NEO-F10N - Integration manual
2.1 Basic receiver configuration
This section summarizes the most commonly used, basic receiver configurations.
2.1.1 Basic hardware configuration
The NEO-F10N receiver is configured with the default settings during the module production. The
receiver starts up and is fully operational as soon as proper power supply, communication interfaces
and antenna signal from the host application device are connected.
2.1.2 Internal LNA mode configuration
u-blox 10 receivers support three modes for the internal low-noise amplifier (LNA): normal gain, low
gain, and bypass mode. The NEO-F10N default is the normal mode. With a high-gain external active
antenna, the low gain or the bypass mode shall be used to save power.
The internal LNA mode can be configured at run time in the flash, BBR and RAM memory using the
configuration item CFG-HW-RF_LNA_MODE and applying a software reset by sending UBX-CFG-
RST message. For more information, refer to
The default gain mode is pre-configured in the receiver and does not require configuration in
production. The configuration strings for setting the internal LNA mode in the flash memory is given
in
Internal LNA mode

Table 3: Internal LNA mode configuration in the flash memory
Configuring the internal LNA mode in the flash memory:
1.
Power up the system.
2.
Test the communication interface by polling the UBX-MON-VER message.
3.
Send the configuration string in
.
4.
Power the receiver off and on or send UBX-CFG-RST message (the reset type must be set to a
hardware reset). The new internal LNA setting is applied at startup.
5.
Verify that the configuration item is correctly set by polling CFG-HW-RF_LNA_MODE at RAM
layer using the UBX-CFG-VALGET message.
6.
The configuration is completed.
2.1.3 GNSS signal configuration
NEO-F10N supports reception of GPS, Galileo, BeiDou and QZSS L1/L5 dual-band signals plus NavIC
L5 and SBAS L1. The default configuration is concurrent reception of GPS (L1C/A, L5), Galileo (E1-
B/C, E5a) and BeiDou (B1C, B2a) with SBAS enabled.
Each GNSS constellation can be enabled or disabled independently except for QZSS, which is
functional only with GPS. In addition to the configuration key for each constellation, there is a
configuration key for each signal supported by the firmware. For constellations with dual-band
support, it is not possible to disable one of the bands. Both bands must be enabled and disabled
at once. Alternatively, the CFG-SIGNAL-* configuration group for that constellation can be enabled
and disabled. For example, if CFG-SIGNAL-GPS_ENA is set to zero, the GPS constellation is disabled.
Unsupported combinations are rejected with a UBX-ACK-NAK message, and the warning "inv sig
cfg" is sent via UBX-INF and NMEA-TXT messages (if enabled).
