After the Lab Comes the Real Test

In the previous case, an IoT solution provider used the PC-based Gravitation tool to validate Wi-Fi R-Mesh in the lab, including topology visualization, fault simulation, and self-healing tests. But once the product leaves the lab, the real challenge often begins during installation.

In applications such as smart lighting and PV microinverters, many vendors are turning to Wi-Fi Mesh because it offers clear benefits: no dedicated gateway, higher bandwidth, and faster OTA updates.

But when dozens of nodes need to be deployed, one problem becomes obvious: bulk provisioning is too slow and too manual.

Installers cannot realistically connect 20 or 30 lights or sensors one by one over Bluetooth and enter Wi-Fi credentials for each device. If one device is missed or entered incorrectly, follow-up troubleshooting can take a long time. This is also one of the biggest concerns customers have when evaluating multi-node Wi-Fi solutions.

How MGravitation Simplifies Deployment

To solve this problem, Realtek built an efficient provisioning method into its R-Mesh solution and implemented it in the open-source mobile tool MGravitation.

What used to be a tedious setup process is now reduced to two simple steps：

Step 1: Provision the First Node with a Phone

After all devices are powered on, the installer opens the mobile app. The phone scans nearby R-Mesh nodes over Bluetooth. The installer selects any one node from the list and sends it the local Wi-Fi SSID and password.

Once that first node connects to the router, the first step is done.

Step 2: ZRPP Zero-Touch Auto-Provisioning

The rest is handled by ZRPP (Zero-Response Provisioning Protocol).

All remaining unprovisioned devices automatically scan Wi-Fi channels, find the first node that is already online, request the Wi-Fi credentials, and connect to the router one after another in the background.

In measured tests, once the first node is online, the other 20-plus devices can all join the network within about 30 seconds. No extra manual action is needed.

Open Integration for Branded Apps

For brands and solution providers, the main value of MGravitation is not as a standalone app. Most do not want end users to download a separate app from the chip vendor.

What they really want is for their own branded app to offer the same fast provisioning and network visualization.

That is why MGravitation is open source. It exposes the underlying communication protocol and interaction logic, so development teams do not need to build the workflow from scratch. They can integrate ready-made modules into their own app and shorten development time.

After customization, users can get features such as:

• Clear network structure: Parent and child relationships are shown in a simple hierarchy, so the overall network is easy to understand.

• Connection quality scores: The app can turn Wi-Fi signal strength into an easy-to-read score. If a device responds slowly, users can quickly see whether poor signal is the cause.

• High-bandwidth bulk OTA: When firmware updates are needed, new firmware can be pushed to all nodes in one batch from the phone.

From Deep Diagnostics to Fast Deployment

Together, the PC-based Gravitation tool and the mobile MGravitation tool form a complete R-Mesh workflow—from lab validation to on-site installation and end-user management.

R-Mesh is not just a networking chip. It is a practical solution that turns complex network technology into features that are easier to deploy, easier to manage, and easier to use.
