On Raspberry PI 4B, I was having trouble trying to start UAT using Nooelec NESDR Nano 3.
Dump1090-fa start with no issues, but the enabled dump978-fa.service fail with “Error -6” (device in use).
During the initial configuration, as advised, I did the following:
sudo piaware-config uat-sdr-device driver=rtlsdr,serial=00000978
However, UAT (dump978-fa) fail to start.
Using sudo rtl_eeprom -d1, I find out that the ‘real’ factory serial number was stx:978:0 and not the expected default 00000978.
..... Current configuration: __________________________________________ Vendor ID: 0x0bda Product ID: 0x2838 Manufacturer: Nooelec Product: NESDR Nano 3 Serial number: stx:978:0 Serial number enabled: yes IR endpoint enabled: no Remote wakeup enabled: no
Two methods can fix the issue
- Edit the factory serial on the device (using rtl_eeprom)
- Change the serial on the config command:
sudo piaware-config uat-sdr-device driver=rtlsdr,serial=stx:978:0
After the fix, all services running as expected.
