Hello, I am quite new at this thing... I was asked by my organisation to bootstrap to take care of their drone, the drone in question has a flight stack of M0018 gen 1 I belive and some L9N stuff etc etc...
The drone boots up and gets into disarmed mode (blue light flashing with around 10Hz) and I cant find the combination to arm it. In addition, the module creates its own wifi, yet I cannot connect to it because of the previous owners having given us the drones without the password (tried internet name plus the usual 1234567890)...
I am still trying to figure out what the next step would be... 
Is there a hardware reset button to hopefully reset the drone? (Maybe the pin 7 in J2?)
What should be the combination to arm the drone? I was told throttle to the down-right, doesnt seem to work...

Thanks in advance

@Κωνσταντίνος-Κλέων-Χριστόπουλος No hardware reset but you can easily load the latest PX4 release through QGroundControl after downloading voxl_SDK_1.2.0.tar.gz from our downloads page (downloads.modalai.com) and finding the FCv1 .px4 file in the flight-core directory

@tom Thanks for the answer! I still havent managed to connect to QGroundControl in windows via usb, I did try to set a new serial connection, but the thing still doesnt work... DO you think there is a higher chance of QGroundControl detecting the drone in ubuntu?

@Κωνσταντίνος-Κλέων-Χριστόπουλος We only really use Ubuntu here so that would be a good thing to try.

I missed that you said the drone was in WiFi AP mode

You can SSH onto the drone by connecting to that wifi (password 1234567890) and running:

```
ssh root@192.168.8.1
```

the ssh password is `oelinux123`

@tom No the problem is that the password is changed because the default password of 1234567890 doesn't work.... I did try with ubuntu to detect it via usb, but it still doesnt seem to work... Any ideas on how to proceed?

@Κωνσταντίνος-Κλέων-Χριστόπουλος When connected to an ubuntu machine, what do you see with `lsusb`

@Κωνσταντίνος-Κλέων-Χριστόπουλος It doesn't appear that VOXL is being detected at all. Can you share a photo of how you have it connected to your host machine?

@tom Yes of course! The drone came with the hardware I am about to show you, essentialy its just a direct connection to the board with an usb, I am gonna attach a google drive link with also a video describing the connection: https://drive.google.com/drive/folders/1_8Ibo0LjGREFCFQK3HhQeKrglHFpdbap?usp=sharing

@Κωνσταντίνος-Κλέων-Χριστόπουλος You need to have the 4-pin JST to USB cable plugged into the blue connector if you want to access QGC over USB

@tom And I can't see from the video whether you have a VOXL on board or not?

## Reply by Κωνσταντίνος-Κλέων Χριστόπουλος · 2024-05-03 19:18:48 UTC (in reply to tom)

@tom No there doesnt seem to be any voxl on board, the complete stack as far as I am aware of is a M0018 flight core, a modelai power module (apm lite?)m a huzzah esp32 and a L9R

@Κωνσταντίνος-Κλέων-Χριστόπουλος In that case we can't help you with SSH or WiFi, that's not our hardware
