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)

Attention:
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 user1.4096.new.4.bin at 0x1000 ,
user2.4096.new.4.bin 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 http://karadio.karawin.fr .

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 192.164.4.1 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. Don't 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 at the first start is 192.168.1.254
  • a sample of stations list is on https://github.com/karawin/Ka-Radio/blob/master/ESP8266-Firmware/WebStations.txt . Can be uploaded via the web page.

The O-led with arduino mini  addon work now , but the  date display  only  "01-01-2000' and the clock work like a function time counter , it count the time from powering on  .What can i do to fix this ?  Thank you !

This is because the request time from the mini is not received by the esp. Check the mini tx ---- rx esp wire

  Are you sure? yes | no

josefburgersanktmartin wrote 01/31/2021 at 08:43 • point

in my schematic the wire mini tx ---- rx esp not exist ,   only tx from ESP 8266 to rx mini , i have only 3 wires from radio to mini , 3,3V GND and  tx esp to rx mini

  Are you sure? yes | no

Jean-Pierre Cocatrix wrote 01/31/2021 at 08:50 • point

Yes a mistake.
but in u8glibConf.h you can read:

The tx of the pro mini must be connected to the rx of the esp12 but
Warning; the esp rx pin is not 5V tolerant, so if your pro mini is a 5v version we nned to adapt the level.
-------
See
http://www.instructables.com/id/Pi-Cubed-How-to-connect-a-33V-Raspberry-Pi-to-a-5V/

The value of the resistors is not critical. Only th ration 1/3 2/3 must be respected 1k and 2k for example)

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!

Hello,

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: https://github.com/martinberlin/Remora
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

Hi,

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 192.168.4.1 in my browser, it says "This site can't be reached." There is also no result pinging that IP address, but 192.168.4.2 does respond to the ping. I can't get any farther than this.

Can anyone help?

Hello,

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?

Hi, I appreciate your effort to create KaRadio. My setup works somehow but I need some help with two issues: poor sound quality and noise. 

1. Poor sound quality: I receive only a low quality mono-like sound (with some echo) with no bass unless a GND point (power extension safety GND point) is connected to the V1053 GND. With the external GND connected the sound is excellent but I would prefer to avoid another wire connected so close to 220V.
 
2. Low freqency noise -
When powered from a 5V power bank, there is no noise (still needs GND to mains GND to have good quality sound) and works perfectly.
When powered from a 5V phone charger and there is no external GND connection there is a loud low freqency noise. With the external GND connected all noise disappears and works perfectly.
Analog GND is connected to digital GND? Noise from the charger? Any ways to eliminate the noise?

My setup:
- MB102 power supply - powered from 5V power bank or phone charger through USB
- NodeMCU ESP8266 ESP-12E V1.0 - (Ka-Radio-master1.9.zip flashed with flash_download_tools_v3.6.5.exe), powered from MB102 5V, common GND
- VS1053 (red, chip ver. 1815) MP3 with SD Card Slot  - 5V from NodeMCU, GND from NodeMCU, jack connected to HiFi amplifier (which is also connected to UPC TV box)
- STM32F103C8T6 Blue Pill (karadio-addons-master\karadioUCSTM32 ver.07.02.2019 (flashed with HW-597 (CH340)) powered from MB102 5V, common GND
- 1.8" TFT ST7735B - powered from MB102 5V and 3.3V(for LCD), common GND
- KY-040 Rotary Encoder - powered from MB102 3.3V, common GND
 
So now I got stuck with an operational radio but the external GND line does not look safe. Any suggestions to improve?
