Current Standards
NMEA 0813
- Well known
- Easily hacked
NMEA 2000 (N2K)
- Proprietary
- Standardizes PHY and cabling
- Must register and assign PGNs
- Must buy into the cartel
New Standard
- Wireless out of the box (using Flutter Wireless)
- IPv6-based too much data on wire? Too confusing?
- Open Standard
- Website to register vendor and data codes
- Benevolent dictators of standard
- We approve vendor and data codes
Protocol Details
- Easily tied into standard Ethernet
- L3 Protocol
- IPv6
- Put data directly into IPv6 extension header (header 60 maybe)?
- Data grouped into multicast addresses
- L4 Protocol
- Existing one out there in RFC land?
- SCTP for life critical
- UDP or own raw protocol for normal traffic
- Author an RFC?
- Version number as part of header
- 1 - NMEA 0813
- 2 - NMEA 2000
- 4 - Reef41
Name Brainstorming
Company
- Future Marine, LLC.
- Marine of Things, LLC. (MoT)
- Nauticom, LLC.
- Use Nenticom?
Protocol
- ReefCOM
- Reef41 (R41 protocol)
- Marine41
- N41
Product Line
- Coral
Products
- CoralWind
- Wind, sail, weather station related instruments
- Maybe a separate CoralWeather
- CoralPower
- Engine management
- CoralHead
- N2K gateway, hub for flutter devices
- One version could have wifi
- CoralPatch
- Flutter device that takes an existing device's N2K data and converts it to wireless
Notes
- Solar Power
- Sort of an open version of TikTack product line (now Raymarine)
- Doesn't work 24×7
- In-line power
- Tap into power going to device being measured (with CoralPatch)
Startup Resources
- Protocol standard developer (embedded, protocols, C language)
- IOS/Android app developer for reading data
- Website, outsourced
- Test equipment
- N2K protocol reader equipment
- Office or hacker space with room for permanently located hardware
- Budget for marine conferences (travel, entrance fees)
Benefits
- Wireless from the start
- And Internet of Things based mentality
- Make it easy to put everything on a network
- Cost less than products with N2K markup
- Allow other companies to develop products around the protocol
Challenges
- Reverse N2K without getting sued?
- N2K has huge market share and is industry standard
- Mostly towards recreational market
- Getting the word out: marine conferences, distributors (defender.com)
- Augment existing products or create own?
Research
- Arduino for CoralHead
- Protocol stacks on Arduino (IPv6)
- N2K interface in Arduino,
