No, it doesn't do anything when I plug it in.

then its an issue with your phone, not andruav. what phone are you using?

from andruav_android_app.

I am using a Telstra "Signature 2" made by LG, and I also tried on an Oppo A73 with the same issue. USB debugging is enabled and I tried on both charging and MTP mode with no luck.

do you have another usb serial device you can try? if it doesnt ask you to open it with andruav when you plug it in then your phone does not support USB SERIAL. you could get a bluetooth serial adapter like a HC-06 I found them to be more reliable than the usb connection.

from what i can find the phone doesnt support USB OTG.

Is your phone OTG supported?

from andruav_android_app.

Hmm, I will try the Bluetooth module. The app says it supports USB OTG but I don't have an adapter to test if it actually works. Thank you for your help!

You may want to give this a try to see it establish a connection

By the way, what flight controller firmware are you using? I think this app only verified with Arducopter firmware with mavlink protocol.

Or you may have accidentally click always associate the USB device to another app before.

Or your phone is USB OTG supported but the connector adapter does not complice to USB OTG. Are you connecting directly or through a USB adapter. Can you post a picture?

I was using Arduplane, I tried it with Arducopter but it still didn't work. There was never any popup to open the USB device.

I am using a small USB-C OTG adapter which was plugged into the FCB. I know the adapter works when plugged into a phone for normal OTG uses. But I tried plugging it into the FCB and connecting to my laptop through that, and it didn't even power on, so maybe that's the problem. I think I will try the Bluetooth module, and then I won't have to deal with dodgy micro-USB connections that only work at a specific angle 😛.

From the same family, should work too.

you have to plug the OTG adapter into the phone. It only goes in the server which is the phone. If that doesn't work, you may need to jiggle it which was my problem (connection not reliable between OTG adapter and usb cable.
