ESP32

failed to load RF calibration data †[edit]

错误现象：

W (54) phy_init: failed to load RF calibration data (0x1107), falling back to full calibration
Brownout detector was triggere

原因：电流不足。

对策：

禁用掉这个选项，将不再检测电平。

make menuconfig->component config->ESP32-specific->Hardware brownout detect & reset

或者也可在再这个选项的下面选择一个更合适的保护电平。

重启原因 †[edit]

• TG0WDT_SYS_RESET = 7, /**<7, Timer Group0 Watch dog reset digital core*/
• TG1WDT_SYS_RESET = 8, /**<8, Timer Group1 Watch dog reset digital core*/ 也有可能因为电压、电流不稳造成的。

tcp_poll_read select error 113 †[edit]

wifi 掉线了，需要重新连接wifi

TRANS_TCP: tcp_poll_read select error 113, errno = Software caused connection abort, fd = 54
MQTT_CLIENT: Poll read error: 119, aborting connection
TRANS_TCP: DNS lookup failed err=202 res=0x0
MQTT_CLIENT: Error transport connect
MQTT: MQTT_EVENT_ERROR.

wifi:pm stop, total sleep time †[edit]

Wifi的节电模式打开了（ESP32 idf的默认模式有可能时节电模式）

I (532989) wifi:state: run -> init (6c0)
I (532999) wifi:pm stop, total sleep time: 491610374 us / 531899959 us
I (532999) wifi:new:<3,0>, old:<3,0>, ap:<255,255>, sta:<3,0>, prof:1
W (532999) wifi:Haven't to connect to a suitable AP now!
W (533009) wifi:Haven't to connect to a suitable AP now!

在esp_wifi_start()函数之后，添加下面的代码

esp_wifi_set_ps(WIFI_PS_NONE);

wifi:sta is connecting, return error †[edit]

Brownout detector was triggered †[edit]

USB供电不稳，使用外接充电头供电即可

rst:0x10 (RTCWDT_RTC_RESET),boot:0x33 (SPI_FAST_FLASH_BOOT) †[edit]

问题的出现和上电时GPIO状态有关，大概率是上电以后某个GPIO的电压。

程序里面不要使用 GPIO 12、15
