* - In order to lower the power comsumption, ESP8266 changes the TCP timer

* tick from 250ms to 3s in WIFI_LIGHT_SLEEP mode, which leads to increased timeout for
|
|
* TCP timer. Therefore, the WIFI_MODEM_SLEEP or deep-sleep mode should be used

* Sleep is disabled in core 2.4.1 and 2.4.2 as there are bugs in their SDKs

|
|
* IP detection revised for full IPv4 / IPv6 support
|
|
*
|
|
* In general, each interface (Wifi/Eth) can have 1x IPv4 and
|
|
* 2x IPv6 (Global routable address and Link-Local starting witn fe80:...)
|
|
*
|
|
* We always use an IPv4 address if one is assigned, and revert to
|
|
* IPv6 only on networks that are v6 only.
|
|
* Ethernet calls can be safely used even if the USE_ETHERNET is not enabled
|
|
*
|
|
* New APIs:
|
|
* - general form is:
|
|
* `bool XXXGetIPYYY(IPAddress*)` returns `true` if the address exists and copies the address
|
|
* if the pointer is non-null.
|
|
* `bool XXXHasIPYYY()` same as above but only returns `true` or `false`
|
|
* `String XXXGetIPYYYStr()` returns the IP as a `String` or empty `String` if none
|
|
*
|
|
* `XXX` can be `Wifi` or `Eth`
|
|
* `YYY` can be `` for any address, `v6` for IPv6 global address or `v6LinkLocal` for Link-local
|
|
*
|
|
* - Legacy `Wifi.localIP()` and `ETH.localIP()` always return IPv4 and nothing on IPv6 only networks
|
|
*
|
|
* - v4/v6:
|
|
* `WifiGetIP`, `WifiGetIPStr`, `WifiHasIP`: get preferred v4/v6 address for Wifi
|
|
* `EthernetGetIP`, `EthernetGetIPStr`, `EthernetHasIP`: get preferred v4/v6 for Ethernet
|
|
*
|
|
* - Main IP to be used dual stack v4/v6
|
|
* `hasIP`, `IPGetListeningAddress`, `IPGetListeningAddressStr`: any IP to listen to for Web Server
|
|
* IPv4 is always preferred, and Eth is preferred over Wifi.
|
|
* `IPForUrl`: converts v4/v6 to use in URL, enclosing v6 in []
|
|
*
|
|
* - v6 only:
|
|
* `WifiGetIPv6`, `WifiGetIPv6Str`, `WifiHasIPv6`
|
|
* `WifiGetIPv6LinkLocal`, `WifiGetIPv6LinkLocalStr`
|
|
* `EthernetGetIPv6, `EthernetHasIPv6`, `EthernetGetIPv6Str`
|
|
* `EthernetGetIPv6LinkLocal`, `EthernetGetIPv6LinkLocalStr`
|
|
*
|
|
* - v4 only:
|
|
* `WifiGetIPv4`, `WifiGetIPv4Str`, `WifiHasIPv4`
|
|
* `EthernetGetIPv4`, `EthernetGetIPv4Str`, `EthernetHasIPv4`
|
|
*
|
|
* - DNS reporting actual values used (not the Settings):
|
|
* `DNSGetIP(n)`, `DNSGetIPStr(n)` with n=`0`/`1` (same dns for Wifi and Eth)
