Communication Flow
The purpose of this section is to illustrate the steps the Desk Sign utilizes to boot up and display the availability of a workspace.
#
Description
1
The Desk Sign will automatically connect to the Embrava Cloud requesting its home Function App and IoT Hub using a REST API at https://deskmanagement.azure-api.net/ on port 443 (TCP)
2
The Desk Sign then pulls down its configuration from its home Function App using a REST API at https://eaufuncapp01.azurewebsites.net/ on port 443 (TCP).
3
The Desk Sign then determines its current time using public time server north-america.pool.ntp.org on port 123 (UDP).
4
The Desk Sign then attempts registration with the IoT Hub endpoint received from the Embrava Cloud in Step 2. This is done using a REST API at https://eauhub01.azure-devices.net on port 443 (TCP).
5
Once the Desk Sign receives its configuration, it begins to synchronize bookings with its configured desk by communicating with the IoT Hub at eauhub01.azure-devices.net using the MQTT protocol on port 8883 (TCP).
6
The Desk Sign will download an updated firmware package when it is instructed to via the DMS Admin Portal. This is done securely at https://raw.githubusercontent.com on port 443
