Clean disconnection of wifi by calling esp_wifi_stop()

Why I get message :

Code: Select all

E (21326) event: system_event_sta_disconnected_handle_default 294 esp_wifi_inter
nal_reg_rxcb ret=0x3014
When I call

Code: Select all

esp_wifi_stop();
.
How can I stop WiFi in clean way so that mqtt don't get "lwt" message?

Fuel Gauge to go with ESP32

Has any body any experience of using fuel gauge,like MAX17044, MAX17048 or any other, with ESP-IDF?
Or using ADC reading is the only choice to get LiPo battery condition?

Re: Measure LiPol battery level

Hi
@wyattisawesome which fuel gauge chip/module can be used with ESP-IDF? Have you successfully used any fuel gauge with ESP32?
