Factory Reset

To factory reset, hold down both the Turbo button and the Power button until the indicators all start flashing. After that, release the two buttons and wait for the device to reboot. A factory reset may take up to 5 minutes. Do not power down the unit during the factory reset.

Initial Setup

Hardware setup

Attach the battery to the Multiband Wearable radio following the guidelines above, and the antennas provided in your evaluation kit to the TNC-Female connectors.

• 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.
• While booting up, both the Wi-Fi and Mesh Rider indicators will blink. They will switch to a slow blink after boot-up while waiting for a connection. If you have turned on any other radio, the Mesh Rider indicator will eventually hold steady once the radios are connected.
• If you connect to the radio over it's Wi-Fi interface, then the Wi-Fi indicator will hold steady.

Connecting to the Wearable

The Auxiliary USB-C port uses non-standard wiring to support Ethernet, USB-Host, and UART interfaces. The USB-Host interface uses standard USB2.0 wiring on the USB-C port, so it will work with USB dongles which are limited to USB2.0. USB2.0 USB to Ethernet bridges will be automatically bridged to the Mesh Rider network.

Fig. 6 shows how the USB dongles, USB-W03-A (Locking USB-C to USB-C Power and USB-Data) and USB-W04-A (Locking USB-C to RJ45 Female) can be connected to the Wearable Mesh Rider Radio. See the Products page of your Mesh Rider radio for more information.

Fig. 6 Wearable Mesh Rider Radio with USB-C dongles attached

Wi-Fi Connection

You can connect to the radio over it's 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.

See the Software Setup section for details on IP addressing.

USB Connection (Wearable as USB Device)

Alternatively, you can connect to the radio over the USB port on the front panel. This will require you to peel off the outer sticker on the front panel. You can connect to the radio's USB port from a PC or a smart device (e.g. tablet or phone) which supports USB reverse tethering. In this mode, the Wearable is a USB Device, and the PC/tablet/phone is a USB Host.

If you are powering the Wearable radio externally (not using the battery), then you can use Doodle Labs' power/data cable splitter (USB-W03-A) to split the data and USB ports.

See the Software Setup section for details on IP addressing.

Ethernet Connection

You could also use the USB-W04-A dongle to break out the RJ45 Female connector.

See the Software Setup section for details on IP addressing.

USB Connection (Wearable as USB Host)

As a final alternative, you can use the Wearable Mesh Rider Radio's built-in USB-Host port to connect to a USB Device such as an Android Smart Phone with a USB OTG port. Doodle Labs does not provide a USB dongle for this purpose, however, you can use any off-the-shelf USB-C to USB-A dongle as long as it is limited to USB 2.0. USB 3.0 is not supported, and the USB 3.0 wires should not be connected to the Wearable Mesh Rider radio.

Software setup

The Multiband Wearable Mesh Rider radio uses the same IP addressing scheme as all Mesh Rider radios. Therefore, you will need to assign a static IP address to your host machine in the 10.223.0.0/16 subnet in order to access the radios. This is true for both the USB connection and the Wi-Fi connection. Details on how to configure a static IP address differ depending on your operating system, and guidelines for a Windows 10 PC are shown here.

If you are connecting to the radio over the USB port, then your system will need to have the driver for the LAN9500A chipset installed. It should be available by default in Windows machines, most Linux distributions (smsc95xx driver), and Android devices which support USB reverse tethering. Fig. 7 shows the Ethernet 2 adapter (LAN9500A USB to Ethernet) appearing after plugging in the Wearable Mesh Rider radio in a Windows 10 machine.

The default configuration of the Mesh Rider radios allows them 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. That said, you should at least modify the following settings for security:

1. Add a root password
2. Modify the Mesh Rider radio's SSID and Password
3. Modify the Wi-Fi radio's SSID and Password

You will be prompted to modify the root password the first time you attempt to login to the radio over the web GUI. Open a web browser and navigate to the IP address printed on the label of the device. After changing the root password, you can navigate to the Simple Configuration page.

Fig. 8 Simple Configuration page

This page allows you to modify the most common settings on the radio in one step. Aside from the changes mentioned above, you can optionally

1. Disable the DHCP client if it isn't required. This will leave only the default 10.223.0.0/16 IP address.
2. Change the default channel and bandwidth of the Mesh Rider radio.
3. Change the default channel of the Wi-Fi radio.

Make sure to make similar changes on all other radios to maintain connectivity. We encourage you to read through our guides in the Technical Library for additional tips on working with Mesh Rider radios.

Networking Information

As with all Mesh Rider radios, the default configuration behaves like a wireless ditributed layer-2 switch. Connecting devices to Mesh Rider radios is similar to connecting the same devices to an Ethernet switch. The Mesh Rider network passes traffic over the mesh transparently, and devices which need to communicate with one another need to be on the same IP subnet. Details on the Mesh Rider's networking modes are available here.

General Usage

A simple use case for the Wearable Mesh Rider radio is shown in Fig. 9. In this case, we have three connected workers in a mesh network. Each worker's tablet is connected to a Wearable Mesh Rider radio over Wi-Fi, and is assigned a static IP address. The workers can use applications for team collaboration to enable voice chat, video streaming, file sharing, and locating one another among other things. You can test the latency over the network using the ping utility, and you can test the throughput using iperf.

Fig. 9 Simple connected worker use case

We can add internet access to the simple use case above by connecting one of the Wearable Mesh Rider radios to the LAN interface of a modem/router (this works with any Mesh Rider radio). Since the router typically runs a DHCP server, the tablets should also use DHCP client mode (i.e. automatic IP assignment). The Mesh Rider radio will automatically get an IP address from the DHCP server to go along with the default static one. At this point, the connected workers can still use the same applications to communicate with one another as before, and in addition, they have access to the internet.

In the example above, the Wearable Mesh Rider radio could also act as a gateway to the internet. There are also other advanced features that were not discussed in this guide. For more information, please look through the rest of the Doodle Labs Technical Library.
