Occasional 'Date Error' on SB2500HF30 #49

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. I have two inverters: SB5000TL and SB2500HF3. 
2 create configuration files as in the attachments to this report. The 
SB2500HF30 is modeled as a 3000TLHF

3. call ./smatool -v -c SMA5000TL.conf
4. call ./smatool -c SMA2500HF30.conf

What is the expected output? What do you see instead?
Expected output is both inverters returning list of data with five minutes 
intervals. In many cases, this is also what is happening.
In some (between one in ten and one in five, I didn't do the statistics yet), 
the second call to the SB2500HF30 fails with

What version of the product are you using? On what operating system?
smatool-0.14
Gentoo linux 2.6.39-gentoo-r3

Please provide any additional information below.
The tool is running without mysql running yet.

I too am seeing this occasional error on the 3000TLHF with versions 0.14 and 
0.15

I am also getting the same last two lines on the debug but with correct data 
above that.
The date range output contains data but the header contains no figures.

I have a SB 2000HF which I have defined as a 3000TLHF as it is not listed.
I will try to do a sniff when using Win XP next.

I'm also seeing this error and it seems to be with certain packets/day or time. 
If I use a fixed -to -from query I can run successfully, but it occurs about 
every 1 to 2 days. 

Here is the -v output. I've attached debug.

bluetooth signal = 67%

I also wonder if it's to do with bluetooth signal strength issues??? as I've 
sometimes had the issue no-repeatable??

Any updates here in regards to a sniff-parse? Seeing same issues however seems 
to occur more often when requesting a larger date query, say for a full day or 
the past week as opposed to requesting 'HEAD' data only.

@3: same here - at times it simply runs flawlessly however even if 75% + signal 
strength i can have a deadlock, giving me same error 5 consequtive times in a 
row.

I have an idea of that letting the inverter disconnect 'properly' while not 
connecting more then once every 3-5 mins helps my issue. But it is simply a 
hunch.

Setup:
  Inverter: SB 2000HF-20
  BT adapter: Cambridge Silicon Radio (HCI mode)
  Tool version: sma-bluetooth-18

Steps:
1: run ./smatool -v -from DATE1 -to DATE2

Observations:
Occational single row-inserts failing (skipping a 5-15 min interval)
At times breaks with no inserts at all (simply two obscure dates containing 
weird power totals.

Dear all, 

I'm using the SB 2500HF-30 with smatool version .18 and I'm seeing same issues 
which based on the next piece of captured data makes me to believe that for 
some reason the wrong part of the string is being used as data causing it to 
produce odd dates and values, most likely due to the high value of the todo 
variable or some other reason which causes this value not to be handled / 
serviced in a timely fashion.

I wish we could find a solution. It doesn't happen all the time, but seems 
rather regular!

Just to add I'm running this on a Raspberry pi - I see a few others with this 
problem when using the pi so I'm wondering if it's pi specific...

No, it's not pi specific. I have it on various PCs.
