Introduction
This User’s Manual describes installation and setup of the Messenger-BLE product.
Throughout this document, Messenger-BLE and Messenger are used interchangeably.
The Messenger is a complete monitoring, alarm notification, and telemetry platform.
The intended markets include (but not limited to) water/wastewater utility, off-road
heavy construction equipment, on-road semi-trucks, oil and gas, and standby power
generators. It supports monitoring of data values from on-board physical IO, the J1939
SAE engine bus topology, the industry standard Modbus RTU serial protocol, and
support of custom serial communications to external devices.
Features
The hardware feature set of this platform includes:
ARM 32-bit Cortex -M4 Core w/FPU
2 MB of on-board FLASH memory, 8MB of external FLASH
640kB of on-board SRAM memory, 512kB of external battery-backed SRAM
Real Time Clock (battery-backed)
2 Serial Ports (RS485 only)
4 Digital Inputs (user configurable for voltage or grounded input)
3 Digital Outputs (open-collector transistor closures to ground)
3 Analog Inputs (12-bit, user configurable for V or I input)
1 CAN Interface, compliant to Bosch CAN Protocol v2.0 A/B
Cellular modem, HSPA (3G) or LTE (4G)
GPS receiver, providing location services using multiple GNSS constellations
3-axis Accelerometer
SuperCap for brown-out protection
Separate Bluetooth engine for wireless connection to hand-held devices
Deutsch EEC automotive grade enclosure

1 Description
1.1 Capabilities
The Messenger is a highly configurable platform for remote monitoring and control
applications. Some of the capabilities are listed below.
virtual real-time transfer of monitored conditions
local computations from monitored conditions
time stamping of monitored data and events
battery backed historical data/event buffers
automatic monitoring of max/min for analog values
continuous monitoring of J1939 bus data
event and data logging
telemetry of monitored conditions to server applications via cellular
OTA programming and diagnostics, cellular and Bluetooth
SMS messages sent on monitored conditions
parameter setting via SMS messages
1.2 Monitoring
All monitored values can be transmitted via cellular to a host server of the customer’s
choosing. Monitored values are transmitted based on time or notification events.
Notification events are based on rules set by the user and each event can generate an
immediate report. Telemetry includes cellular connectivity and GPS for asset location.
Monitored data values are mapped to fixed channels in the Messenger. A channel
defines a set of attributes for the monitored data for doing calculations, alarm
detection, data formatting, and reporting.
For example, RPM is fixed to channel 52. For channel 52, the user can set limits on
RPM for notification when RPM gets too high, and how to report the RPM values to a
host server.
Table 4.1 provides a description of all the pre-defined channels and channel numbers.
Appendix A identifies the set of SAE defined PGNs and SPNs for data values being read
from the engine bus. User can also configure for other engine values as needed.
1.3 Host Server Communications
The Messenger utilizes a proprietary protocol to send notifications and to receive OTA
commands from a host server. Each notification sent typically consists of location,
8

User Guide
date/time, an event code, and associated data. An event code provides a unique
identifier to indicate the reason that notification is being sent – e.g. normal scheduled
update or an engine diagnostic message received. A description of the protocol,
format of messages, and definition of event codes is available on request (reference
protocol document “M09-PRTCLxxx”).
Some of the conditions on which notifications can be sent to the host server are listed
below:
Any monitored value exceeding a pre-defined or user-defined limit
Any diagnostic message received from the engine bus
A digital input changing state (on/off)
A digital output changing state (on/off)
An analog input transitioning into a warning or alarm region
An analog input changing by user defined delta
A scheduled/periodic update
End of day
System faults
SMS text commands from a user or host server
Power on or reset
1.3.1 Event Codes
Every message sent by the Messenger to a host-based server application is triggered
by an event. The event generates a message and the message contains an Event Code.
The Event Code uniquely identifies to the server the reason the message is being sent.
Some of the messages generated contain data, others serve as just notification that a
particular event has occurred. Protocol document “M09-PRTCLxxx” contains a list of all
event codes.
1.3.2 Positive Acknowledgement
The Messenger can be configured to require a message acknowledgement from the
host server or to send once and forget. Message acknowledgement provides a
verifiable mechanism that a message was delivered, even during poor network
conditions.
This parameter setting can be found in the CELL configuration.
1.3.3 Store and Forward Data Queue
There are several scenarios where a message may not be deliverable – network down,
host server down, poor connectivity to name a few. In the event that a message
cannot be delivered, it is stored in memory and is continually re-sent until properly

MessengerBLE
User Guide
acknowledged. This store and forward memory is non-volatile and remains intact
during power off.
1.3.4 Real-Time Clock (RTC)
The RTC is used to timestamp data records and events. All messages sent to the host
server contain a timestamp to provide a chronology of data/events to the end user.
This timestamp is UTC time. All timestamps viewed from the debug menu are local
time based on the configured time zone.
The RTC is battery backed to provide time keeping during power off. If the RTC is
configured to be automatically set, the Messenger will set time after every power on
and perform a time check every midnight. If the RTC time differs from actual time by
more than 30 seconds, the RTC time will be adjusted.
The RTC can be set in one of the following ways:
Method Description
Automatic
via Cell
This is the default setting. The
Messenger will set the RTC from an
internet NIST time server.
Automatic
via GPS
The Messenger will set the RTC from
the date/time read from the GPS
module.
Manually Set the time via the Debug port
through the Maintenance menu.
OTA/SMS
The RTC is set from an OTA config
command or an SMS config
command.
Configuration settings are available to define how the RTC is set.
1.3.5 Packaging
The Messenger is packaged in an automotive grade Deutsch enclosure. There are 2
antenna connections, one SMA connection for the GPS and one SMA-RP (reverse
polarity) connection for cellular. The enclosure end-cap provides 2 circular M12, 8-pin
connectors for power and IO.
