NMEA2000-Gateway with ESP32
|
|
===========================
|
|
|
|
Based on the work of
|
|
* [Homberger](https://github.com/AK-Homberger/NMEA2000WifiGateway-with-ESP32)
|
|
* [Timo Lappalainen](https://github.com/ttlappalainen/NMEA2000)
|
|
* [Arno Duvenhage](https://github.com/aduvenhage/ais-decoder)
|
|
and a couple of other open source projects.
|
|
Many thanks for all the great work.
|
|
|
|
Goal
|
|
----
|
|
Have a simple ready-to-go ESP32 binary that can be flashed onto a [M5 Atom CAN](https://docs.m5stack.com/en/atom/atom_can), potentially extended by an [Atom Tail485](https://shop.m5stack.com/collections/atom-series/products/atom-tail485?variant=32169041559642) for NMEA0183 connection and power supply.
|
|
|
|
But will also run on other ESP32 boards.
|
|
|
|
Modes
|
|
-----
|
|
* NMEA2000 -> Wifi (NMEA0183)
|
|
* NMEA2000 -> USB (NMEA0183)
|
|
* NMEA0183 -> Wifi
|
|
* NMEA0183 -> NMEA2000
|
|
* Wifi (NMEA0183) -> NMEA2000
|
|
* USB (NMEA0183) -> NMEA2000
|
|
* ....
|
|
|
|
Environment
|
|
-----------
|
|
[PlatformIO](https://platformio.org/).
|
|
Should be possible to use [M5Burner](https://docs.m5stack.com/en/download) to flash ready binaries.
|
|
|
|
Pre Build Binaries
|
|
------------------
|
|
In the [release section](releases) you can find a couple of pre-build binaries that can easily be flashed on your ESP32 board using [ESPTool](https://github.com/espressif/esptool).
|
|
The flash command must be (example for m5stack-atom):
|
|
|
|
```
|
|
esptool.py --port XXXX --chip esp32 write_flash 0x1000 m5stack-atom-all.bin
|
|
```
|
|
For the meaning of the boar names have a look in [platformio.ini](platformio.ini) and look for the hardware definitions in [GwHardware.h](lib/hardware/GwHardware.h).
|
|
|
|
Starting
|
|
---------
|
|
After flushing a wifi access point is created. Connect to it (name: ESP32NMEA2K, password: esp32nmea2k).
|
|
Afterwards use a Bonjour Browser, the address ESP32NMEA2k.local or the ip address 192.168.15.1 to connect with your browser.
|
|
You will get a small UI to watch the status and make settings.
|
|
If you want to connect to another wifi network, just enter the credentials in the wifi client tab.
|
|
On the data page you will have a small dashboard for the currently received data.
|
|
On the status page you can check the number of messages flowing in and out.

more to come...
