WeatherLink IP Not Responding to Vantage Protocol

[killic]

Hello,

My WeatherLink IP accepts TCP connections on port 22222 but does not respond correctly to the Vantage protocol:

• Errors: "Unable to wake up console"
• Errors: "Broken pipe" during communication attempts
• Unable to read EEPROM at address 0x2D
• Device does not transmit continuous LOOP data

Current firmware: 115
Hardware version: 111

The device successfully sends historical archive data when WeeWX first connects, but then stops communicating and disconnects. I've tested with both a Proxmox LXC container and a Raspberry Pi 4, with the same results. The TCP connection is established successfully (verified with netcat), but the Vantage protocol communication fails.

I've tried:

• Restarting the WeatherLink IP (power cycle)
• Testing from different systems (LXC container and Raspberry Pi)
• Verifying network connectivity (TCP port 22222 is accessible)
• Using WeeWX 5.2.0 with the standard Vantage driver

The WeatherLink IP continues to upload data to WeatherLink.com successfully, but local connectivity via the Vantage protocol does not work.

Can you help me resolve this issue?

Thank you,

Additional testing:

• Tried with loop_on_init = True to skip archive download
• Result: Still "Unable to wake up console" and "Connection reset by peer"
• The device refuses even the basic wake-up command
• TCP connection works (verified with netcat) but protocol communication fails immediately
