    For ESP32 see the github page KaRadio32. Release 1.6 R4

    ESP8266 Simplest prototype:

    - Optional external ram (23LCV1024) support (1:CS/=GPIO16 2:MISO=GPIO12 3:NC 4:GND 5:MOSI=GPIO13 6:SCK=GPIO14 7:GND 8:3.3v)

    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.

    To upgrade to this release, please flash at 0x1000 , at 0X81000 and blank.bin at 0x7e000 & 0x3fe000
    After that, all next updates are done with the On The Air (OTA) feature.
    New binaries are hosted at .

    Loading the esp8266

    First use

    • If the access point of your router is not known, the webradio initializes itself as an AP. Connect your wifi to the ssid "WifiWebRadio",
    • Browse to 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....

    hank you! Production completed. It's just that China's radio streaming media does not support the display of radio program information, and the display screen looks ugly and harmonious. I want to adjust the screen display layout and enlarge the font, but I'm not very familiar with programming, and I'm only good at hardware. Hope under the guidance, thank you!

    I don't think that the esp wifi will support the stream speed for a flac.

    I have installed your Software on two ESP32 systems and booth working very well, i have only two suggestions.

    1. sometimes after power the radio, the ESP32 don´t connect to the wifi and start instead the AP, the router is not far from the ESP... and next time the ESP connect to the WIFI, maybe it is possible to programm a routine, when AP is active, check every 5 minutes to stored WIFI networks.

    2. somitimes when i switch a light in the near of the Radio, i hear a knock at the speaker and the radio is loudless, after a restart the radio is working well. Ithink the problem is the VS1053, maybe it is possible to check if the VS1053 is working, if not, give him a reset.

      Are you sure? yes | no

    Martin Fasani wrote 01/15/2020 at 15:23 point

    I have a suggestion about that: Instead of using WiFi manager, let WiFi configuration come from Bluetooth serial or BLE (Serial is a smaller lib)
    Here there is an example:
    There is an Android app called "ESP32 WiFi setup over BLE or Bluetooth Serial" and then you can easily setup the Radio via Bluetooth

      Are you sure? yes | no

    I like this project but haven't had much success. I'm using a nodemcu v.3 with an ESP8266 and a VS1053. After flashing the nodemcu, I can see a response from it in a terminal program. Following the directions in the response, I can connect to WifiKaRadio successfully, but when I enter in my browser, it says "This site can't be reached." There is also no result pinging that IP address, but does respond to the ping. I can't get any farther than this.

    Can anyone help?

      Are you sure? yes | no

    Sera26 wrote 05/13/2019 at 18:52 point


    Playing of radio stations are lagging strongly with KaRadio, the streams are unpalatable.

    I have already removed control buttons (ADC and GND bridged) and STM32+LCD but radio can't play stations continuously.

    What can be the problem?

    Can the project work as-is if I do not connect any display or key, or does it require some tuning?

    Is any Arduino-IDE version available?

    Jean-Pierre Cocatrix wrote 05/13/2019 at 11:06 point

    Yes. no tuning but better with a little effort. (no lcd (sys.lcd("255"))

    No, it is an esp_idf project only.

    Is this possible to integrate IR receiver in order to use any remote control. So you can learn commands from your Rc then map it at CSV

    Jean-Pierre Cocatrix wrote 05/13/2019 at 11:08 point

    You can learn codes with the log at sys.logd level then map them in the csv.
