Hi,

AT Commands are not supported in our Bluetooth devices. You will have to use HCI commands & events if you need to interact with the controller  (if you are using the device in controller mode and an external host). 

 

If you have use cases that cannot be handled easily with the EZ-Serial provided firmware, use the Modustoolbox (with BTSDK) to build your application firmware image. EZ-serial firmware source code is not made public. But you can use our SDK to build any feature/functions you require on your chip. 

Please note CYW20719B2 is supported in Modustoolbox. CYW20719B1 is only supported in WICED Studio SDK which is old development environment.

Thanks,
