### Release 1.5- Built on 2017/08/07 New:
  • Deeply tuned and optimized
  • Added: a button erase on the station edit
  • Little change of the menu labels.

Release 1.4.2 - Built on 2017/08/01

New:
Unable to make the Espressif RTOS SDK 1.5.0-dev working, so I fed up.

  • This 1.4.2 is able to play every 320Kb/s stations.
  • New command: sys.version : Display the current Release and Revision.
  • As always, more free ram memories. The websocket and telnet tasks are now one task for both.
  • The web interface loading speed is improved.
  • A telnet server multi clients on port 23. It is the same interface as the uart one. So the low level management can be done via the network and it offer a complete interface for remote addons.
  • A deep modification of the memory management. More free room.
  • new commands: help and sys.adc.
  • The web volume command is now on a POST if the websocket is not ready.
  • Play all 320Kb/s Stations
    -new command: sys.version

Bugs resolved:
- a problem on the web interface close resolved.
A lot!
1.4.1 crashed on stations reload and some other occasions.
Improved: the second AP connection.
Improved: low bitrate stations meta decoding.
cli.list modified. Now for a complete listing, each line begins with CLI.LISTNUM to avoid interference with addons.

The optional led is now on GPIO2. The blue led on the ESP8266 is blinking at the same rate.
GPIO16 is now the Chip select for the external ram if any.
The external ram is detected at boot time if present.

Loading the esp8266

The binaries are on ESP8266-Firmware/bin/upgrade/

First use

  • If the acces point of your router is not known, the webradio inits itself as an AP. Connect the wifi of your computer to the ssid "WifiWebRadio",
  • Browse to 192.168.4.1 to display the page, got to "setting" "Wifi" and configure your ssid ap, the password if any, the wanted IP or use dhcp if you know how to retrieve the dhcp given ip (terminal or scan of the network).
  • In the gateway field, enter the ip address of your router.
  • Validate. The equipment restart to the new configuration. Connect your wifi to your AP and browse to the ip given in configuration.
  • Congratulation, you can edit your own station list. Dont forget to save your stations list in case of problem or for new equipments.
  • if the AP is already know by the esp8266, the default ip is given by dhcp.
  • a sample of stations list is on https://github.com/karawin/ESP8266-WebRadio/blob/master/ESP8266-Firmware/WebStations.txt . Can be uploaded via the web page.
  • Karadio can be controlled by the web interface or by the uart interface or by telnet. List of commands: type help
  • See the list of command at http://karadio.karawin.fr/Interface.txt
