Introduction to Cisco Sensor Connect for IoT Services
The Cisco Sensor Connect for IoT Services solution enables delivery of advanced BLE capabilities over Cisco Catalyst Wireless infrastructure. The key component of this solution is the IoT Orchestrator which is a Cisco IOx application that can be deployed on any existing Cisco Catalyst 9800 Wireless Controller platforms running software version Cisco IOS-XE 17.15.1 and later. With the Cisco Sensor Connect for IoT Services solution, you have capabilities to securely onboard and control BLE devices, and consume data telemetry using the Message Queuing Telemetry Transport (MQTT).

Note:
● Cisco Catalyst 9115 AP is supported with Sensor Connect for IoT Services feature for scanning and advertising. Cisco does not recommend using this AP model for delivering high density, latency-sensitive, or mission critical BLE use cases due to known hardware performance limitations.
● For information on the VIDs for the access points, see the How to Identify Affected Products section in the Field Notice.
Supported Platforms
● Cisco Catalyst 9800-L Wireless Controller
● Cisco Catalyst 9800-40 Wireless Controller
● Cisco Catalyst 9800-80 Wireless Controller
● Cisco Catalyst CW9800M Wireless Controller
● Cisco Catalyst CW9800H1 and CW9800H2 Wireless Controllers
Software Features
New Software Features 1.1
| Feature |
Description |
| Support for MQTT Message Batching |
To improve network efficiency and achieve high MQTT throughput in scale scenarios, the IoT Orchestrator application supports MQTT message batching. As a result, a new protobuf message called DataBatch has been introduced. It acts as a wrapper for multiple data subscription messages, and each DataBatch message can contain multiple DataSubscription messages. The partner application that consumes MQTT messages from the IoT Orchestrator must update the data application protocol buffer from the Pre-GA Release prototype to the GA Release prototype. For information on the Data Application Protocol Buffer (Pre-GA Release), see the https://github.com/ietf-wg-asdf/asdf-nipc/blob/nipc-asdf-01/proto/data_app.proto. For information on the Data Application Protocol Buffer (GA Release), see the https://github.com/ietf-wg-asdf/asdf-nipc/blob/cisco-iot-orchestrator-1.1/proto/data_app.proto. |
| Support for Multiple MQTT Data Receivers with Shared Subscriptions |
A Shared Subscription is a feature in MQTT that allows multiple clients (subscribers) to share the workload of receiving messages from a single topic. It also helps achieve high MQTT throughput by preventing a single subscriber client from becoming a bottleneck. For more information, see the Cisco Sensor Connect for IoT Services Programmability Guide. |
| Support for Application Events |
Application events apply to use cases that require BLE device connection. If a BLE device is connected and any of the following scenarios occur: • IoT Orchestrator application restarts • Cisco Catalyst 9800 Wireless Controller reloads • Cisco Catalyst 9800 Wireless Controller HA switchover Then the partner application must register for the application_events topic to receive notifications such as Application Restarted or Application Stopped. For more information, see the Cisco Sensor Connect for IoT Services Programmability Guide. |
