🔵 Bluetooth Questions

Q: Does it support Bluetooth Classic?
A: No, only Bluetooth Low Energy (BLE) is supported on ESP32-S3.

Q: What does "BLE Spam" do?
A: It broadcasts fake device advertisements (Samsung, Apple, Google, etc.) that appear on nearby smartphones. This demonstrates bluetooth advertising vulnerabilities. Use only in controlled environments.

Q: Can it clone my car key fob?
A: No. Car key fobs typically use:

Sub-GHz (315/433/868 MHz) rolling codes
Proprietary encryption


The optional CC1101 module can capture some signals, but cloning modern rolling-code systems is extremely difficult and often impossible.

---

💳 NFC/RFID Questions

Q: Which cards can I read?
A: The PN532 supports:

✅ MIFARE Classic (1K/4K)
✅ MIFARE Ultralight
✅ NTAG (NFC Tags)
✅ Some FeliCa cards
❌ iClass, HID Prox, EM4100 (different frequency)


Q: Can I clone my building access card?
A: Maybe. If it's MIFARE Classic, yes (if keys are default). Modern systems use encrypted cards that are very difficult to clone. Always obtain permission from the building owner before attempting this.

Q: Can I emulate cards?
A: Yes, the PN532 supports card emulation mode for some card types. See PN532 documentation for details.

Q: Why does NFC only work at very close range?
A: NFC operates at 13.56 MHz and requires very close proximity (< 5 cm). This is normal and by design.

---

🛰️ LoRa Questions

Q: What is LoRa?
A: LoRa (Long Range) is a low-power, long-distance radio protocol. It can transmit small messages up to several kilometers.

Q: Which frequency should I use?
A:

433 MHz - Worldwide (most common)
868 MHz - Europe
915 MHz - USA, Australia


Use only legal frequencies in your region. Check local regulations.

Q: Can I communicate with other LoRa devices?
A: Yes, if they're on the same frequency, spreading factor, bandwidth, and coding rate. Two SGP Card Mini devices can communicate out of the box.

Q: What is LoRaWAN?
A: LoRaWAN is a network protocol built on top of LoRa. The current firmware uses raw LoRa, not LoRaWAN (planned for future versions).

---

🛠️ Troubleshooting

Q: Device powers on then immediately turns off
A:

Battery is depleted - charge it
Battery connector is loose - check connection
Power button is stuck - clean button


Q: RGB LED doesn't light up
A:

Check LED is properly connected
Verify data pin connection (GPIO pin)
Test with different example code (Adafruit NeoPixel examples)


Q: Serial Monitor shows garbled text
A:

Set baud rate to 115200
Select correct port
Close other programs using the serial port


Q: Module not detected (LoRa/NFC/Mic)
A: This is normal if modules are not connected. The device will say "⚠️ MODULE NOT DETECTED (continuing without it)" and still work with built-in WiFi/BLE.

To fix:

Check wiring (see Hardware Connections)
Verify module power (3.3V)
Check SPI/I2C connections


Q: Web interface is slow
A:

Normal for ESP32 - it's not a high-performance web server
Reduce number of simultaneous connections
Disable browser auto-refresh features


---

🔒 Security & Privacy

Q: Does the device send data to the internet?
A: No. The firmware does not connect to external servers or transmit data online. Everything runs locally on the device.

Q: Can it be tracked?
A: The device broadcasts:

WiFi AP (SSID: SGP_CARDMINI)

BLE name (advertises as SGP_CARDMINI)



If you need stealth mode, modify the code to change/disable these identifiers.

Q: Is my data safe?
A: Any data captured (WiFi scans, BLE devices, NFC dumps) is stored locally on the device. You are responsible for securing this data.

---
