BLE 5 vs BLE4 programming

[terrence]

I know the many differences coming in bt5. Will the programming concepts be the same in the upcoming 5 version? IF my code is working with ble4.1 will it automatically work with bt5 boards?

Hi Terrence,

you are correct that Bluetooth 5 introduced several new features like High-Throughput(2Mbit/s) and Long Range. In order to use these BLE 5 specific features, both sides of the link(both devices) must support BLE 5. The rest of the Bluetooth Core Specification has not been changed to ensure interoperability with the older BLE versions.

So yes, BLE 4.1 and BLE 5 devices will still be inter-operable the same way as BLE 4.1 and BLE 4.2 devices are inter-operable.

Best regards

Bjørn
