RaceData2 was designed for use with Expedition Navigation Software running on a computer with both devices connected to the same WiFi network.
Other options are:
A+T instruments broadcasting Expedition UDP data
NMEA0183 UDP data from other systems with a NMEA0183 to WiFi bridge such as products from Antisense, Digital Yacht, Yacht Devices, ShipModul, Quark-Elec
No.
RaceData (Android Watch), RaceData2 (Android and Apple) phones and tablets and RaceData3 (Apple Watch) will all work over WiFi.
You do not need to install any additional hardware (Bluetooth, ANT+ or other) for any of these products to work on your boat, and you don't have to have your watch tethered (Bluetooth or otherwise) to your phone.
No. Broadcasting on, for example, 192.168.1.255 means that any device on the network within the IP range 192.168.1.xxx will be able to receive data on the specified Port.
For Apple Watches wanting to operate in standalone (Exp Bridge) mode independent of a paired iPhone, a separate Expedition TCP Network port must be configured for the RaceData3 Bridge application.
The free version is designed for you to check functionality before commiting to a subscription.
It includes TWS, TWD, HDG and BSP in a 2×2 grid layout with one data page.
On an unlocked page, tap any data cell to open the channel picker. Select the channel you want to display. You will only see channels that are being received.
Subscribers get access to all Expedition data channels (including custom user channel names), data graphs with rolling average and EMA indicators, multiple data pages with various layouts (up to 3×5 grids), and the ability to control Expedition (start pings, timers, marks, and MOB).
Tap the page menu or swipe between pages, then use the page menu to add a new page. Subscribers can create unlimited pages; free users are limited to one page.
Yes, tap the Page icon and tap Lock Page.
When the screen is tapped, a small padlock appears on the bottom right of the screen, press and hold to unlock.
Due to limitations with Android and iOS systems, receiving data over UDP/WiFi with your phone locked is not permitted.
Options:
In Settings, use the 'Screen Always On' function. To save battery, you can use the 'Dim in Pocket' setting.
Android has an additional 'Keep RaceData2 on top' feature.
On an iPhone, to keep the App on top, use Guided Access:
Initial Setup (one time):
Settings → Accessibility → Guided Access
Turn on Guided Access
Set a passcode (or use Face ID/Touch ID to end sessions)
To enable:
Open RaceData2
Triple-click the side button (or home button on older iPhones)
Tap "Start" in the top corner
To exit:
Triple-click the side button again and enter passcode
This is often caused by WiFi signal or Network configuration issues. Low quality (read cheap) routers and antennas can be problematic. Please consult with your navigation systems installer.
Check these common causes:
Both devices must be on the same WiFi network
The Rx port in RaceData2 must match Expedition's transmit port
On iOS, ensure Local Network permission is enabled (Settings → Privacy & Security → Local Network)
Check that Expedition is actively transmitting data in the Raw data window
In RD2 use the Raw Data monitor in Settings to see if packets are arriving
Check your IP and Port settings. You can confirm communication using 'Ping'.
If you change your IP or Port settings you may need to refresh your 'listener'. To do this, simply disable then enable Data Listening.
Android toggle off/on Data Listening
iPhone 'Stop Listening' then start again
These dots indicate the 'freshness' of the data you are viewing.
Dot Colour | Last data recieved |
Green | <10s |
Orange | 10s> <20s |
Red | >20s |
Expedition UDP protocol only sends data when the value changes, therefore Orange or Red dots do not necessarily mean that you have lost connection.
If you have some data with green dots, and one with orange or red, this indicates you have a static number, for example mark range on a very long leg.
Expedition UDP protocol only sends data when the value has changed.
If you are, for example at the dock, HGD will only be sent when your Heading changes so you may see an empty data box. Similarly, if you want to change a channel in a data field, HDG might not be available to select if it has not been received before.
