I can't set the frequency range

[GarryCZ]

Hi , I can't set the frequency range with one SDR, it still says samples not ok, start: 144.000 kHz, stop: 146.000 kHz, step: 001.000 Hz, bandwidth: 002.048 kHz samples not ok, start: 440.000 kHz, stop: 442.000 kHz, step: 001.000 Hz, bandwidth: 002.048 kHz In the previous version of the scanner it worked perfectly. Here is my config: { "scanner_frequencies_ranges": [ { "device_serial": "auto", "ranges": [ { "start": 144000000, "stop": 146000000, "step": 1000, "sample_rate": 2048000 }, { "start": 440000000, "stop": 442000000, "step": 1000, "sample_rate": 2048000 } ] } ], "devices": { "rtl_sdr": { "ppm_error": 40, "tuner_gain": 10.0, "offset": 0 }, "hack_rf": { "lna_gain": 0, "vga_gain": 0, "offset": 0 } }, "recording": { "max_noise_time_ms": 500, "min_time_ms": 2000, "min_sample_rate": 16000, "max_concurrent_recordings": 10 }, "detection": { "frequency_grouping_size": 10000, "frequency_range_scanning_time_ms": 64, "noise_learning_time_seconds": 30, "noise_detection_margin": 20, "torn_transmission_learning_time_seconds": 60 }, "output": { "logs": "sdr/logs", "file_log_level": "info", "console_log_level": "info" }, "mqtt": { "hostname": "sdr-broker", "port": 1883, "username": "admin", "password": "password" } }

It was a bug, thanks for find it. I hot fixed it and push changes to master with some additional features. Please update. Keep in mind that there is some changes in config.json, please update it.

Hi, after the update I can't connect to SDR.

thank you for your help

Sorry, the previous error is no longer valid I solved it by adding blacklist dvb_usb_rtl28xxu to /etc/modprobe.d/blacklist.conf.

now everything is running perfectly even with multiple bands.

Thank you so much, you're doing a great job
