Which BLE version in DA14581?

I have DA14581 functional spec that indicates that this chip supports BLE v4.1. A newer version of the spec (and the webpage summary) for this part indicates BLE v4.2:

"The DA14581 supports a flexible memory architecture for storing Bluetooth profiles and custom application code, which can be updated over the air (OTA). ...The transceiver interfaces directly to the antenna and is fully compliant with the Bluetooth 4.2 standard."

Which BLE version is actually supported? Were there changes made to the part to add BLE v4.2 support (e.g., ROM code)? How would we add 4.2 support to our application?

Hi JamesHiebert,

Hi JamesHiebert,

The DA14580/1/2/3 is designed to support BLE 4.0 and not a 4.1 or 4.2.  However, it is compliant with BLE 4.1 and BLE 4.2 but it doesn’t support the optional features of 4.1 and 4.2, like dual role.

Thanks, PM_Dialog
