Overview of Data Packets
Note: On December 31, 2021, we paused support for third-party device makers working with Alexa Gadgets, while we work to create an even better developer and customer experience. Please stay tuned to the Amazon developer portal for updates. In the interim, please visit the landing pages for Alexa Voice Service, Alexa Connect Kit, and Alexa Skills Kit to discover ways you can provide new customer experiences with voice.
Although the packet format does not, in a general sense, specifically relate to the Bluetooth type, in the case of gadgets they correspond as described in this documentation.
