Description
Hi,
thanks first for the awesome lib. Just trying to get started with the snapclient. With WiFi on the ESP32 it works, but I cannot get the audio 100% glitch and crack free. Thats why I now want to move to Ethernet.
I have a W5500 board, connected via SPI. That works fine, I can ping my board.
First thing I noticed when moving to Ethernet instead of wifi, is that mDNS does not work (prints an error on the serial at startup). So I disabled it (via #define CONFIG_SNAPCLIENT_USE_MDNS false) after reading that it only supports WiFi in the current implementation?
After calling client.begin() the SnapClient cannot connect to my snapcast server. All I get on the Serial output is
[ 628][E][SnapProcessor.h:296] connectClient(): [SnapProcessor] Socket connect to 192.168.10.18:1704 failed (errno = 0)
Do you have any hints? I looked at the other Ethernet related issues here, but cannot find any significant difference in the code.
This is my code:
#include <Arduino.h>
#include <SPI.h>
#include <Ethernet.h>
#include "config.h" // Must be above "SnapClient.h" include, as here are some defines, which are otherwise defaulted in "SnapClient.h/SnapConfig.h"
#include "AudioTools.h"
#include "SnapClient.h"
#include "AudioTools/AudioCodecs/CodecOpus.h"
EthernetClient eth;
byte mac[] = {0xC0, 0x49, 0xEF, 0xCE, 0x14, 0xD4};
AudioInfo infoOut(48000, 2, 16);
OpusAudioDecoder codec;
I2SStream out;
SnapTimeSyncDynamic synch(172, 10);
SnapClient client(eth, out, codec);
IPAddress ip(192, 168, 10, 99);
IPAddress gateway(192, 168, 10, 1);
IPAddress dns(192, 168, 10, 1);
void setup()
{
Serial.begin(115200);
Serial.println("Start SPI ...");
SPI.begin(18, 19, 23, 5);
// start the Ethernet connection:
Serial.println("Start Ethernet ...");
Ethernet.init(5);
// Ethernet.begin(mac);
Ethernet.begin(mac, ip, dns, gateway);
// Check for Ethernet hardware present
if (Ethernet.hardwareStatus() == EthernetNoHardware)
{
Serial.println("Ethernet shield was not found. Sorry, can't run without hardware. :(");
while (true);
}
Serial.print("Hardware type found: ");
Serial.println(Ethernet.hardwareStatus());
// Check link status
if (Ethernet.linkStatus() == LinkOFF)
{
Serial.println("Ethernet cable is not connected.");
}
// wait for link
Serial.println("waiting for link...");
while(Ethernet.linkStatus() != LinkON)
{
delay(1000);
}
Serial.println("Ethernet link Up");
Serial.print("local IP: ");
Serial.println(Ethernet.localIP());
Serial.println("starting I2S...");
// setup I2S to define custom pins
auto cfg = out.defaultConfig();
cfg.copyFrom(infoOut);
cfg.pin_data = 19;
cfg.pin_bck = 18;
cfg.pin_ws = 5;
// cfg.pin_mck = 0;
cfg.i2s_format = I2S_STD_FORMAT;
cfg.buffer_size = 1024;
cfg.buffer_count = 10;
out.begin(cfg);
Serial.println("starting SnapClient...");
client.setWiFi(false);
client.setServerIP(IPAddress(192, 168, 10, 18));
client.begin(synch);
Serial.println("started...");
}
void loop()
{
client.doLoop();
}
I'm using PlatformIO, so for completeness this is my platformio.ini with the libs and versions:
