Power Up of the Gateway
Attach the provided antennas. Power the unit by inserting the
included Micro USB cable into the “Micro USB” power port or
by connecting a PoE-enabled cable to the PoE Port. Note: The
ethernet port does not have network capabilities at present but is
only used for PoE.
Upon power-up, the green “Power” LED will be blinking rapidly
(on and o󰀨 about twice per second). This indicates that the
gateway is in SoftAP mode waiting for you to complete the
connection process. If the green “Power” LED is blinking slowly
(on for a second and o󰀨 for a second), then the gateway will
need to be reset to SoftAP mode. See “Resetting the Gateway
to SoftAP Mode” on pg 3.
Connecting the Gateway
Use your phone, tablet or computer to follow the steps below.
1. With the gateway in SoftAP mode as described above, open
up the Wi-Fi settings on your mobile device or computer and
select “bapi_gateway” from the list of available networks
(Fig 2). If your device asks for a password or network security
key, enter “changebp”.
2. Using the same device, open a web browser and enter
“10.10.0.1” into the address bar, not the search bar. The
gateway’s list of available Wi-Fi Networks will come up (Fig 3).
3. Click on the desired Wi-Fi network from the “Scan List” and
enter the password for that network (Fig 4). Click Connect.
4. During the connection process, the various LEDs will blink
for 15 to 20 seconds. The connection is complete when the
green “Power” LED is blinking slowly (on for a second, off for
a second) and is the only LED on. You can now close your
web browser window. (Note: If the amber “Wi-Fi” LED doesn’t
go out and continues to blink, the connection has failed. See
“Resetting the Gateway” on pg 3.)
Powering Up and Connecting the Gateway
● Gateway provides data via MQTT to the cloud
● Each gateway supports up to 32 sensors that can be congured remotely via the
gateway and BAPI’s WAM user interface
BAPI’s gateway receives the data from one or more sensors and provides the
data to the cloud via MQTT using your local Wi-Fi connection. Sensors can be
congured remotely via the gateway and BAPI’s WAM user interface.
The gateway sends a conrmation signal to each sensor upon a successful
reception. If the sensor doesn’t receive this conrmation, then the sensor retains
the readings in its onboard memory and transmits them once communication is
re-established.
Note: A WAM subscription is necessary to view sensor data and adjust
sensor settings. See “WAM and the WAM Website” on pg 4.

Pairing Sensors with the Gateway
1. Select the sensor that you wish to pair to
the gateway. Apply power to the sensor.
See its manual for detailed instructions.
2. Press and hold the “Service” button on the
gateway until the blue “Bluetooth” LED
begins to ash (about 3 seconds). Then
release the “Service” button to enter pairing
mode. NOTE: When in pairing mode, the
blue “Bluetooth” LED will continue to ash
providing the user a 20 second window to
pair the sensor with the gateway.
3. Press and release the “Service” button
on the sensor to pair it with the gateway.
When the sensor is successfully paired,
the sensor will flash its green “Service”
LED 3 times and the blue “Bluetooth”
LED on the gateway will go out. The blue
“Bluetooth” LED will then flash each time
a sensor communicates with the gateway.
The sensor will now appear as one of
the devices for that gateway on the WAM
website.

5. Pair one of your sensors with the gateway as described in the next section “Pairing
Sensors with the Gateway” and then return to Step 6. At least one sensor MUST
be paired with the gateway before going to the next step.
6. Reconnect your phone, tablet or computer to your original Wi-Fi or ethernet
network and open the BAPI WAM website (https://wamstage.bapihvac.com). Enter
the Username and Password for your WAM subscription. (A WAM subscription is
required to view your sensor data. If you do not have a subscription, contact your
BAPI representative to subscribe and receive your login credentials.)
7. Click the “Enter Serial Number” link, or
click on the green “+” icon across from the
word “Gateway” in the left menu bar (Fig 6),
to open the “Enter Gateway Serial Number”
window (Fig 7).
8. Enter the gateway serial number from the
label on the side of the unit and click “Add
Gateway”. The gateway will not appear in
the gateway menu on the left side of the
WAM screen and the sensors will appear in
the main window.
Note: If the gateway
loses power or
connection, it will
attempt to rejoin
the network on its
own. If the automatic
reconnection fails,
follow the steps
above to reconnect.

