retrieving old data from DAVIS VANTAGE PRO2

[Frank von Thienen]

Hi,

Yesterday I set up my weewx after a crash (1 year ago).

The system is writing to an external MySQL, which works.

But while loading old data from the DAVIS, I get the following info in the log.

Is that an issue, since I cannot find those daily summery somewhere to check.

Thanks

swapping back to SQLite, it runs into the db without a problem.

So it has something to do with the SSH Tunnel and the external MySQL, connection to slow?

That seems odd, the error shown is the driver encountering a crc error on data downloaded from the station. The driver has no access to the database so I can’t see how the database in use could cause a driver crc error. If you change back to MySQL again does it work?

Hi Gary,

sorry for beeing late, but the job is difficult at the moment, Software release for a big furniture dealer in Germany.
If swapping back, I get the same errors again, SLQite no issue, MySQL error.
But the normal readings of the actual values are correct retrieved. So MySQL is storing the 15 minutes values, but not reading the backlog import.
And that is odd

Thanks

Frank

Could we see a little more of the log? If the driver is unable to download a page of memory from the logger, it should do a retry, yet I am seeing only one try. What happens after the snippet you posted?
