Step-by-step initialize measurement engine

Initializing the measurement is mainly useful for special tracking applications. E.g. if unhealthy satellites are forced to healthy and then
set back to automatic health setting, it is recommended to initialize the measurement. Satellites with bad health may transmit incorrect
almanacs and ephemeris.
Step Description
Open the receiver's web interface in a browser window by typing in the receivers IP or hostname.
1
Go to the Receiver setup / Tools page

Press the Initialize measurement engine
The receiver will stop tracking satellites and lose the navigated position. It takes several minutes for the
receiver to start tracking again and regain a navigated position.

How to use Bluetooth on the GR25/50

Background Information

When the Bluetooth device on the GR25/50 is enabled, it can be used in two ways: either as an additional serial port or like a TCP/IP
connection to a local (Ad Hoc) network.
The GR25/50 can be ordererd as a Bluetooth or a WLAN version. Bluetooth functionality can only be used
on GR25/50 with the Bluetooth radio installed.
The Bluetooth name that the GR25/50 is detected with is always equal to the hostname configured in the
Receiver setup: Network connections, Ethernet tab.

Bluetooth serial connection

The Bluetooth connection can be used to provide an additional serial port to be configured on the receiver. To configure a data stream
via Bluetooth serial port, select Bluetooth from the list of available connection types.
Once the data stream is configured, external devices will be able to detect the serial connection on the Bluetooth port and connect to the
data stream.

Bluetooth Ad Hoc network

The Bluetooth connection can be used to establish a subnet in which the receiver can be accessed like via a TCP/IP connection. This
would allow web interface access, data streaming via TCP/IP ports, FTP push or GNSS Spider access within the subnet.
In order to use this connection, the user must establish a Bluetooth network on their PC and assign the IP address 192.168.253.x and
subnet mask 255.255.255.0. Following the pairing of the Bluetooth device, the GR25/50 receiver can be accessed via the IP address
192.168.253.2.
When the Bluetooth device is disabled, all configured connections/data streams will still be enabled but not
usable, as no connection to the Bluetooth ports will be possible.
