I was facing this error:
$ sudo python auto_rx.py 2021-07-26 08:50:15,471 INFO:Reading configuration file… 2021-07-26 08:50:15,472 WARNING:Config - Web Password not set, disabling web control 2021-07-26 08:50:15,949 INFO:RTLSDR - Attempting to reset: Bus: 1 Device: 9 2021-07-26 08:50:18,712 INFO:RTLSDR - Attempting to reset: Bus: 1 Device: 9 2021-07-26 08:50:21,457 INFO:RTLSDR - Attempting to reset: Bus: 1 Device: 9 2021-07-26 08:50:24,219 INFO:RTLSDR - Attempting to reset: Bus: 1 Device: 9 2021-07-26 08:50:26,993 INFO:RTLSDR - Attempting to reset: Bus: 1 Device: 9 2021-07-26 08:50:29,430 ERROR:RTLSDR - RTLSDR with serial #0 was not recovered after 5 reset attempts. 2021-07-26 08:50:29,430 WARNING:Config - SDR #0 invalid. 2021-07-26 08:50:29,430 ERROR:Config - No working SDRs! Cannot run… 2021-07-26 08:50:29,430 CRITICAL:Error in configuration file! Exiting…
Note I was using “sudo” to run the auto_rx.py command, because normal user was receiving permission error. Then searching in the Internet I didn’t find a solution, but started to suspect it could be related to the permission.
Then I downloaded the udev rule: https://raw.githubusercontent.com/osmocom/rtl-sdr/master/rtl-sdr.rules and copied it:
$ sudo mv rtl-sdr.rules /etc/udev/rules.d/70-rtl-sdr.rules
And restarted the udev:
$ sudo udevadm trigger
Then the reset error disappeared but other error happened:
$ python auto_rx.py

2021-07-26 09:01:54,537 CRITICAL:Binary mp3h1mod does not exist - did you run build.sh?
Then I moved to depmod and compiled the mp3h1mod:
$ cd ../demod/mod/
$ vi Makefile:
…
PROGRAMS := rs41mod dfm09mod rs92mod lms6mod lms6Xmod meisei100mod m10mod mXXmod imet54mod mp3h1mod
…
mp3h1mod: mp3h1mod.o demod_mod.o
…
$ cd ../..
$ make
$ cp demod/mod/mp3h1mod auto_rx/
Then everything worked as expected:
$ python auto_rx.py
