Can't get weewx working on a new server

[kiwigander]

Hi all, I'm trying to move weewx to a new computer but getting nowhere fast.

The weather station is a Vantage Pro2 with serial data logger (not USB) communicating with an RS232 port on my old Dell D520 running Linux Mint 17.  I'm shifting my server functions to a new fanless mini-PC with RS232 ports.

The old setup was installed around 2012 and I don't recall updating it (other than the OS) since.  

The new installation is weewx 4.2.0.  I tried the .deb package; when I couldn't get it working I purged it and tried again with the setup.py method and Python 3.  The file structure now looks rather like the old setup.

Anyway, I can't get the new installation to work.  No html page is created.  Here is a snippet of output from dmesg:

I have confirmed that I'm using the correct RS232 serial port on the new server.

If I remove the serial cable from the new computer and plug it back into the old one, the web page updates and continues to update, so the console appears to be happy.

I note also that on the new system there is no /home/weewx/public_html folder.  But otherwise the file structure looks OK to this non-programmer.

I'll be most grateful for a solution or at least a way forward.

If it works on your old computer, but not the new, then there is something wrong with the RS232 port on the new computer, or the driver that supports it. Whatever it is, it is intermittent, as the computer is able to occasionally communicate with  the console.

A few things to try:

1. If the computer has more than one RS232 port, try a different one.

2. Do you have a serial-to-usb converter? If so, you could use that instead.

3. Check dmesg, just to make sure the kernel isn't trying to tell you something. Simply type "dmesg" and check the last 10-20 messages or so.

4. Perhaps your new computer has more RF noise than the old? You could try some ferrite coils around the serial cable. 

5. Finally, it is conceivable that your new computer has an odd default configuration for serial ports. To see what it is using, try this:

stty -a -F /dev/ttyS0

(From the log, it looks like you're using /dev/ttyS0, but substitute as necessary.)

Configuring serial ports is an ancient black art with its roots in the 1970s and I don't pretend to be an expert.

Serial ports will make you pull your hair out for sure...

Lets start with figuring out what your box thinks it sees...

Please post the output of:

• lsusb
• dmesg 
• syslog for the period after a clean powerdown/powerup until you see a login

Also give us some details about:

• your precise hardware config - what computer make+model etc.
• which os+version you're running

Also check out https://www.cyberciti.biz/faq/find-out-linux-serial-ports-with-setserial/ for some other stuff to perhaps try.

Does the new box have serial ports ?  It might be worth thinking about a serial2usb adaptor as an alternate mechanism for hooking things up. Sometimes the few bucks for one is less than the value of your time and stress battling things....

But if you have time, give us the details above so we can get more eyes on the problem...

The new machine is an XCY (that's the brand; bought on AliExpress) fanless mini-PC, Celeron N4100 CPU, 8 GB RAM, 128 GB SSD, 2x gigabit Ethernet, 2x RS232, 4x USB (looks like USB 2.0).  Video is temporarily via HDMI (once the server is set up, that will be disconnected); internet is via Ethernet (unit has Wi-Fi built in but I have switched it off in Network Manager); Apple keyboard is plugged into a USB port and Logitech M570 trackball communicates through Logi Unifying Receiver plugged into Apple keyboard (again, once the server is set up, the keyboard will be disconnected).

New OS is Linux Mint 20.  Output of uname -a is as follows:

Output of sudo cat /proc/tty/driver/serial (truncated after line 4 as lines 4 through 31 are identical) is as follows:

serinfo:1.0 driver revision:
0: uart:16550A port:000003F8 irq:4 tx:610 rx:1151 fe:45 brk:33 DSR|CD|RI

2: uart:unknown port:000003E8 irq:4
3: uart:unknown port:000002E8 irq:3
4: uart:unknown port:00000000 irq:0

The output of that command is just a snapshot.  The first time I repeated it, the tx:, rx: and fe: values did increment (635, 1166, 46, 45) so something was trying to communicate through ttyS0.  Now they seem to be static.  

If human memory is correct, COM1=ttyS0=irq4 and COM2=ttyS1=irq3 since forever, so the serial ports don't seem to be non-standard.

I've looped the serial cable through a ferrite sleeve; no difference.

Output of sudo tail -f /var/log/syslog on a fresh cold boot is as follows:

I'll try the other RS232 port.

[Tom Keffer]

Lots of good information here. I wish all users were as diligent.

The results of stty show some small differences from mine. For example, you have -iexten (the dash means negation), while I have iexten, which means mine enables non-POSIX special characters and yours doesn't. That could matter. Most of the others have to do with echoing characters and translating CR/LF, etc. Some of them could also matter.

Try setting it to "sane" values. This will basically force your values to mine.

stty sane -F /dev/ttyS0

Then try again. That's all I can think of.

