For CYW89071 and CYW20713, have Cypress keep supporting by updating FW or HCD? For BT host, it needs to modify accordingly. But if Cypress doesn't intend to fix or do any update, host will not be able to modify as well.
The CYW89071 and CYW20713 are not supported within the broad market or here on the Cypress IoT community.
For development tool and technical support, please work with the local Cypress/Distribution team that enabled you as an early adopter on this platform.
