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. – Biquadrate 4/2, 2019 at 4:55

sure, and I also toggle the debug mode "ON". Are you still using 4.0.0.2 on Gear Sport? – Darondarooge 11/2, 2019 at 9:52

I am not saying about debug mode....i am saying about Developer mode by tapping on software version number – Biquadrate 12/2, 2019 at 4:40

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? – Darondarooge 14/2, 2019 at 2:23

Yes..try with different PC – Biquadrate 14/2, 2019 at 17:28

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. – Darondarooge 15/2, 2019 at 8:21

Enabling the Developer option is the solution – Biquadrate 18/2, 2019 at 13:29

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. – Darondarooge 28/3, 2019 at 6:39

Important is, that you reboot watch after turning off BT nad turning NO wiFi – Tribunate 29/3, 2019 at 8:29

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 – Illfavored 18/5, 2019 at 4:50

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.
