Anybody know how to fix this?

hi @John_Doe
This is strange behavior, The example should work fine.
Are you connected to the same wifi network?
Have you also changed the ip address to your local ip address? You also need to start the server on the same port.

Hi! I have exactly the same issue with just ble_scan example on few devices.

But few days ago it worked fine, I’m upgraded to current Zerynth version and now its crashing after few seconds. I’m tried to use previous version of Zerynth studio but the same issues.
