BAPI 50387 Wireless Bluetooth Low Energy Gateway
Product Information
The Wireless Bluetooth Low Energy Gateway is a device that provides data via MQTT to the cloud. It supports up to 32 sensors that can be remotely configured through the gateway and BAPI’s WAM user interface. The gateway receives data from one or more sensors and transfers it to the cloud using MQTT through your local Wi-Fi connection. In case of communication loss, sensors retain readings in their onboard memory and transmit them once communication is re-established. Please note that a WAM subscription is required to view sensor data and adjust sensor settings.
Overview
- Gateway provides data via MQTT to the cloud
- Each gateway supports up to 32 sensors that can be configured 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 configured remotely via the gateway and BAPI’s WAM user interface.
The gateway sends a confirmation signal to each sensor upon a successful reception. If the sensor doesn’t receive this confirmation, 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 3.
Powering Up and Connecting the Gateway
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 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 flashing rapidly (See Fig 1).
Connect
NOTE: If the gateway was previously paired to another Wi-Fi access point,
you will need to reset the gateway. This will erase the Wi-Fi credentials and
any previous sensor pairings. (See
“Resetting the Gateway” on pg 3.)
Use your phone, tablet or laptop to follow the steps below.
-
Open up the Wi-Fi settings on your mobile device or computer and select “bapi_gateway” from the list of available networks. If your device asks for a password or network security key, enter “changebp”.
-
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 SoftAP screen will come up (Fig 2). -
Click on the desired Wi-Fi access point (SSID) from the “Scan List” and enter the password for that network (Fig 3). Click Connect.
-
At this point, the various LEDs will flash for 15-30 seconds. The connection is complete when the green “Power” LED is the only LED that is flashing. You can close your web browser window. 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.
Note: Should the gateway lose power or connection, it will attempt to rejoin the network on its own.
Pairing Sensors with the Gateway
- Select the sensor that you wish to pair to the gateway. Apply power to the sensor. See its manual for detailed instructions.
- Press and hold the “Service” button on the gateway until the blue “Bluetooth” LED begins to flash (about 3 seconds). Then release the “Service” button to enter pairing mode. NOTE: When in pairing mode, the blue “Bluetooth” LED will continue to flash providing the user a 20 second window to pair the sensor with the gateway.
- Press 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. At that point, the gateway will leave pairing mode and the blue “Bluetooth” LED will go out. The blue “Bluetooth” LED will then flash each time a sensor communicates with the gateway. Repeat this process for all sensors. The gateway and sensor pairings are now complete.
The figures above are shown for reference. Refer to the instructions document for your specific sensor for the location of the “Service” button and “Service” LED.
Mounting
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.
LED Operation
Green “Power” LED
- Slow Blink = Normal Operation. Gateway is connected to the Wi-Fi network. Fast Blink = 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 = Gateway is in pairing mode and waiting to be paired with a sensor.
- Amber “Wi-Fi” LED
- Slow Blink = Gateway is not connected to the Wi-Fi network.
- Fast Blink = Gateway is attempting to connect to the Wi-Fi network.
(Green “Power” LED will be on solid during this time.)
Note: The gateway shuts off 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” on pg 3 for more information.)
Resetting the Gateway
If the amber “Wi-Fi” LED doesn’t go out and continues to blink, the
connection has failed and a reset is required. Press and hold the service
button on the gateway for about 30 seconds. During this time, the various LEDs
will flash. The reset is complete when the green “Power” LED is the only LED
that is flashing. Follow the “Powering Up and Connecting the Gateway”
instructions on pg 1 to re-connect the gateway.
Resetting a Sensor
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 flash slowly, then begin flashing rapidly. When the rapid
flashing stops, the reset is complete. The sensor can now be paired to a new
gateway. To re-pair to the same gateway, you must reset the gateway.
Sensor Memory Mode
The gateway sends a confirmation 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.
WAM and the WAM Website
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 for the sensor.
Contact you BAPI representative to subscribe and receive your login
credentials.