-tk

Thank you.  No joy with ttyS1 either (and yes, I did change the setting in weewx.conf!).

Still using ttyS1, I tried

stty sane -F /dev/ttyS1

but it's still not working.

Restarting the daemon, then

sudo service weewx status yields (repeatedly, the block of messages doesn't alter) the following:

And sudo cat /proc/tty/driver/serial yielded a similar result to the previous: the tx:, rx:, fe: and brk: values incremented until

serinfo:1.0 driver revision:
0: uart:16550A port:000003F8 irq:4 tx:0 rx:0 DSR|CD|RI
1: uart:16550A port:000002F8 irq:3 tx:1123 rx:1654 fe:95 brk:108 DSR|CD|RI

2: uart:unknown port:000003E8 irq:4
3: uart:unknown port:000002E8 irq:3
4: uart:unknown port:00000000 irq:0

and then they stopped incrementing, as if the daemon gave up trying to connect.

I rebooted again and looked at /var/log/syslog again, grep-ing for weewx, and got (sorry for the length here):

I was hoping to avoid USB<=>RS232 converters, as I understood they were problematic (in the past) and would add another thing-to-go-wrong.  I have one other old device to monitor and it too has only an RS232 interface.  Thought I'd be clever and get a low power box with two RS232 ports.

FWIW, i've been running a VP2 with serial datalogger and a serial2usb dongle for something like 10 years now.   I started with a Shuttle mini-pc that had serial ports and switched to a little arm box that just has USB.  Never had an issue with the serial2usb from day one.  Works great.

You basically just want to make sure you get the right chipset in the adaptor.  Anything with the PL2303 definitely works.  Both mine have that chipset, and they were picked up years apart from different suppliers, so they used to be pretty much what you always got.  I haven't looked in years to know if that's still the case.

I'm running on a Seagate Dockstar (a 128MB RAM version of the original PogoPlug) with a Seagate laptop drive plugged in, and you can see the serial adaptor available in the lsusb output below.

Ta.  The prevalent RS232<=>USB chipset around these parts seems to be an FTDI.  I'll look around. 

[Tom Keffer]

I think we can say with some confidence that there is something wrong with the UART chip on your new computer. Can you take it back?

Alternatively, as Vince says, a serial-to-usb converter. They seem to be more reliable these days.

Have you checked that there is not any form of getty running on the port - they wait for logins and will steal some of the input characters.

That's rather old school - I don't know how systemd does it.

[Tom Keffer]

Good point. I've had problems with modemmanager doing this.

sudo apt purge modemmanager

Thanks again for the advice and suggestions.  

I've used stty to see how the ever-reliable RS232 port is configured on the old server and will try setting the new one to mimic it.

I'll try purging modemmanager from the new server.

Assuming, though, that the problem is defective hardware, the new server ought to be returnable but I'd have to send it back to the PRC.  I wonder whether the serial comms module is replaceable -- that might be more cost-effective than sending the unit back.  I'll try a USB<=>RS232 converter anyway.

I'll be offline for a couple of weeks but will report back.

[kiwigander]

Progress report:

I've got a Unitek BF-810Y USB<=>RS232 converter.  Plugged it in to the old Dell; it was recognised as a pl2303 converter on ttyUSB0. Changed the relevant line in weewx.conf, restarted the daemon and we're in business.

I'll have a last go at the RS232 ports on the XCY mini PC but I'm not optimistic about that unit.  

[Tom Keffer]

Sounds like our analysis was spot on. At least you know what the problem is now!

And for the final test before giving up on the XCY mini-PC, I ran sudo apt purge modemmanager

and now weewx is working through /dev/ttyS1 on the XCY mini-PC. 

Some corollary of Murphy's Law says that if a problem is going to be solved, it will be solved by a simple manoeuvre that you ran out of time to try.

Thank you Tom & colleagues!

Now one more thing:

The new server's database starts just a few minutes ago.  The old server's database goes back quite a few years.  How do I merge the previous data onto the new server?

[p q]

copy the database file from the old machine to the new one.

I spoke (wrote) too soon.

Weewx seemed to be working on the XCY through /dev/ttyS1 after modemmanager was purged, but it stopped working.  It looks as if it was still struggling with CRC check errors.  I thought the fault might have been (re-)triggered by an update to some Mint system files and applications (although none seemed likely), but reverting to the previous configuration and rebooting did not help.  So it's back to /dev/ttyUSB0 via the converter, which is working as well on the XCY as on the old Dell.

There's a point in time where the value of your time exceeds the value of the adventure of figuring out why the serial port for your unusual os (on your unusual hardware) isn't as trivial as most setups.  Sounds like you could have bought a new computer with the time-value of battling this one.

Glad to hear the serial-to-usb adaptor worked.  Just stick with it.
