Here is the list of Binary files that I have released. I truly suggest that you use the last one.
- NMEA2WIFIV30.bin (September 2017) - initial release.
- NMEA2WIFIV40.bin (October 2017) - major release introducing bidirectional transmission as described here.
- NMEA2WIFIV41.bin (October 2017) - identical to V40 except that includes an hardware self test as described here.
- NMEA2WIFIV53.bin (April 2018) - major release introducing support for the TCP protocol as described here and a much more fluid web browser interface.
- NMEA2WIFIV54.bin (April 2018) - same as V53 except no password is needed to connect in AP mode.
- NMEA2WIFIV55.bin (November 2018) - major release. The following was corrected/added:
- in some circumstances nmea sentences with 82 characters were not accepted;
- now if, during the first 5 minutes after starting, no wifi output is set and no serial output on port P3 is set, the multiplexer goes to a deep sleep mode saving power;
- the ESP8266 does not show a strange SSID AP when flashed by the first time;
- when you press and hold SW1 to force a factory setting the Green and Red Leds switch ON for about 2 seconds and then switch OFF indicating that you can release the switch.
- NMEA2WIFIV56.bin (November 2018) - major release. The serial port P1 can receive SeaTalk data and convert that data to Nmea 0183 as described here.
- NMEA2WIFIV57.bin (May 2019) - important release. Wrong SeaTalk1 to Nmea 0183 conversions were corrected.
- NMEA2WIFIV58.bin (May 2019) - minor release. Wrong Depth SeaTalk1 to Nmea 0183 conversion was corrected.
- NMEA2WIFIV62.bin (October 2019) - major release. The following was corrected/added:
- compiled with latest Arduino IDE (1.8.10) and Esp8266 core (2.5.2);
- supports OTA update (no cables to update firmware) - see here;
- AP IP address can now be set different from 192.168.4.1 as explained here or here;
- the routing possibilities and the user interface were changed - looks like the Nmea4Wifi with just 2 serial inputs;
- there is a new Simulation Mode which allows to experiment the multiplexer without sensors or transducers connected to the input serial ports.
- NMEA2WIFIV63.bin (January 2020) - minor release. SeaTalk1 to Nmea0183 conversion was revised as described here.
- NMEA2WIFIV64.BIN (January 2021) - major release. The following was added:
- major rework to support new SMD units to be available in 2021
- OTA update is now invoked from the settings web page
- data can be received/transmitted through the USB port
- introduction of Debug Mode
- NMEA2WIFIV66.BIN (April 2021) - minor release. The following was added:
- Simulation works even if port P1 and/or P2 are not set to get data
- Debug mode works even if only P1 is set to get data
- bug corrected in SeaTalk to Nmea conversion of longitude
- OTA update was improved and produces a Success message
- NMEA2WIFIV68.BIN (March 2022) - medium release. The following was added:
- interrupt timings on port P1 was revised once more
- conversion from SeaTalk1 datagrams to Nmea0183 sentences was revised based on the recent work of the NMEA3WIFI multiplexer. Debug information on the received datagrams is now much more informative
- when the multiplexer connects to an external network you can access it either using its IP address in the external network or using "http://NMEA2WIFI/LOCAL" - (may need further testing)
- a bug was corrected that, in very few cases, was causing problems when users tried to flash an ESP8266 module obtained elsewhere
- the hardware Self Test function was revised. Green and Red leds flash 5 times as in Nmea4Wifi multiplexer.
- NMEA2WIFIV69.BIN (April 2022) - medium release. The following was added:
- A complete revision of the additions of version 68
- More reliable connections to an external network will be noticed
- NMEA2WIFIV70.BIN (April 2022) - minor release. The following was corrected:
- bug in converting datagram 53 to nmea0183 sentence RMC (bad SOG)
- NMEA2WIFIV80_RC.BIN (April 2023) - major release. The following was added:
- all our multiplexers can now work in parallel as shown here
- web interface was improved to show correctly in different browsers
- wifi connectivity much improved
- setup information sent at power up on USB at 115200 baud
- NMEA2WIFIV81.BIN (December 2023) - minor release. Same as V80_RC.
- NMEA2WIFIV82.BIN (April 2024) - major release. Following improvements were added:
- TCP port number not saved in EEPROM (thank you Ziga!)
- internal bug in stopping serial ports
- unprotected AP and NULL passwords as explained here
- increased output buffer on P3 and possible dropping as explained here
