Unable to establish a connection: NotFoundError.....

[goofy2k]

Hi, I want to test Improv on a ESP32 NodeMCU board. I added the component to the firmware. Selected 'none' for authorization. The code compiles OK and the logs show that the BLE serve is up. I want to test using the Connect device to Wi-Fi button on your imrov-wifi.com site. I access the site on my mobile phone with BT on.

I see an icon that measures signal strength from my ESP32 device. When I press the button to connect a popup apperears, telling:

An error ocurred. Unable to establish a connection: NotFoundError: No Services matching UUID 00467768-6228-2272-4663-277478268000 found in Device.

As there are no other required settings involved, I would expect that trying to connect from any device and any site (including yours) would be OK.

Am I wrong?
Do you have any suggestions on how to proceed?

After enabling web bluetooth in the browser

(see: https://reelyactive.github.io/pareto-anywhere/enable-web-bluetooth-scanning/ ) the error message remains unchanged.

I'm assuming this is Android.

We haven't been able to get WebBluetooth on Android working reliably yet.

OK, thanks ! If it isn't Chrome on Android, where should I use it preferably? Op za 26 jun. 2021 00:24 schreef Paulus Schoutsen ***@***.***

@balloob, to prevent misunderstandings: I used Chrome on my Android mobile. So I use the JS solution (SDK-js) . For my own understanding: is it right that iffff all things worked like you have intended, would it be possible when I did not run my own web page running the code but any page? Such as now, that I used the button on your page in the documentation?

@balloob Curious if there's been any progress getting Improv to play nicely with Android WebBluetooth?

Nope

Can you tell me which component you integrated into your firmware? I already integrated https://github.com/[improv-wifi/sdk-cpp](https://github.com/improv-wifi/sdk-cpp) for serial communication and this works fine. But now i want to use esp-web-tools via BLE

Hi @tobiasfaust, Unfortunately I can't remember. It is 3 years ago and I haven't done anything since then with bluethooth. I looked in my repos and see an old project with NimBLE. But I don't see a reference to activities with improv. In my Faust(!)-Synth-MIDIBLE I see an esp-nimble-cpp component. I took that from https://github.com/h2zero/esp-nimble-cpp/release/tag/v1.4.1 Goodluck with your project! Op za 16 nov 2024 12:15 schreef tobiasfaust ***@***.***>:
