T-sim7600E don't recognize SD card
-
I successfully read SD card on my sim7600g, I mean I have "SDCard Size: 3789MB" when I run examples/Arduino_TinyGSM/AllFunctions/AllFunctions.ino. The SD card is formatted as FAT32 on Windows 10, no partition. I suggest to run one of examples such as AllFunctions.ino first.

@caz Hello,
Thanks for your reply.
Unfortunately I have tested my board with all the different exemples from the Arduino library and the result are always the same "SD card mount fail".
I have formated the various SD card on Windows 10 and MAC OS as FAt32 with the same result.

@papbo How do you attache the SD? Does its contact side face to the board? Its connector is not fail safe.
-
@caz Yes The SD is on the right side..
-
@caz hello, do you have a sketch to test the SD card on the SIM7600...other than the examples (they are not working here)

@papbo AllFunctions.ino has following code.
//Initialize SDCard
SPI.begin(SD_SCLK, SD_MISO, SD_MOSI, SD_CS);
if (!SD.begin(SD_CS)) {
Serial.println("SDCard MOUNT FAIL");
} else {
uint32_t cardSize = SD.cardSize() / (1024 * 1024);
String str = "SDCard Size: " + String(cardSize) + "MB";
Serial.println(str);
} -
@caz It is exactly what I have in my sketch (look at my first post)
Thanks

@papbo Does you code have serial port initilization code?
// Set console baud rate
SerialMon.begin(115200);
delay(10);// Set GSM module baud rate
SerialAT.begin(UART_BAUD, SERIAL_8N1, MODEM_RX, MODEM_TX); -
@caz Of course all is ok regarding UART communication...I canuse the GPS mode, the GPRS mode, wifi...AT commands , send and receive SMS..but unable to read and write to the SD card

@papbo What is your current ESP32 version? Try upgrading?
