Operating Modes
EZ-Serial
EZ-Serial is a firmware platform built on top of the Vela IF820 Module, providing an easy-to-use method for accessing the most common hardware and communication features for dual-mode Bluetooth® applications. It uses a UART-based API for use with an external host MCU. Ezurio provides open-source Python host samples to test common use cases.
EZ-Serial supports cable replacement capability for both Bluetooth® Classic and Low Energy.

HCI
The Vela IF820 includes a HCI UART interface that can be used with an external host. The UART physical interface is a standard, 4-wire interface (RX, TX, RTS, and CTS) with adjustable baud rates from 115200 bps to 3 Mbps.
For more information see HCI Development
Custom Firmware Development
The Vela IF820 is fully supported by the Infineon ModusToolbox™. ModusToolbox™ releases provide the latest ROM patches, drivers, and sample applications allowing customized applications using the CYW20820 to be built quickly and efficiently.
