Thanks for contacting Cypress Technical Support.
BT stack of CYBT-343026 is already included in the ROM code.
However you can run BT stack on any other host like any micro controller/Linux/Android and can send directly HCI commands to CYBT-343026 device via HCI UART.
HCI UART pin details are given in the datasheet here: https://www.cypress.com/documentation/datasheets/cybt-343026-01-ez-bt-wiced-module . However you may need to program it initially with firmware / patches .
Programming options are detailed here: https://community.cypress.com/docs/DOC-14990

Thanks & Regards,
