rtlsdr: error opening the RTLSDR device: Device or resource busy

[ea5xq]

Hi

I have installed rbfeeder and works fine. I added fr24feed and adbsexchange and only if teh Raspberry Pi (3b+) reboot rbfeeder faces problems to access the SDR (radarbox original), I have to stop rbfeed, fr24 and adsbsexchange, switch off/on the SDR and starts only rbfeeder and thereafter the rest. It seems that a process is taking the control of the device before Rbfeeder. How could I control it? thanks

I would suggest that RB feeder is trying to uses its internal 1090 but as the stick is already in use with the FR24 1090 is cannot connect.  Can you post your ini file with your details redacted

Thanks

here is the rbfeeder.ini

[client]
network_mode=false
log_file=/var/log/rbfeeder.log

sn=EXTRPI657091

#device=00000010

lat=39.917340000000003

lon=-0.0071050000000000002

alt=13

[network]
mode=beast
external_port=30005
external_host=127.0.0.1

[mlat]
autostart_mlat=true
#mlat_cmd=/usr/bin/python3.9 /usr/bin/mlat-client

[dump978]
dump978_enabled=false

And the fr24feed.ini

receiver="avr-tcp"
host="127.0.0.1:30002"
bs="no"
raw="no"
mlat="yes"
mlat-without-gps="yes"

Thanks

Under Client, change network_mode=false to network_mode=true

Had a look at EXTRPI657091 and you are showing aircraft

Thanks!, it worked like a charm, now I am able to feed three aggregators

Hi!   I'm having the same problem.  I've changed the .ini under client to true (from false).
This didn't change anything and I'm still offline.  My station is EXTRPI025073

Help, please!
