However, the ESP32 series of chips and modules cannot undergothe BT Adaptivity test at this stage. Thus, we have lowered the maximum TX power of the ESP32 series ofchips and modules from 12 dBm to 9 dBm. Therefore, the datasheets of these chips and modules havebeen updated to reflect this change.变更描述/Description of Change:变更影响/Impact of Change:ESP32 系列产品规格书修改：技术规格书中的 BT/BLE 传输功率范围由 -12 dBm~ +12 dBm 改为 -12dBm~ +9 dBm。Revised datasheets of the ESP32 series of chips and modules: the BT/BLE TX Power Range described inthese datasheets has been updated from -12 dBm ~ +12 dBm to -12 dBm ~ +9 dBm.影响产品/Impacted Products: ESP32-WROOM-32 ESP32-WROOM-32D ESP32-WROOM-32U ESP32-SOLO-1 www.espressif.com Page2/3 ESP32-WROOM-32DC ESP32-WROOM-32UC ESP32-SOLO-1C ESP32-WROVER ESP32-WROVER-B ESP32-WROVER-BC ESP32-PICO-D4 ESP32-D0WD ESP32-S0WD ESP32-D0WDQ6 ESP32-D2WD变更识别方式/ Change Identification Method: 变更前：技术规格书中的 BT/BLE 传输功率范围为-12 dBm ~ +12 dBmBefore change: BT/BLE TX Power Range in the respective datasheets was -12 dBm~ +12 dBm 变更后：技术规格书中的 BT/BLE 传输功率范围为 -12 dBm ~ +9 dBmAfter change: BT/BLE TX Power Range in the respective datasheets is -12 dBm ~ +9 dBm now.变更前后产品处理/:How to Deal with Products:不影响/No need for action by the customer相关报告/Report(s) Attached:Related ECN No.:ECN-02-20190115Reliability Report or Plan:Function Test Report:RoHS/HF Test Report:Other Reports (Pls specify):邮件订阅Espressif Email Notifications乐鑫为注册用户提供电子邮件通知服务，用户可通过乐鑫订阅系统接收技术文档更新、新闻通讯、PCN 等邮件通知。Espressif sends email notifications of technical documentation changes, along with newsletters, PCNs andother valuable information, to subscribed customers only.
