8 years ago Which platform are you running on, Linux or OS X? Do you need to access/connect to the server to trigger the problem, or just leave it advertising 20 mins and it happens?
To debug on Linux platforms, you can hcidump the device which gatt is running on. It might be helpful to see what happened before it become unanswerable.

8 years ago This problem happens on both platform, and i just scan the server without any access/connection after start it. I think hcidump is a good advice and i'll try it for figuring out the problem.
Thank you, @roylee17

8 years ago I can't get anything by hcidump when server disappear. The result of hcidump is below.

I checked the code in device_linux.go is setting advertise mode as "LE General Discoverable Mode", so it shouldn't disappear after starting for a while, is there anyone can figure something out by the above result of hcidump?
Thanks so much.
I can scan and get the server after I build and run the sample server, but after running up the server about 20 minutes, i can not get the server anymore. (Scan by LightBlue in iPhone and hcitool in Linux) If i shut down current unanswerable server and restart it, it appear immediately again. Is there any hint about this problem?
Thanks
