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 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 recognition is not supported by all the TOBY-L2 modules product versions.
Figure 20 describes the 8N1 frame format, which is the default frame format configuration.
