* Change disconnect function
Current implementation does not disconnect the WiFi. Use of `esp_wifi_disconnect()` does.
* Update WiFiSTA.cpp
put back the clear ssid + password
remove the duplicate `esp_wifi_set_config(WIFI_IF_STA, &conf);`
send() can return a value > 0 but less than size indicating it was able to accept some of the data in buffer. The caller must try again after updating the buffer pointer and size remaining.
* Update WiFiAP.cpp
set from code the maximum number of clients to smaller than 4 (in my case i must allow only one client at a time)
* Update WiFiAP.h
* Update WiFiAP.cpp
* Update WiFiAP.cpp
* Create WiFiAP.cpp
Actually WiFiMulti is not working due some functions haven't equal comportment of ESP8266
Replace status == WL_DISCONNECTED => status != WL_CONNECTED
Replace scanComplete() => scanNetworks()
Maybe is more interesting, for keep the maximum compatibility, investigate why WL_DISCONNECTED and scanComplete() doesn't works in this case instead of just replace by this pull request.
* Rework WiFiClient
Rework WiFiClient to correct error where making a copy of a WiFiClient object resulted in the socket being closed prematurely.
Added loop and select to write to handle/prevent EAGAIN errors.
* Rework WiFiClient to use shared_ptr
Rework changes to utilize shared_ptr rather than manually maintaining reference count.
Revert changes to write
* Incorporate comments from review
Move WiFiClientSocketHandle and fd() into WiFiClient.cpp
The send call may return EAGAIN. This indicates a recoverable error and a retry should be attempted. The current implementation treats this as a fatal error. Further, the current implementation strips the error code, setting it to 0, which prevents the caller from handling it directly.
This change utilizes select to verify the socket is available prior to calling send and will retry on an EAGAIN condition.
WiFi and BlueTooth can now be started and stopped at will.
basic functions added to esp32-hal to start and stop the BT radio
SimpleBLE class added to show the most basic functionality
Example to show how to switch between BT, WiFi or Both
Currently there is bug in WiFiUDP library when you want to use beginPacket(...) without listening on socket (without calling begin(...) first). You can't send any data because socket is not open and also tx_buffer is not allocated which cause crash while writing data to tx_buffer.
