NRF CONNECT

[Berkay Dudu]

Hello,

Can the NRF52840 module connect with normal Bluetooth modules (such as HC05, HC06)? Is it necessary for the normal Bluetooth module to have BLE support? If so, can the BLE versions be different?

BLE and BT classic only modules don't see each other and thus cannot communicate (or connect).

BLE was added in  the bluetooth 4.0 standard, everything above should be able to talk to an NRF52840 module when programmed correctly.

That is, two modules with BLE support can connect and communicate even if their versions are different. For example, a device with BLE version 4.2 can communicate with a device with BLE version 5.0, correct?

Yes.
