Commented Unassigned: segfault when SMA is not ready after sun up [138]

On rather dark days right after sun up, so SBFspot V3.1.2 reports:
SBFspot V3.1.2
Yet another tool to read power production of SMA solar inverters

Right after that the application gets a segfault and exits with exit code 139. This goes on until a bluetooth connection succeeds. At the end of the day till sun down the bluetooth connection succeeds and there is no problem.
Comments: Hi, Today I just happen to see a segmentation fault entry in /var/mail/pi. /home/pi/scripts/pvoutput.sh: Zeile 6: 5773 Speicherzugriffsfehler /usr/local/bin/sbfspot.3/SBFspot -v -finq After checking the time stamps I saw that this happens only between 5 am (cronjob starts) and the last cronjob before getting power values from the inverter. After sunset, even with zero power readings, sbfspot runs without any further errors until next morning. System is a rasbian jessie, completely reinstalled two weeks ago. Is that a known issue? Kind regards
