4.10.2 Vantage Pro 2 : no <ACK> received from Vantage console

[Matthias Manhart]

I try to connect my Vantage Pro 2 with weewx 4.10.2 running on a raspberry pi 4. The VP2 is connected via RS232 and an adapter to USB (directly plugged into the pi4). Currently the same connection is used with a raspberry pi 3 and the software Meteohub without any problems.

Weewx detects the VP2 and starts with the communication, but after the initial part i see the error "send_data: no <ACK> received from Vantage console".

Any idea, why the initial part is ok and than the error is shown ?

Regards Matthias

I would unplug the USB and plug it back in.   Use the 'dmesg' command to see if it sees the device being unplugged and re-plugged.

Use the 'lsusb' command to see what is connected to your pi.

There may be two things going on here. 

1. Despite having a lot of records that have not been downloaded (513 pages), the final timestamp in the logger memory is earlier than the starting timestamp. This is a sign of logger corruption. See the wiki article Corrupt station memory.

2. But, you are also getting "no <ACK>" messages. From your description, it sounds like you are using a serial-to-usb converter. These are notorious for being unreliable. If you have a second converter, give it a try and see if it does any better.

I exchanged the old Davis datalogger with RSR232 with the Meteo Pi Ethernet. I modified my weewx.conf:

I changed the value "loop_request" from 3 to 1 and made a restart of weewx.

Glad to hear it's working.

It appears that your firmware does not know how to generate LOOP2 type packets. What firmware version is your VP2 using?

Firmware 1.82 was installed in the console during these tests. My console was manufactured 2005 and the latest firmware for this generation of console was 1.90. I could make an update to 1.90 and now weewx is fine with the parameter "loop_request = 3".

That explains it. You need firmware 1.90 or later to use LOOP2 packets.
