* Suppressed -Wunused-parameter and -Wunused-function by casting to void unused identifiers.
* Explicit initialization of all fields to suppress -Wmissing-field-initializers.
* Fixed signed/unsigned integer comparison.
* memset initialization of structs.
* More -Wunused-parameter fixes.
* Fixed libb64 decoder.
Libb64 decoder works when "char" type is signed. In esp8266 xtensa gcc "char" is unsigned, so libb64 decoder does not work. In the implementation file I replaced "char" to "int8_t" and created function wrappers in order to keep existing interface.
* For style consistency.
* Prevent divide by zero error causing code to crash
As per the issue at #2491, there is a divide by error issue resulting from the specification of 0 as the frequency. This does not appear to affect the AVR implementation, but it crashes on ESP8266s. I have merely removed the division if the frequency is zero, which appears to be giving the expected results (no tone), without any code crashes.
To test, simply load the toneMelody sketch included with the Arduino IDE (Examples -> 02. Digital -> toneMelody) and change the piezo to something else if you need to. On the Witty module used to test this, I could also tell by the wifi led blinking every time the code crashed as the ESP8266 immediately rebooted.
* Use noTone when frequency is zero
When a frequency of zero is given to tone(), instead call noTone() and exit. Placed after some of the initialisation stuff to ensure the pin is mapped as a output, etc. Tested as functional against a Node MCU 1.0 board and the toneMelody example sketch, using GPIO5 (pin D1).

* Rest of tabs that crept in from web editor
Defaulted to tabs and 8 indent :sigh:
Bind the UDP connection to IP_ADDR_ANY rather than a specific interface
IP, so that it can receive queries from all interfaces at once.
When processing a query, detect which interface it was received on, and
pass this information to the reply code. Set the IP multicast interface
before each transmission, so that we can route each packet to a
different interface if required. These changes enable the code to
respond correctly on both AP and STA interfaces at once. The original
code only worked correctly for the STA interface if both were enabled.
When advertizing all services, do it on both AP and STA interfaces if
they're both enabled.
Provide an API for the application to notify the MDNS code if the AP
configuration changes (enabled, disabled, IP changed). Ideally, the WiFi
core would provide an event callback for this purpose, as it does for
STA changes, but it does not appear to, so the application must provide
this information.
Manually specifying the AP IP isn't required; the next change will modify
the MDNS code to correctly handle any combination of AP and STA modes, and
correctly respond to requests on all active interfaces.
This reverts commit b682d597c5.
For downcasting, static_cast<> is the appropriate cast. Using reinterpret_cast<> will NOT correctly adjust the `this` pointer and dereferencing such a value is undefined by spec. See [expr.reinterpret.cast]p7 for the relevant passage. The only legal use of this pointer is in another set of reinterpret_cast expressions that either land it into a numeric value, or back to the original type.
Many people have problems with using ESP8266 as WiFi-client due to
none of the examples mentioning that you should use WIFI_STA if you
only want the ESP8266 to act as a WiFi-client. Many WiFi-devices
will randomly try to connect to the ESP8266 if used as STA+AP and
complain about not being able to access the Internet or other devices
on the network.
About the simplest change possible, just delete two characters and add one. The PUT(String) convenience method called the full POST method instead of calling the PUT method
gettimeofday used to return timestamps which had tv_sec 1000 times smaller than the correct value.
s_bootTime is in seconds, so no need to divide it by 1000.
this fix forces the mDNS to use the provided IP in the begin method
instead of the auto detected IP. this is required if the ESP8266 starts
in the AP_STA mode and activates only the AP initially.
* Optimize MDNS to prevent overflow and endless loop
* Handle better non-esp services
* leave debug off
* better name resolution for external devices
* strip name length (did not show in IDE)
* Update ESP8266WiFiAP.cpp
It is not very common but some might require to set the maximum number of clients, from code, to smaller than 4.
in my case i must allow only one client at a time (TESTED WORKING)
* Update ESP8266WiFiAP.h
as discussed in the .cpp (set max connections)
* Update ESP8266WiFiAP.cpp
corrected indentation @70
add param comment @86
* Update ESP8266WiFiAP.cpp
