connect to Web Bluetooth

[luca brandt]

Hello,

I'm trying to connect a bluetooth device (peripheral) with Web Bluetooth (central). I send an addvertising packet and I can see the device in Web Bluetooth but I fail to connect to it. My code looks like this: (MicroPython)

ble.gap_advertise(interval_us=100, adv_data=bytearray(b'\x02\x01\x06\x06\x08\x45\x53\x50\x33\x32\x11\x07\x26\x6c\x34\x7f\xb2\x38\x61\x82\xbe\x4d\x1d\x64\xf1\xf7\x93\x16\x02\x19\x80'),resp_data=None, connectable=True)

Thanks in advance!

What testing / investigation / debugging have you done to find what's going wrong ?

Do you get any error messages?

Do you have tools on the Central & Peripheral to see what's happening?

What are you using as the Central?

What device is the Peripheral ?

Have you had any success connecting to other peripherals?

Have you had any success in establishing a "conventional" BLE connection in MicroPython ?

On my Bluetooth enabled web browser (with JavaScript) I'm requesting a bluetooth device and  try to connect to it. I don't get an error message but it just doesn't connect. (Code: server = await device.gatt.connect()) The Code stops at that line. 

The JavaScript code worked with another bluetooth peripheral. (RN4678) I checked. I exchanged the device name and the service using the filter option. The service I want to access is in the payload. And with the App nRF Connect it works perfectly. I can connect to the peripheral and read and write data.

So it sounds like the problem is in your browser setup - which is really beyond the scope of this forum.

You need to look into the diagnostic capabilities of your browser and the platform it's running on to see what's going on.

Compare & contrast the working and non-working cases.

You didn't answer.

Does it have any diagnostic capabilities to help you?
