Which optional features are needed from BT 5? Unfortunately, none of our current BT Combo modules support any of the 3 optional features, but all will be certified under BT 5 (no optional features). We have a new Combo coming in the first portion of Q1'19 that will support 2Mb/s PHY.
Unfortunately, we do not have a combo chip with BLE 5.0 as of now. However you can use BT chip CYW 20719 with BLE 5.0 feature.
For the application you described, you can use Cypress combo chips CYW43438, CYW4343W, CYW43455. More details here: http://www.cypress.com/products/wi-fi-bluetooth-combos
To purchase any chip or module, please contact your local Cypress Sales team or distributor. Or you can check the Cypress Store option on Cypress Website: http://www.cypress.com/cypress-store
