Hi WiFive,

Thanks for the advice, the post you send me seem to solve my problem.
Above fix was committed on 1 Jun 2020 which is quite long time ago.
Just curious which esp-idf version are you using, why it does not has this fix?

Is there any api to know the reason of ETHERNET_EVENT_DISCONNECTED

My device sometimes got ETHERNET_EVENT_DISCONNECTED after running for several days. Checking the esp-idf code, it's because got ETH_STATE_LINK with link == ETH_LINK_DOWN. I'm sure nobody touches the device, the device just got ETHERNET_EVENT_DISCONNECTED then got ETHERNET_EVENT_CONNECTED and continu...

Re: ESP32 Adding SMA Antenna only for WiFi or Bluetooth

You can't separate BT and WiFi as apart from the antenna, they also share the radio they use to send and receive signals. We have pretty good WiFi and BLE coexistence, and there is no reason why you wouldn't be able to keep a BT connection going while you disconnect and reconnect WiFi. I heard ESP3...

System log shows: I (270506) wifi:state: run -> init (ce00) The disconnect reason code (0xce00) is: WIFI_REASON_AP_TSF_RESET. What is your esp-idf ver...

Re: ESP32 disconnect from AP

Hi axellin, We are seeing the same behavior, that Wifi randomly disconnects. Did you ever manage to solve the problem We are running ESP-IDF 4.1 [7b7c641076ef4c5dff7b994170d445bbb46f81ab] /Erik Check if upgrading v4.1 branch (git pull) helps which includes https://github.com/espressif/esp32-wifi-li...

Hey all,

Problem is that the ppp protocol example doesn't work with ESP-IDF V4.1 (5d258af)
Check if recent v4.1 update works. https://github.com/espressif/esp-idf/co ... lease/v4.1
