7. Operation
Operation through SSH
connect via SSH - adjust the port number and possibly also the user scanner
ssh -p 9001 scanner@hayguen.hopto.org
in case you are already connected to the host - as different user
sudo su -l scanner
start the scanner (as scan user)
startBgScanLoop.sh
stop the scanner (as scan user)
stopBgScanLoop.sh
check results while scanning - before having uploaded (as scan user)
scanEvalFMcmpPS.sh scanEvalFMcmpPI.sh scanEvalDABens.sh scanEvalDABensTii.sh scanEvalDABprogs.sh
upload all results (as scan user)
stopBgScanLoop.sh wait prepareScanResultsForUpload.sh all uploadScanResults.sh
probably, you want to edit the upload comment FMLIST_UP_COMMENT - before uploading (as scan user)
cd ~/.config/fmlist_scan nano fmscan.inc
and after the upload, you might want to restart the scanner (as scan user)
startBgScanLoop.sh
and probably also restart monitoring
monitorBgScanLoop.sh
Operation through Webserver
all operations can be done through the webserver
Buzzer status tones
The scanner reports its status primarily via the piezo-buzzer. The detection of Broadcast-FM and DAB stations is reported with tone sequences on each scan. See configuration entry FMLIST_SCAN_PWM_FEEDBACK
| Event | Tone sequence |
|---|---|
| Welcome at startup | short short short long short |
| FM success (at least 1 transmitter) | short short, short |
| FM failure | short short, long |
| DAB success (at least 1 station) | short long, short |
| DAB failure | short long, long |
| Write error for result | 3 x (long long long) |
In addition to these operating results, there are other tone sequences to sign
- Start the scanner
- Error status, e.g. no RTL dongle found
- Scan results saved
Test / listen with scanToneFeedback.sh or the webserver
The individual LED colors have no dedicated meaning. They are switched over for each recognized station. There is no changeover if the next station is detected within/below one second - in order to limit the changes.
