MIA-M10Q - Integration manual
Parameter
Description
CFG-QZSS-
USE_SLAS_RAIM_UNCORR
If this configuration is set, the receiver will try to estimate the position by using only
corrected measurements; if all corrected measurements are not available, it will not
use any corrections. If this configuration is not set, the receiver will mix corrected
and uncorrected measurements for the navigation solution.
Table 12: QZSS SLAS configuration parameters
If the RAIM option is set, QZSS is the only GNSS time system that measurements can
observe.
2.3 Communication interfaces and PIOs
The MIA-M10Q supports communication over UART and I2C interfaces for communication with
a host CPU. Each protocol can be enabled on several interfaces at the same time with individual
settings for, for example, baud rate, message rates, and so on. In MIA-M10Q, several protocols can
be enabled on a single interface at the same time.
2.3.1 UART
The MIA-M10Q supports a Universal Asynchronous Receiver/Transmitter (UART) port consisting of
an RX and a TX line. The UART can be used as a host interface which supports a configurable baud
rate and protocol selection.
Neither handshaking signals nor hardware flow control signals are supported.
The UART baud rate can be configured for selected speeds; different rates for transmission and
reception are not supported.
The UART RX interface will be disabled when more than 100 frame errors are detected
during a one-second period. This can happen if the wrong baud rate is used or the UART RX
pin is grounded. An error message appears when the UART RX interface is re-enabled at the
end of the one-second period.

Table 13: Possible UART interface configurations
The default baud rate is 38400 baud. Using a lower baud rate may cause buffering
problems.
If the amount of data enabled is too much for a certain interface's bandwidth (for example baud
rate of all UBX messages output is 9600 baud), the buffer will fill up. Once the buffer space is
exceeded, new messages to be sent will be dropped. To prevent message loss, the baud rate and
