:pushpin:Question Description

Have you searched the community for related issues?

  • No similar issues found. Or at least, no one asked for a solution, or maybe I used the wrong keywords to search on this forum

Please describe the problem you’ve encountered in detail:

  • Description:
    The Wi-Fi is working fine, the Bluetooth is marked as enabled, there are no errors on enabling/disabling the Bluetooth connectivity (either using the settings’ toggle or using the quick settings’ toggle). But : no device is detected (except a payment terminal in a shop near me), the SP4 is not detected either on another device. Typically, my phone and my laptop are invisible to each other.
    Before you ask, yes, my phone’s Bluetooth is working well, I’m actively connected to a watch and I have no issue connecting to other Bluetooth devices from it.
    It’s just the SP4’s Bluetooth that doesn’t work well. I thought about a “driver” issue, so I did some research. As the device combines Wi-Fi and Bluetooth, the driver is, to my understanding, the same. And regarding lsusb and lspci values in chrome://system/, the device registered in the system is effectively a Marvell card.
    I’ve searched this forum for a solution, I’ve searched some Linux’ forums for a solution, all say that I must enable the right driver, which looks to be already done as the good one is detected on chrome://system/ and the Wi-FI (on the same component) is working fine.

Fydeos is Chromium OS. The Bluetooth on chromium os can only detect mouse, keyboard and speaker, not phones or other computers.

Indeed that’s what I found on ChromeOS/ChromiumOS documentation about Bluetooth, but I hoped that it was only a material limit, not a software limit, so FydeOS For You for SP4 could handle BT connection with any kind of device just like Windows/Linux does. But as long as it is a software limitation, I think there’s no way to go further and solve it. That’s sad…

Anyway, thanks for your answer :slightly_smiling_face:
