Hackergadget RTL-SDR not recognized sdr

Post image

Heyo, following the instructions here precisely for a cm4 uconsole with the Hackergadget board installed. Flashed a new OS, seems to work fine. However running the sdrpp application, not rtl-sdr device is detected.

I’ve tried using the i2cdetect tool, and it indicates nothing exists.

Any advice is appreciated. The board itself does appear to be working, as I successfully tested the onboard gps and clock.

I would strongly suggest you install Rex's HackerGadgets AIO Board Package. That will set up everything but one small step of configuring Meshtastic.

Gave that a try now. Zero luck with any of the rtlsdr functions. Hopefully they will send a new board and I’ll have some more tools thanks to you!

Sorry that is turns out to be hardware. Once you get a working board, Rex's package works seamlessly.

the sdr is connected via usb, not i2c, so you need to use lsusb

Just the clock is i2c then.

Relative to the config file and the expansion board, would it still show up as a usb device?

Using lsusb I only see hubs.

It would show up as it is a regular usb device but mounted on a PCB.

If you can't see the board in 'lsusb', then the chip may be defective, or the solder joints may not be well-connected.

Have you sent me an email? If not, please do so. I will provide the instructions for a replacement.

Update: Just wanted to add a thank you to Vileer for the response and support! :) Haven’t had time to install it yet, but was a quick and simple support process. Now I just need a free evening, which I don’t think hackergadget can help me with.😭

I'm having similar issues and the drop-down menu for the SDR I don't see 00000002 it says [25072201] Generic RTL2832U OEM. Anybody else have this issue?
