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

Are you sure that's referring to the BT protocol version - not some Linux utility version?

For BLE, you need a BT protocol version of at least 4, and your hardware must have BLE support.

To use BLE 5 features, your Host will need BLE 5 protocol support in both hardware and software.

BLE 5 is backwards-compatible with BLE 4.
