}
This function returns:
•
‘1’ on success
•
‘0’ or ‘-2’ if error
12.14. Changing the baudrate
This function changes the baudrate between Waspmote and 3G/GPRS module. This function also changes the UART’s baudrate
in Waspmote. The allowed baudrates are: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200. Higher values don’t
work properly in Waspmote.
Example of use:
{
// Sets baudrate to 38400 bauds:
_3G.changeBaudrate(38400);
}
This function returns:
•
‘1’ on success
•
‘0’ or ‘-2’ if error
12.15. Sending AT commands to the 3G/GPRS module

buffer_3G
with this format.
Example of use:
{
// Sends “AT+CREG”:

// Shows the answer:
USB.println(_3G.buffer_3G);
}
This function returns:
