OTA process: Tools/b2qt/adb connect <IP> : unable to connect

[miguelorenes]

I have an RPI 3 Qt device. I have Qt Creator configure, ready, able to compile and deploy for on the RPi3 any Qt example also my applications.

Now, I am trying to follow the guide: https://blog.qt.io/blog/2016/06/28/over-the-air-updates-part-2-device-integration-api-and-creating-updates/ and basically on the first step I have a problem: I cannot find the way to connect to the device so:

osboxes@osboxes:~/Qt/Tools/ota/dracut$ ./generate-initramfs
Using adb from /home/osboxes/Qt/Tools/b2qt/adb
error: device not found

I am trying to connect to the device via adb by IP, but I am getting an error:

osboxes@osboxes:~/Qt/Tools/ota/dracut$ adb connect 172.16.2.69
unable to connect to 172.16.2.69:5555

The device is accesible, as I can connect via ssh as well as deploy apps from Qt Creator.

Any thought?

Answering myself...
I am leaving the idea to make the connection because of OTA is not supported on RPI 3 according with:
http://doc.qt.io/QtForDeviceCreation/qtee-supported-platforms.html -> Supported Features on Target Devices section.
