Re: Cannot connect to WiFi

Hello Stuart,

Glad you got it working.

From the SesTalk bus you need to bring the 12V wire to A4 and the Data wire to B4. You don't use GND.

Regards, Luis

Re: 2 way communication

Hello, The multiplexer has a nmea0183 output. If the autopilot works with this standard, it can receive data from the multiplexer. I never used that but users told me that they send information from OpenCPM through WiFi (TCP) to the multiplexer with the multiplexer set to route arriving TCP data to ...

Re: Cannot connect to WiFi

Hello, Since you cannot connect and the multiplexer does not creates its network, it could be the case that the update did not finished correctly. You could try to flash the esp32 module as if it was a module purchased elsewhere. There are instructions on the forum how to accomplish that. I am retur...

Re: Updating Firmware Over the Air (=OTA)

Hello Leon, I wonder if you could try to flash the wemos module using a USB data cable as described in the forum. It is not as friendly as using ota but maybe it could solve your problem. I am in Greece. If you are not able to get your problem fixed I can flash a module for you. However only in Sept...

Re: NMEA4 / SailGrib

Hello Bruno,

I would be very happy to change the software with your input but unfortunately I am in Greece until mid September. If you can wait, we could discuss this later.

Sorry for the lack of assistance, Luis

Re: Unable to join network “NMEA2WIFI”

Hello, Do you see the WiFi network Nmea2Wifi? Can you connect to it? If you say that the red led is blinking that means that the multiplexer is working and receiving a is data. You can make a factory reset. Press and hold the switch on the PCB. All LEDs will go on. When they go off ( after 3 seconds...

Re: How to use N4W - setting ... Software

Hello, If you are designing your own hardware and if you don't need galvanic isolation from the data source device to the multiplexer input you just need an inverter. A simple NPN transistor with a pullup resistor to 3V3 will possible do it. The input base resistor should not be too low so that the ...

Re: How to use N4W - setting ... Software

Hello,

Please do not use the Nmea4Wifi exe tool with new versions of the multiplexer. For Android you can use SeaWi to display all the data that the multiplexer sends out.

At this moment I don't know if your autopilot is controlled by Nmea0183. If yes you could do it.

Regards, Luis

Re: Communication (Data not only power) on USB (automatic driver installation on Windows 10 doesn't work, no driver foun

Hello, First of all, no need to patch a resistor like in the old Nmea2wifi multiplexer. The driver for Windows is for the CH340 IC. Please read to the end of this topic to find a link to download the driver: http://www.vela-navega.com/forum/viewtopic.php?f=13&t=239 Also make sure you are using a USB...
