Installation Instructions

1. Access the Application:

   • Visit apps.raspiaudio.com using Chrome.

2. Connect the Device:

   • Power on the Muse Radio and connect it to your computer via a USB data cable.

3. Setup Muse Radio:

   • Select "Muse Radio - Radio" on the website.
   • Click "Connect" and choose the appropriate COM port.

4. Set Up WiFi:

   • After the 2-minute download, configure your WiFi credentials directly in the browser (an offline option) or through the on-screen menu.

5. Troubleshooting:

   • For any issues during installation or usage, please open an issue on GitHub.

Updates

Version 1.2:

• Fixed AAC support and corrected slow pitch artifacts in MP3 playback.

Recent Changes

• Multiple Wi‑Fi credentials: Credentials are now stored in LittleFS at /wifi.json and loaded into WiFiMulti on boot. You can add multiple networks (via Settings or Improv), and the device will try them in order. Legacy /ssid and /pwd are still updated for compatibility.
• Retry/Forget/Add flow on failure: If Wi‑Fi cannot connect, a small on‑device menu lets you Retry, Forget a saved network (with double confirmation to avoid mistakes), or Add a new network.
• Long password display: The password entry screen wraps long Wi‑Fi passwords onto two lines for readability.
• USBSerial compatibility: Added a small alias so sketches build on boards without native USB CDC. When ARDUINO_USB_CDC_ON_BOOT is not defined, USBSerial maps to Serial.

Future Features

• Wi‑Fi WPS support

Development Setup

Libraries & Tools Required

• Copy the libraries directory to your local libraries folder.
• ESP32 Arduino 2.0.13.
• Install the LittleFS plugin in Arduino IDE.

Flashing and Uploading Data

• Upload your data directory using LittleFS. If upload doesn’t start automatically, you may need to:

  • Press the hidden IO0 button with a paperclip inserted in the headphone jack.

• To flash precompiled firmware, use the following command (adjust with your serial COM port and file name):

  esptool -p COM16 -b 1000000 write_flash 0 myfirmware.bin

Recompilation Parameters

• Use specified Arduino parameters as shown in your IDE settings.
