This board does not have an onboard debugger, and can only upload programs via UART |

Thank you for your response, we are able to buy ftdi device, but another
error occur, it says "Invalid Head of packet: Possible noise or serial
corruption" can you help us with this pls.

You don't need to buy an FTDI device, just plug the USB-C to the TTL port, select the serial port in the Arduino IDE and click upload. |

Thanks, it does work. I appreciate how responsive you all are. This time,
we are encountering this error
Initializing GSM module...
Failed to restart modem. Check power or connection.
Initializing GSM module...
Failed to restart modem. Check power or connection.
What could be the possible issue this time?
Thank you so much.

If you encounter a problem where you can't upload, take a wire, connect
GPIO0 to GND, then power on, and click upload. After the upload is
complete, remove the wire, exit download mode, and press reset. It should
work now.

When I asked you this, I guessed that you didn't do anything to turn on the modem. Please check the examples we provided. The modem must be turned on before it can be used. T-SIM7600X/examples/ATdebug/ATdebug.ino Line 46 in 350b1c5 |

we'll check it out, thank you so much sir !!

Our group had a lot of progress on our project, thank you for responding so
quickly. This time we are encountering an error where the location is not
sent to the registered number, is there another thing that needs to be
activated just like the modem?

What does it mean? I don't understand? The modem must be manually activated every time it is turned on |
|
our project supposed to sent sms containing device's location to a
registered number, but unfortunately, it is not working, the board don't
send sms to a registered number, is there something that can be done? thank
u always

(sizeof(fonaNotificationBuffer) - 1)));
// Add a terminal NULL to the notification string
*bufPtr = 0;
// Scan the notification string for an SMS received notification.
// If it's an SMS message, we'll get the slot number in 'slot'

You should use a minimal example to test whether you can send the location via SMS without adding any business logic. Here is a simple demonstration. |

we'll try it out thankss

we're too shy to ask but sorry, we are desperately really in need of your
help, we are already receiving sms containing the location, but we need it
to be activated first by sending sms to the esp32 before it will send the
sms with the location. I hope you can help us please.
