Do not get NMEA over KBox WiFi

[ronzeiller]

Hello Thomas,

WiFi access point is working on 192.168.4.1
Connection to WiFi is ok
KBox display shows (1) connected
ping is ok => 64 bytes from 192.168.4.1: icmp_seq=4 ttl=255 time=4.410 ms

But then?
For openCPN TCP/IP or telnet a port is needed
How to get datas over WiFi?

[sarfata]

@ronzeiller Have you tried connecting to port 10110 via TCP?

Sorry if this is not explicit enough in the documentation but that is the port for raw NMEA data.

Aaaaahhh, I knew, that I knew this already some month ago!!
Too much time past and too much things forgotten....

Both, access point and client both working!

Now I just have to find out again why only NMEA for engine battery is sent (not the supply voltage), when config is like this:

"wifi": {
    "enabled": true,
    "nmeaConverter": {
      "dbt": false,
      "dpt": true,
      "hdm": true,
      "mwv": true,
      "rsa": true,
      "xdrPressure": true,
      "xdrAttitude": true,
      "xdrBattery": true
    },

Barometer and internal IMU (HDG, Roll, Pitch) are sent

And, why I get continuously
23183;LHI;src/common/comms/KommandHandler.cpp:32|Received error frame!

Thank You Thomas

Smells like a bug ...

It should work looking at the code but maybe it does not. Or maybe something bad happens which triggers the error messages. Can you try to disable xdrBattery and see if you still get the errors?

Conversion is done in SKNMEAConverter. You could add some logs in there too.

Do you have the latest version of the WiFi firmware?

Can you add a debug message here: https://github.com/sarfata/kbox-firmware/blob/master/src/esp/main.cpp#L187

To print:

• len
• kr.getKommandIdentifier()
• kr.dataSize()

For example:

DEBUG("Error details - len=%u identifier=%u dataSize=%u", len, kr.getKommandIdentifier(), kr.dataSize())

Something like it should work. We should see a debug line for every error. This is in the wifi firmware so you will need to update it.
