Step 5. As soon as power is applied to the radios, all of the LEDs will blink once. After powering the radio, hold down the Power button for 2 seconds to turn the unit on. The Power LED will blink until the unit has fully booted, at which point it will be steady.

Note about attenuators: The following photo is of the attenuators included in the mini-OEM, nano-OEM, and OEM evaluation kit. They are used to reduce the signal strength of the radio. Be careful not to have them installed when trying to optimize for range. 

Connecting to the Radio

There are multiple ways to connect to the Mesh Rider Radios: WIFI (Wearable and OEM only), Ethernet , USB Device, USB Host. We will only cover WIFI and Ethernet as these are the most interoperable across different operating systems. 

 

Wi-Fi Connection (only for wearable and OEM) 

You can connect to the radio over its built-in Wi-Fi radio. By default, the built-in Wi-Fi radio starts up an Access Point with SSID DoodleLabsWiFi-<last 6 hex digits of MAC> and password DoodleSmartRadio. No cables are required for this connection method.

 

Ethernet Connection

Wearable: Connect an ethernet cable to connect from the RJ45 connector of the  USB-W04-A dongle to your host machine. 

 

mini-OEM/nano-OEM/OEM: Connect an ethernet cable from the RJ45 connector of the evaluation board to your host machine. 

 

Please refer to the Wearable User Guide if you wish to use USB.

Network setup 

After establishing a connection through either WiFi or Ethernet, you must set a static IP address for your host machine within the 10.223.0.0/16 subnet to access the radios. The method for assigning an IP address differs between operating systems (Windows, macOS, Linux, etc.). 

For a Windows 10 or later system, navigate to the Network Connections folder in the Control Panel. Right-click on the Wi-Fi or Ethernet adapter your host is using and select Properties. In the properties window, choose Internet Protocol Version 4 and then click Properties. Set the IP address to the 10.223.0.0/16 subnet. Since these addresses are statically assigned, make sure not to use the same IP address for another device on the network. Refer to the figure below for guidance on manually setting the IP address. The process is generally similar for macOS and Linux.

 

After setting a static IP address, open a web browser and navigate to the IP address printed on the label of the radio.

When first visiting the page, you may see a warning about the authentication certificate. This can be disregarded since the Mesh Rider Radio employs a self-signed certificate. You will need to acknowledge this warning and click proceed to continue. This process varies between browsers, but will likely look similar to the below screenshot.

 

Upon reaching the login page, you'll find that there is no default password set. You can click Login (with no password) to log in. After logging in, the Simple Configuration page will be displayed (this applies to firmware from October 2022 and later. If your firmware is older, navigate to Network -> Simple Configuration).

 

 

The default configuration of the Mesh Rider radios allows Mesh Rider radios of identical band models to automatically form a mesh on first boot-up without any configuration changes. You can immediately run IP-based connections over the Mesh Rider network.
