FAQ's for ACK Module with Espressif chipset

What is ACK Module with Espressif chipset?
ACK Module with Espressif chipset is another Alexa Connect Kit (ACK) Module that device makers can use to prototype smart IoT products to add Alexa command and control capabilities in it. The ACK Module with Espressif chipset is currently available for developer preview only.

What features are available/unavailable in ACK Module with Espressif chipset developer preview?
For developer preview, device makers are able to prototype a product by using new ACK Module with Espressif chipset i.e. perform product provisioning, registration, command and control, generate logs, metrics and access all available ACK module firmware CLI commands at module provisioned, product provisioned and product locked stages. Developers are able to use existing latest ACK device SDK to create HMCU applications with ACK Module with Espressif chipset. Developers are also able to perform OTW updates of firmware on ACK Module with Espressif chipset using Module Utility 5.0.10.0 designed for this specific module.
Performing OTA updates for ACK firmware, HMCU firmware and zero touch setup (ZTS) are unavailable with developer preview of ACK Module with Espressif chipset.

Note: After module is locked using lockmodule CLI, Over-the-air (OTA) or Over-the-wire (OTW) updates to ACK Module firmware (ACK Module with Espressif chipset) are disabled. Avoid using this command with ACK Module with Espressif chipset firmware 1643 version unless for mass production testing.
