Dell 7480 bluetooth not detected

in bluetooth options it tells me that no device found
how to intall the driver for bluetooth for my device?

please post the output of

inxi --admin --verbosity=7 --filter --no-host --width

first. use the option “preformatted text” (the 3 ticks) and paste it inside them

well i wonder a liffle bit, can you also post the output of

rfkill

a first step is to check your bios settings about any network/wireless options.
you have a combined wifi/bluetooth hardware-card. they should be recognized both and i wonder that wifi-part is detected while the bluetooth isn’t.
so check the bios-settings if there is something related disabled or set.

p.s.:
also check if there are physical switches or key-combinations to activate/deactivate at the laptop and the “travel/fly-mode”.

Do you know if Bluetooth has ever worked on the device? Some Dell Latitude 7480s were sold with Bluetooth deactivated at the firmware level as required for security reasons by some companies and government agencies. Bluetooth may also have been an optional choice for anyone purchasing online from Dell. You haven’t mentioned if the device is new or had a previous owner, but you may want to check in the BIOS to see if Bluetooth can be activated, or if it is greyed out & not possible to activate.

I found this out via this topic at Dell: ‎Latitude 7480 Bluetooth | DELL Technologies

Sadly, the solution in that case was:

Hey guys,

I’ve made a few inquiries and it turns out that the Bluetooth is disabled at a firmware level. As you mentioned in one your posts it’s aimed at customers in specialized areas where Bluetooth isn’t allowed. I’m afraid that only hardware replacement will resolve this.

If Bluetooth has been deactivated on the motherboard, maybe a USB Bluetooth dongle might be a possible solution?
