SARA-G3 modules’ autobauding and SARA-U2 modules’ one-shot autobauding are enabled by default.
The following baud rates can be configured by AT command (see the u-blox AT Commands Manual [3], +IPR):
 1200 bit/s
 2400 bit/s
 4800 bit/s
 9600 bit/s
 19200 bit/s
 38400 bit/s
 57600 bit/s
 115200 bit/s, default value when the autobauding or the one-shot autobauding are disabled
 230400 bit/s
 460800 bit/s
 921600 bit/s
1200 bit/s, 230400 bit/s, 460800 bit/s and 921600 bit/s baud rates are not supported by SARA-G3
modules.
460800 bit/s and 921600 bit/s baud rates cannot be automatically detected by SARA-U2 modules.
SARA-G3 modules support the automatic frame recognition in conjunction with autobauding.
SARA-U2 modules support the one-shot automatic frame recognition in conjunction with one-shot autobauding.
SARA-G3 series modules’ automatic frame recognition and SARA-U2 series modules’ one-shot automatic
frame recognition are enabled by default, as autobauding and one-shot autobauding.
The following frame formats can be configured by AT command (see the u-blox AT Commands Manual [3],
+ICF):
 8N1 (8 data bits, no parity, 1 stop bit), default frame configuration with fixed baud rate
 8E1 (8 data bits, even parity, 1 stop bit)
 8O1 (8 data bits, odd parity, 1 stop bit)
 8N2 (8 data bits, no parity, 2 stop bits)
 7E1 (7 data bits, even parity, 1 stop bit)
 7O1 (7 data bits, odd parity, 1 stop bit)
Figure 25 describes the 8N1 frame format, which is the default configuration with fixed baud rate.
