You need to do two things:
- Serialize both dongles with different serial numbers
- Configure piaware with dongle serial numbers, so that dump1090 and dump978 use their respective dongles
Assuming that you are using piaware SD Card image, follow instructions below:
STEP-1: Serialize both dongles (CLICK HERE)
If you want to recieve both ES1090 and UAT978, then two dongles are required, one for 1090 and other for 978. In this case you will have to serialize dongles so that correct dongle+antenna sets are used by dump1090-fa and dump978-fa.
For 1090 Mhz dongle: use 8-digit serial # 00001090
For 978 Mhz dongle : use 8-digit serial # 00000978
Note: You can use any other serial numbers if you want, but do not use single digit serial numbers (0 to 9) or (01 to 09), as these may conflict with device numbers. Use at least two digit numbers like 21 or 93 etc)
STEP-2: Configure Piaware
sudo piaware-config uat-receiver-type sdr
sudo piaware-config rtlsdr-device-index 00001090
sudo piaware-config uat-sdr-device driver=rtlsdr,serial=00000978
Reboot Pi to implement configuration settings
sudo reboot
STEP-3: Check Status
sudo systemctl status piaware
sudo systemctl status dump1090-fa
sudo systemctl status dump978-fa
