolt iot. A trigger fires from one place; an action lands in another.
Whatsapp triggers
Bolt iot actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Analog Read
Tool to read the analog value from a specified pin on a bolt device. use when you need sensor readings (0–1023) after confirming the device is online.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Bolt IoT Digital Write
Tool to set a digital pin high or low on a specified bolt device. use when controlling actuators or leds via digital output.
Message Status Updated
Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks
Check Bolt device online status
Tool to check whether a specified bolt device is online. use when you need to verify device connectivity before sending commands (e.g., control signals). example: 'check if device bolt1234567 is online.'
New Message Received
