Uplink Messages
Raw CBOR uplink messages from Thingsee PRESENCE — measurement data, system info, and diagnostics transmitted over Wirepas mesh
CBOR Reference
Raw Wirepas CBOR message specification for Thingsee PRESENCE — for customers operating their own gateways and cloud infrastructure
Overview
This section documents the raw CBOR-encoded messages transmitted between Thingsee PRESENCE and the Wirepas mesh network. Most customers do not need this — the Haltian IoT platform handles CBOR encoding/decoding automatically.
When do you need this?
You need this reference only if you:
- Operate your own Wirepas gateway infrastructure
- Decode raw mesh network messages in your own backend
- Send configuration commands directly over Wirepas (bypassing the Service API)
Communication Basics
- Wirepas endpoint:
21/21 - Encoding: CBOR (Concise Binary Object Representation)
- MQTT topic:
haltian-iot/wirepas/gw-event/received_data/{gateway-id}/sink1/{network-id}/21/21
Each message is identified by a tsmId (message structure ID). The gateway adds metadata fields (tsmTs, tsmGw) before forwarding to your backend.
For general CBOR encoding/decoding guidance, see CBOR-JSON Conversion Reference.
