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?

Turn on Developer mode by tapping several time on the software version number. — Iqbal hossain, Feb 04 '19 at 04:55
sure, and I also toggle the debug mode "ON". Are you still using 4.0.0.2 on Gear Sport? — James Fu, Feb 11 '19 at 09:52
I am not saying about debug mode....i am saying about Developer mode by tapping on software version number — Iqbal hossain, Feb 12 '19 at 04:40
Yes, I indeed tapping on software version number and see the developer option in the settings. Are you sure you are using Gear sport 4.0.0.2, and you can connect to your watch? — James Fu, Feb 14 '19 at 02:23
It works when I change to the Windows PC. After, I use the Mac and it can connect to my Gear Sport again. It is so weird, and I don't why it happened. — James Fu, Feb 15 '19 at 08:21

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.

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)

It does not work for me. I try to use my phone as a hotspot and connect both my phone and computer to it. Then, it works again. – James Fu Mar 28 '19 at 06:39
Important is, that you reboot watch after turning off BT nad turning NO wiFi – Uroš Krašovic Mar 29 '19 at 08:29

Restarting the watch after enabling developer mode worked. I can now ping the watch, as well as connect in the device manager. I have a Frontier S3, running Tizen 4.0.0.2 – Jarryd May 18 '19 at 04:50

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.

You need to accept debugging rha fingerprint from your watch. That is, you need to check and press the tick on the watch.
