Pi feeding. USB stick dropping offline

[DarkPlatinum]

I am still getting problems. Every 15 minutes or so the DVB-t module disappears from lsusb.

Big indicator your stick is going offline

No supported RTLSDR devices found.

How do I fix this?

Power supply replacement is easiest first test. 2A is required as USB draw of the sticks makes a 500ma-1A drop off.

Or the chip in the USB is failing. Due heat or bad manufacturing

Both of which can occur.

Using a 2.5Amp power supply. People have posted comments saying this worked as a ADS-B reciever.

Using this on you tips does not work:

Stopping the fr24feed.service and the dump1090-mutability.service then running dump1090-mutability gives:

pi@raspberrypi:~ $ dump1090-mutability

Im going to make a new forums post with a better subject so more people can help.

Please stop creating new threads and adding posts to older ones when this all appears based around an issue with your USB stick. And can be solved on one location better than 3.

None of the other software will work until you work out why your stick goes offline. and then needs to be plugged in again to get it back.

If it does that with the lite os. It sure will with the others.

USB claim 6 has also been outlined In the common errors page on the link above. And the various reasons for it and how to solve.

Being.
USB RTL drivers not blacklisted
Dump1090 already running
Crashed dump1090 from stick going offline or similar trying to be restarted.

In the other thread, you can see the system is running in status the 2nd time. The command with --status is for pure Linux with debian instsll.
You are therefore starting it a 2nd time incorrectly when trying to see status.

This causes the error 6 as it's already working as seen by the correct status command.

All of which can also still happen until you stop it from depowering mid use.

You also have lots of access denied commands.

Ensure running everything with SUDO ahead

Ill reboot my pi and do what? I have blacklisted the drivers said in the post, my DVB-T is RTL 2838U, I opened task manager, only 1 dump-1090 is running, my dump website is running, but i cant access it because it just hsa the loading animation and thats it. What are the EXACT things you want me to do?

[Oblivian]

Monitor the status. (Using web page and correct command)

If it continues to drop off. That needs to be fixed first.. All the add-ons rely on a steady working stick and dump1090

Much the same way you don't build a roof then lift it up and add walls and hope for the best. You need a stable feeding foundation first.

The correct command being fr24feed-status yes?
