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?

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.

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?

Hello Jean-Pierre and everybody!

Could you advice me? I'm trying to do KaRadio32 with the ESP32 Devkitv1, but something's wrong. I suspect "Flash download tools" can't do with my ESP properly. 

First it couldn't download KaRadio32 to the ESP32 (esp_sync_blocking), but later I managed to erase (only pressing boot while ....._____....._____). Only after this I finally loaded KaRadio32 to my ESP32. I linked it to WiFi but monitoring worked during near minute and finished. Maybe the device is defected? But later I installed Mongoose OS to the ESP32. It worked and exchanged data via WiFi. I've not recieved an amplifier from Aliexpress yet, so can't test lineout.

Is there another loader for ESP32, not "Flash download tools"? And maybe I can do something else?

Thank you in advance!

  Are you sure? yes | no

makersting wrote 07/04/2018 at 12:54 • point

Hello Jean-Pierre,

somehow I managed to get contact to the ESP via my mobile. When I first entered the wifi-settings, I broke up to fast: I only filled in the information for my home-ssid and its passowrd, then I accidently saved before I filled in the IP-adress of the router. Now I cant find the ESP any more in the WiFi-net. What can I do?

Thanx!

Edit: I maneged to fix the problem. Actualy it was a network problem, so it has had nothing to do with Karadio.

Thanx for the effort creating this great internet-radio, Jean-Pierre!

Hello, I build this project with a esp32 and all run for the best but i would like to move the VSPI pins (18/19/23/5) to the HSPI pin (12/13/14/15) for a simplification of a PCB design and  this don't run.

The web and telnet is OK, i can use the radio but nothing is display on the LCD.

(Type 197 ) 

I test the screen with another soft and it'ok.

I checked all the GPIO.H and all the files where SPI is called but i didn't found where i made a mistake.

Could you help me ?

Mmh, using telnet/uart I was able to change to the correct display, did a system reboot and an ota update...so that all works nicely.  Log does not show any errors. Log states "playing". So I tested it with vs1053 patch (what is it for?) and without...same behavior, it suddenly stops audio after some short time.

Seems so. Whole yesterday evening I tested and had Trouble even with local Radio streams. Webpage and LCD still running until a station Change, then it completely hangs. I will reorder some Hardware.... Interestingly I used exactly this VS1053 with an ESP8266 and your Software without issues...

Hello JP,

are there any known stability issues in 1.6.3?

I tried to build a new  Karadio and after updating  to 1.6.3 i have bootloops.

Tried on different modules. After Reflashing back to 1.0.8 it works stable.

Any Idea?


Thanks

Thomas

  Are you sure? yes | no

Jean-Pierre Cocatrix wrote 03/21/2018 at 08:23 • point

From 1.0.8 to 1.6.3, it is a big jump. I think that it will be useful to erase all the flash eprom, all 4MB.

  Are you sure? yes | no

Thomas wrote 03/21/2018 at 09:25 • point

I have the binaries 1.0.8 laying around. And ever i build a new karadio i flash them and than i update via the Webinterface Update button.

But you're right. It is a big Jump. I will download new binaries from your Github, erease the whole flash and try again.

Flash Pattern is still identical?

1. Boot

2. User1

3. User2

4. blank

5. blank

6. default

7. default

Hello JeanPierre. Thank you very much for your great useful work for us. I want to modify my radio (add the WEB function to it) So I had an little idea about it, maybe she is not new, of course, but I decided to share it with you. My radio on the side can play files from USB, Micro SD, Bluetooth and AUX. Also my radio have a Ir RC. Aliexpress sells many similar low cost modules.  The idea of controlling my radio by 1 wire (through Ir line) - by small means we get more opportunities. 

How do you like this?
