NMEA Data can be read and written to the TackTick system over a Bluetooth link. This page explains this process in more detail.
Receiving: NMEA data send by TackTick server to SailClever
SailClever can recognize the following NMEA sentences: GLL, HDM, MWD, RMC, VDR, VHW, VTG, VWR and VWT. The program therefore has access to live Boat speed, Heading, Position, Wind and Tidal data.
Transmitting: NMEA data send by SailClever to the TackTick server
The parameters listed in the below table can be sent using the proprietary TackTick free form sentences (FF1, FF2, FF3, and FF4) and standard NMEA sentences (RMB).
| Start | Navigational data | Performance |
| Boat lengths from line | Angle to the mark | Target Boat Speed |
| Start Countdown | Bearing to waypoint | Target downwind TWA |
| Distance to waypoint | ||
| Course to steer | ||
| Stored upwind heading | ||
| Turn | ||
| Cross track error | ||
| Waypoint closure velocity |
If you set-up the PDA as the active navigator then it will automatically transmit all the relevant navigational data to the boats instruments. The advantage of this is that you will no longer have to manually input the route or individual waypoints into the system as you go. Put the route into the PDA and it will take care of the rest!
Choose what data to send and when to send it
Because pushing buttons on the displays during the race is time consuming and distracting the application allows you control what data is send during various stages of the race from before the start to the beat, reach and run. This is achieved by changing what data is sent back on a given free form sentence. For instance say your top display was showing FF1. Before the start it could be set to show Distance to the Line, then after the start it would automatically switch to showing target boat speed. The advantage of this approach is that you will not have to manually change anything, as everything will be taken care of by the application.
Connection Details
You need to connect four wires to the instrument server. Full instructions are given in your TackTick manual.