The gateway includes a removable keyhole type base plate that allows
you to mount the gateway in a vertical or horizontal position. Remove
the base plate from the gateway and use it to mark the mounting hole
locations on your mounting surface. If mounting in a vertical position,
ensure that the arrows in the base plate and gateway are pointing up.
Mount the base plate to the surface. Then slide the gateway on to the
base plate.
NOTE ON ANTENNA: The unit must use the supplied antennas. Do
not replace the antennas with other antennas. Using antennas other
than the ones provided by BAPI may violate FCC regulations.

GREEN “POWER” LED
• Slow Blink (one second on, one second o󰀨)
Normal Operation. Gateway is connected to the Wi-Fi network.
• Fast Blink (on and o󰀨 twice per second)
Gateway is in SoftAP mode waiting for you to complete the connection process.
• Constant On
Gateway is locked up, requiring a physical reset by unplugging and then
plugging back in the Micro USB power supply or PoE source.
BLUE “BLUETOOTH” LED
• Periodic Blink
Data transmission received from a paired sensor.
• Fast Blink (on and o󰀨 three times a second)
Gateway is in pairing mode and waiting to be paired with a sensor.
AMBER “WI-FI” LED
• Slow Blink (one second on, one second o󰀨)
Gateway is not connected to the Wi-Fi network.

LED Operation
Note: The gateway shuts o󰀨
the Bluetooth Low Energy
radio when a Wi-Fi connection
is lost, forcing the sensors
into memory mode until the
connection is re-established.
(See “Sensor Memory Mode”
below for more information.)
Resetting the Gateway to SoftAP Mode
Follow this procedure to reset the gateway to SoftAP mode. This will erase the Wi-Fi credentials and any previous
sensor pairings. Press and hold the “Service” button on the gateway for at least 30 seconds. During the first 20
seconds, the green and blue LEDs will blink rapidly and then the green LED will blink rapidly by itself for about 5
seconds, and then all three LEDs will blink rapidly for about a second. When the green LED is blinking rapidly by itself
(on and off about twice a second), the reset is complete and you can release the “Service” button. The gateway is now
in SoftAP mode and ready for connecting to the WiFi network as described in the “Powering Up and Connecting the
Gateway” instructions on pg 1.
Note: If the green LED is blinking slowly (on for a second and off for a second), rather than rapidly, then the reset did
not complete. Repeat the reset procedure making sure to keep the “Service” button pressed throughout the entire
process described above.

A BAPI Wireless Asset Monitoring (WAM) subscription is necessary to view
sensor data and adjust sensor settings. WAM is a cloud application that
lets you monitor all of your sensor data and trends via an internet browser
on your computer or smart device. WAM also lets you adjust settings for the
sensors and receive alerts if the readings go above or below the user-defined
thresholds.
Contact your BAPI representative to subscribe and receive your login
credentials.
The gateway sends a conrmation signal to each sensor upon a successful reception. If communication is lost between
the sensor and the gateway, the sensor will enter “Memory Mode” and begin storing its data in its onboard memory.
Each sensor retains up to 16,000 readings. Once communication with the gateway is re-established, the sensor will
begin sending its stored data to the gateway. The sensor will send 9 past values and 1 current value at each transmit
interval until all the stored data is transmitted. Temporarily shortening the transmit interval will allow the sensor to more
quickly clear any stored readings.
Sensor Memory Mode
Sensors remain paired to the gateway when power is interrupted or the batteries are removed. To break the bonds
between them, the sensors need to be reset. To do this, press and hold the “Service” button on the sensor for about
30 seconds. During those 30 seconds, the green LED will be off for about 5 seconds, then blink slowly for about 10
seconds and then blink rapidly for about 15 seconds. When the rapid blinking stops and the LED goes out completely,
the reset is complete and you can release the “Service” button. The sensor can now be paired to a new gateway. To
re-pair to the same gateway, you must reset the gateway as described in the section above.
