esp_yield() now also calls esp_schedule(), original esp_yield() function renamed to esp_suspend(). Don't use delay(0) in the Core internals, libraries and examples. Use yield() when the code is supposed to be called from CONT, use esp_yield() when the code can be called from either CONT or SYS. Clean-up esp_yield() and esp_schedule() declarations across the code and use coredecls.h instead. Implement helper functions for libraries that were previously using esp_yield(), esp_schedule() and esp_delay() directly to wait for certain SYS context tasks to complete. Correctly use esp_delay() for timeouts, make sure scheduled functions have a chance to run (e.g. LwIP_Ethernet uses recurrent) Related issues: - #6107 - discussion about the esp_yield() and esp_delay() usage in ClientContext - #6212 - discussion about replacing delay() with a blocking loop - #6680 - pull request introducing LwIP-based Ethernet - #7146 - discussion that originated UART code changes - #7969 - proposal to remove delay(0) from the example code - #8291 - discussion related to the run_scheduled_recurrent_functions() usage in LwIP Ethernet - #8317 - yieldUntil() implementation, similar to the esp_delay() overload with a timeout and a 0 interval
ESP8266 Multicast DNS
A port of CC3000 Multicast DNS library (version 1.1)
This is a simple implementation of multicast DNS query support for an Arduino running on ESP8266 chip. Only support for resolving address queries is currently implemented.
Requirements
- ESP8266WiFi library
- MDNS support in your operating system/client machines:
- For Mac OSX support is built in through Bonjour already.
- For Linux, install Avahi.
- For Windows, install Bonjour.
Usage
- Download this repository as a zip (button on the right) and follow these instructions to install into Arduino.
- Include the ESP8266mDNS library in the sketch.
- Call MDNS.begin method in the sketch's setup and provide a domain name (without the '.local' suffix, i.e. just provide 'foo' to resolve 'foo.local'). Optionally provide the IP address to advertise and time to live (in seconds) for the DNS record -- the default is 1 hour.
- To advertise DNS-SD services, call MDNS.addService(service, proto, port), where service and proto are strings with service and protocol name (e.g. "http", "tcp"), and port is an integer port number for this service (e.g. 80).
See the included MDNS + HTTP server sketch for a full example.
