Bluetooth Versioning

[TigerD]

Hi,

I have some nRF52840 DK boards and want to develop a system with 5.0 BLE.

But my linux box host has older version:

Bluetooth: Core ver 2.22

My first question is this is Bluetooth 2.22, and the BLE5.0 is Bluetooth: Core ver 5.0? So we are using Core version as Bluetooth Version.

Is possible for Core ver 2.22 program (central) to scan Core version 5.0 advertisements? I believe it will not work. Let me ask in another way: Is it possible for nRF52840 to be programmed so that it can be scanned by Bluetooth 2.22 device?

Thank you,

David

That "Bluetooth: Core" version number tells you...

NOTHING AT ALL.

In fact, my Linux box has the same output in dmesg:

[589393.748891] usb 4-3: Product: BCM20702A0
[589393.748895] usb 4-3: Manufacturer: Broadcom Corp

[589394.223698] Bluetooth: hci0: BCM20702A1 (001.002.014) build 000

But this is with a connected BT4.0 USB stick, which can talk to NRF devices via bluetooth low energy.

We would need to know what hardware is actually in your Linux box.
