Error: Failed to connect to remote target after update to 4.0.0.2

Question

I updated my gear sport several days ago. After updating to 4.0.0.2, I cannot connect to my watch anymore. Here is my command:

./sdb connect [IP]

It aways said:

error: failed to connect to remote target [IP]

How can I solve this issue?

Answer 1

On the device, go to Settings -> About watch -> Software, from there, tap repeatedly on Software version until Developer Mode is enabled. Then restart your device, and try to connect.

Answer 2

I can confirm the successful steps, it has to be ALL of those steps, and then restart the watch.

Bluetooth: Off, Wifi: On, Debugging: On, Developer Mode: On. Then restart watch.

It will connect after ALL of those settings are in those EXACT states. No other combination worked, not even after a watch restart, additionally my pc is connect to the router via cat5 cable, but the watch is connected over wifi.

Windows 10, Tizen Studio 3.6 (2019-11-22), Galaxy Watch Active 2 (Tizen 4.0.0.7, One UI 1.5)

Answer 3

Here is the solution: turn off BT Restart Watch (OFF and ON) Connect via Wifi with device manager.

Answer 4

I was having the same issue. I finally got my galaxy watch connected. Here are the config/status my watch had: Developer mode:on, Bluetooth:off, Debugging:on, Wifi:connected to my phone's AP, laptop:connected to my phone's AP

After connecting both devices to the same AP, i was able to find and connect to my galaxy watch on tizen studio. So, connecting with a phone's AP worked for me.
