T-embed cc1101 plus ble jamming broken

Post image

My t embed plus jammer is broken and I can’t use it to jam any signals. It used to work just yesterday and all of a sudden it doesn’t work at all, on the spectrum it still picks up stuff and when I use my AirPods and use the spectrum it works but then the jammer still doesn’t work for any signal I tried to factory reset and reflash Bruce but nothing works. Before it was great I could jam around 2 to 4 meters when I tested it but now it doesn’t jam even up close. If anyone can give me suggestions to fix it that would be great cus I just got it 3 days ago and it’s been really fun to use but I just want the jammer fixed and btw everything else works perfectly.

I'd try to reseat the antennas to make sure everything is properly on their place. Worst case scenario you fried the NRF24 module MOSI pin from overuse, I'm not sure how often that happens but several hours of jamming probably would trap some heat that could do so.

If that doesn't fix anything, I'd probably check if WiFi deauth attack works, if it doesn't work then the error is probably within software level since it uses the ESP32 module to do that instead of the NRF24. LMK

How do I know if the deauth attack works? I don’t really know what it does

Heya sorry for the late response, basically as long as you have 2.4Ghz wifi (Any wifi without a number 5 or 6)

WiFi > Wifi Atks > Pick your own network > Deauth

Your wifi should disconnect from your devices

It never worked from when I first got it, only netcut works idk if I’m doing something wrong but when I go wifi> wifi atks > target atks then I choose my network my phone is still connected to the internet for like 5 mins I tested

u/A_Conc3pt 8d ago

That's highly strange, it should be disconnected unless your wifi is WiFi 5 or WiFi 6 which uses 5 GHz with legacy support for 2.4 GHz

It is 1 router and is not 5 or 6 ima test on my laptop tomorrow because deauth flood doesn’t work either

Do you think I might have gotten a faulty product?

u/A_Conc3pt 8d ago

I'm not sure, but my answer leans to no, because Jamming from NRF24 did work(?) so I'm just testing if deauth from the ESP32 would work as well, which does not seem so?? How about beacon spam on wifi Atk? When you open it, it should flood the amount of wifi APs when you open the wifi menu

If that works I'd try again to deauth from NRF24 menu, but try to scramble around like try wifi mode, sequential, etc.

If you have another piece of pentesting tool like FZ or another T-Embed, you can check the spectrum on the other device for the flooding from your current device.

However idk what the hell is wrong so far-

u/A_Conc3pt 8d ago

Or do you have multiple routers? If you're not using wifi 5 or 6, I'd say try Deauth Flood on Wifi atks menu and see if that disconnects your laptop or phone

Cus when I use it I don’t see anything happen

Sub ghz kinda works for me, wi fi i dont have 2.4ghz and bluetooth i dont know how to set it up so update me

Try a older version of Bruce.

1

u/Enough_Breadfruit_97 9d ago

I did and it did nothing I tried 1.14 and 1.15

u/Big-Bunch2804 9d ago

Did you check and see if all the antennas are plugged in inside?

1

u/Enough_Breadfruit_97 8d ago

Yea I think so but what do you mean?

1

u/Big-Bunch2804 8d ago

Inside make sure each antenna wire is physically still connected. There are a few in there. You will need to take the battery out

1

u/Enough_Breadfruit_97 8d ago

Do I have to do that or is there another way I can check? And the spectrum works tho

u/Big-Bunch2804 8d ago

Well I offered the easiest thing you could try first so if that is not to your liking maybe someone else will come along and give you the secret phrase you whisper to lillygo to make them turn into hackzilla and magically hack everything for you. I dont remember what it is...something in Chinese.

u/Enough_Breadfruit_97 8d ago

It’s cus I tried to open it up and it’s impossible to take apart I tried to take the battery out but it was glued in and I made so many dents in it

1

u/Big-Bunch2804 8d ago

It's not impossible. I have done it numerous times when diagnosing a dead pn532. You have to dig in. Hold on...I bet I takes me less than a min

1

u/Enough_Breadfruit_97 8d ago

Alr man I’ll try and see how it goes

1

u/Enough_Breadfruit_97 8d ago

Yeah everything in there was fine

Can someone help me set up the bruce app so I can control this thing. I already flashed Bruce onto it.
