1 Overview
从 ESP SDK v1.4.0 版本起，开发者可以通过设置 esp_init_data_default.bin (0~127 byte) 的 114 byte 控制上电时 RF 初始化的行为，具体如下：
- 114 byte 默认值为 0 ：RF 初始化仅做 VDD33 校准，耗时约 2 ms，初始电流最小；
- 114 byte 若修改为 1 ：RF 初始化做 VDD33 和 TX power CAL，耗时约 18 ms，初始电流较小；
- 114 byte 若修改为 2 ：RF 初始化仅做 VDD33 校准，耗时约 2 ms，初始电流最小；与 0 值时一致；
- 114 byte 若修改为 3 ：RF 初始化进行全部 RF CAL，耗时约 200 ms，初始电流较大
