iSXblue/SXBlue II GNSS Series Technical Reference Manual

source, the output will remain submeter for the next 30-40 minutes. See chapter 2 for more information.
For RTK operation, the receiver will maintain a fixed solution for 60 seconds after losing the RTK
source; then it will “float” for an extra 2 minutes and finally will default to the next available source of
differential correction available (L-Band, SBAS, None, etc).
The receiver is set to switch from 3D mode to 2D mode when there are less than 4 satellites or when the
PDOP value exceeds 10.5. It is usually up to the user software to allow or restrict 2D mode operation, but
this setting can be changed on the receiver ($JALT command).
The satellite elevation mask is set to 10 degrees by default. All satellites below this value will not be used
in the solution.
For the various Modes listed in the table, please refer to Chapter 4 for more information.
SBAS tracking is set to Automatic (see the $JWAASPRN command in chapter 4) and the number of
decimal digits used (in the coordinates of the GGA sentence for example) is set to 7 (see the $JNP
sentence)
1.3.2 Configuring Bluetooth Communication
There are many Bluetooth drivers available on the market today for PDA’s (using Pocket PC, Windows
Mobile, iPad/iPhone or Android operating systems), and for regular computers (laptop, tablet PC’s, etc.)
with standard Microsoft Windows, Apple iOS and Android operating systems.
Even though the setup procedure will be slightly different for each of them especially for the Bluetooth
communication on Apple iOS devices, the basics remain the same on Windows or Android. The two
major steps are: discovering a Bluetooth device and assigning a communication port number to the
discovered device. The data collection software will then call the assigned port number to receive the data
from the iSXBlue/SXBlue II GNSS.
In this section, we will give some examples of setting up Bluetooth communication with various PDA and
computer drivers. One key element to remember is that the iSXblue/SXBlue II GNSS does not require
any password (often called pairing, secure connection, authentication, passkey, passcode, etc). This
feature must be disabled in the options of the driver you are using. Should a passkey be mandatory with
the Bluetooth stack on your device, please use the following:
Bluetooth Passkey: “12345678”
Note – The iSXBlue/SXBlue II Series does not require any password/passkey for secure connection.
This feature can be disabled in the driver configuration of your PDA/Computer. A passkey of
“12345678” has been programmed in the receivers in case a Bluetooth driver absolutely requires a
secure connection.
