LORA and SD card conflict

[kadrimanaj]

I'm using SPIExample.ino but when I get in the same time and SD card and LORA one of them doesn't work.

MODEL : A7670E

if I put an SD card

23:17:02.807 -> SD Card Type: SDHC 23:17:02.807 -> SD Card Size: 3840MB 23:17:02.807 -> Starting LoRa failed!

if I remove the SD card

23:17:17.306 -> Card Mount Failed 23:17:17.306 -> Sending packet: 0 23:17:18.330 -> Sending packet: 1 23:17:19.336 -> Sending packet: 2 23:17:20.332 -> Sending packet: 3 23:17:21.355 -> Sending packet: 4 23:17:22.341 -> Sending packet: 5

I see that pin 5 is in Lora and the SD card is this pin conflict? ore the library has a problem or example code?

You need to confirm whether the defined LoRa SPI pin conflicts with the SD card. You need to change the Pin. As mentioned in the example, you need to confirm whether the pin is correct before use.

SPIClass RadioSPI(VSPI);

// Setup function for initializing hardware and communication interfaces void setup() {

SerialMon.begin(UART_BAUD); // Start serial monitor communication while (!SerialMon);

 /* SD CARD Setup */
if (SD_Card()) {
    Serial.println("Using SD Card.");
    sd_card = true;
} else {
    Serial.println("Without SD card");
    sd_card = false;
}

/* Lora Setup */
SerialMon.println("LoRa Receiver");

RadioSPI.begin(LORA_SCK, LORA_MISO, LORA_MOSI);
LoRa.setSPI(RadioSPI);  

LoRa.setPins(LORA_SS, LORA_RST, LORA_DI0);
if (!LoRa.begin(FREQUENCY)) {
  SerialMon.println("Starting LoRa failed!");
  while (1);
}

LoRa.setSignalBandwidth(BANDWIDTH);
LoRa.setSpreadingFactor(SPREADING_FACTOR);
LoRa.setCodingRate4(CODING_RATE);
LoRa.setTxPower(OUTPUT_POWER);
LoRa.setPreambleLength(PREAMBLE_LENGTH);
LoRa.setGain(GAIN);
SerialMon.println("Lora ready.");

} `` Fixed
