BT 5.1 on CYW4343?

[JoHe_3380801]

Recently a couple of documents surfaced both on Cypress's site and Murata's, claiming the CYW4343W supports BT5.1.  The datasheet still only claims support up to BT 4.1.  Does anyone know what features of BT5/5.1 the CYW4343W actually supports, if any?  Or is this a copy n' paste error that got out of control? 

Product brief referencing BT 5.1:

Murata module page also claiming BT 5.1 (type 1DX module):

And actual Murata datasheet for the 1DX module, with CYW4343W, claiming BT 5.1:

Thanks!

Hi JoHe_3380801​,

CYW4343W supports BT 5.1. However, no optional features of BT5.0 are supported.

The CYW4343W datasheet on Cypress website is not updated to BT5.1, I will initiate the process to update the datasheet internally.

You can check QDID 134532 for the same.
