@jeets +CSQ: 99,99 tells me that you don't have a signal.

@felmue Indeed, According to the manual Ready means MT is not pending for any password.

For those that need to connect their devices to a Eduroam network, this is a great link which helped me to get it working :

Many thanks to Martinus96!

Thanks,
Indeed,
This works :
display.drawJpg(JPG_buffer_processed, Append_this_Struct.JPG_size, 0, 0, Append_this_Struct.JPG_width,Append_this_Struct.JPG_height,0,0,JPEG_DIV_2);

I know this is not completely the right topic.
Anyway,
I want to scale my jpg, lets say to half its size. I am trying to understand the syntax, but no luck.
This is what I use :
display.drawJpg(JPG_buffer_processed, Append_this_Struct.JPG_size, 0, 0, Append_this_Struct.JPG_width,Append_this_Struct.JPG_height, 1.0f, 0.5f)
assuming the last two floats are a scale factor.
But my jpg stays the same size.
Anyone any idea how to scale my jpg ?
thanks

#include <HardwareSerial.h>
HardwareSerial Comm(1);

Comm.begin(115200, SERIAL_8N1,TX_pin,RX_pin); // TX RX

Comm.print("AT+IPR=115200\r"); // Set text mode

Last command should return an OK. If not, it could be that you have mixed up TX and RX pins or a power issue.

To read the reply from the module you could use something like this :
while (millis()<wait_until)
{
while (Comm.available())
{
ccc=Comm.read();
//Serial.print(ccc);
if (k<buffer_size-1)
{
Receive_buffer[k]=ccc;
k++;
}
}
Receive_buffer[k]=NULL;
if (strstr(Receive_buffer,StopCharArray)!=NULL)
{
//Serial.println("OK found");
// SIM7600_Error=0;
Receive_buffer[k]=NULL;
return false;
}
}

You may also try to remove the simlock of your card.

@felmue But that is great. That means that I can turn off the SIM7080 module during sleep mode. Ha Ha. (this topic was also addressed in another threat).
Btw I now also read the M5EPD.h and schematic and understand your explanation. Thanks.

I am trying to understand what power is exactly being shutdown?
Thanks
