However, the GPIO 16 is currently used for deep sleep wakeup. Antenna diversity is removed from section 1.1, Wi-Fi Key Features and section 3.4.1, Wi-Fi Radio and Baseband of ESP8285 series of chips in this update to the datasheet. 变更内容/Proposed Change 移除 ESP8285 系列芯片的技术规格书栏目 1.1 以及栏目 3.4.1 中提及的天线分集功能。 Removing the antenna diversity feature mentioned by section 1.1 and section 3.4.1 in the datasheet of ESP8285 series of chips. 影响产品/Impacted Products: ESP8285N08 ESP8285H08 ESP8285H16 变更对比/Before and After the Change: 变更前/Before Change： www.espressif.com Page 2 / 4 1.
