I updated for the first time in over 2 years and can't get pingEFB support to work. The first boot linked /dev/ping to /dev/bus/usb/001/004 which matches the FTDI device on lsusb. However, the web interface shows Disconnected for the ping device. Here is the failure in the log.

2021/05/07 17:22:46 Using /dev/ping for Ping
2021/05/07 17:22:46 Error opening serial port: inappropriate ioctl for device

dmesg showed the device was assigned /dev/ttyUSB0. I deleted the symlink for /dev/ping and replaced it with

sudo ln -s /dev/ttyUSB0 /dev/ping

The UI shows connected in green , but no ADS-B traffic seems to flow. Upon reboot, when I reenable ping support, the UI shows disconnected. The symlink for /dev/ping is now linked to /dev/gpiochip3. This is the failure that shows up in the log with that symlink.

So manually symlinking /dev/ttyUSB0 to /dev/ping is the only way I can get the pingEFB device to show connected in the web UI , but no traffic is flowing to the web UI or the Avare EFB. I have confirmed that my pingEFB device does not need to have the firmware update by uAvionix applied.

Update: I moved my pingEFB away from a large monitor and data started flowing. The issue of the symlink for /dev/ping still remains. The web UI shows connected when I symlink /dev/ttyUSB0 to /dev/ping, but does not survive a reboot or manually disconnecting and reconnecting the pingEFB USB cable at any time.

As a follow-up, it seems stratux is only processing FIS-B data services and TIS-B traffic on UAT. No direct 978 traffic (bad weather, no surprise there) but no 1090 traffic either -- that's a surprise. The green light on the pingEFB device only blinks about 4 or 5 times at first power-up, but only the red light blinks after that. It has been a few years since I last used this, so I don't recall which color is linked to which band. I've toggled the 978 and 1090 hardware switches on (even though I don't have an SDR) and as expected that did not fix the problem. I'm only seeing FIS-B and TIS-B data coming through.

Here's the log snippet showing no ES traffic. Only UAT targets:

Update: I received direct 978 traffic today as well as a screenful of TIS-B traffic and METARS. Still no 1090 traffic.

Update: I updated to eu027. PingEFB worked out of the box, but did not survive a reboot. I still need to edit the symlink after every boot in order to get the pingEFB to show connected in the web UI. I also have 0 packets on the 1090 side and no 1090 traffic.
