The following baud rates can be configured by AT command (see
u-blox AT Commands Manual
[3], +IPR):
9600 b/s
19200 b/s
38400 b/s
57600 b/s
115200 b/s, default value for “50” modules product version or when one-shot autobauding is disabled
230400 b/s
460800 b/s
921600 b/s
The following frame formats can be configured by AT command (see
u-blox AT Commands Manual
[3], +ICF):
8N2 (8 data bits, no parity, 2 stop bits)
8N1 (8 data bits, no parity, 1 stop bit), default frame format
8E1 (8 data bits, even parity, 1 stop bit)
8O1 (8 data bits, odd parity, 1 stop bit)
7N2 (7 data bits, no parity, 2 stop bits)
7N1 (7 data bits, no parity, 1 stop bit)
7E1 (7 data bits, even parity, 1 stop bit)
7O1 (7 data bits, odd parity, 1 stop bit)
Automatic frame format recognition is not supported by “00”, “01” and “50” module product versions.
Figure 20 describes the 8N1 frame format, which is the default frame format configuration.
