I can see the inverter when I do hcitool scan, but can't get it to connect.

Commandline Args: -cfg/usr/local/bin/sbfspot.3/SBFspot_1.cfg -v -finq -nocsv
Reading config '/usr/local/bin/sbfspot.3/SBFspot_1.cfg'

Try another Bluetooth dongle for your RPi - This helps in most cases. More info here
This has no impact on your connection, but have a look at the timezone in the config file. Sunrise and sunset have weird values.

What is strange is that it connected fine with this Bluetooth dongle using the last version, 301. Had a problem with the Pi and had to reinstall the operating software and the SBFspot.

hej cabledave,

-A- are your certain about the BT address for most SMA inverters it starts with "00:80:25:xx" and NOT "00:08:25:xx"
please control

-B- if there are further problems
-B.1- can you execute sbfspot including, in your command line, the debug options -d5 -v5
-B.2- redirect the output to file

command -cfg/usr/local/bin/sbfspot.3/SBFspot_1.cfg -d5 -v5 -finq -nocsv 1>>yourlog-ou.txt 2>>yourlog-er.txt

and send the files via private mail to me or sbf

kind regards wim

Hi Willie,

Excellent catch! That was exactly what it was. Corrected the BT address and works perfectly. Thanks for your help. Very much appreciated.

dear cabledav, the forum is used to assist in solving problems

for that reason,
  • can you do us the favour and execute SBFspot with the faulty condition == wrong destination addreess
    AND with the debug options that i did mention above
command -cfg/usr/local/bin/sbfspot.3/SBFspot_1.cfg -d5 -v5 -finq -nocsv 1>>yourlog-ou.txt 2>>yourlog-er.txt
and send the log files via private mail

  • in your first information - one reads that sbfspot received a correct "connected" reply
  • followed by failing communications
  • your log files might help to identify the source of the "connected" status
thanks for your cooperation wim
