Introduction

The firmware in the AWS configuration gathers sensor data over BLE and sends the data to the cloud (AWS) via LTE-M (for Pinnacle 100 and MG100) or Ethernet (for BL5340).

One sensor that can be used is the BL654 Sensor Board. This sensor ships with the Pinnacle 100 development kit (DVK) and measures temperature, humidity, and pressure - alternatively the BL5340 ESS demo application can be loaded to a second BL5340 which provides the same service, this is available in the sample_apps_common/ess_demo folder as seen here and a pre-built image can be downloaded from here.

Another supported sensor is the BT510. It records temperature and movement. The BT510 can also be configured to detect a door opened/closed.

The Pinnacle 100/MG100/BL5340 device scans for the BL654 Sensor Board/ESS sensor and connects to the first one it finds. At the same time, the device gathers data for the BT510 sensors from advertisements without creating a connection. The demo supports up to one BL654 Sensor Board/ESS sensor and up to five BT510 sensors. The demo can be recompiled to remove support for either sensor.

Using the Pinnacle Connect mobile app, the user can provision the Pinnacle 100/MG100/BL5340 device to connect to AWS. Once connected to AWS, the device sends sensor data (if a sensor is found) to the cloud every 60 seconds. Once a BT510 is discovered and enabled via the web portal, its sensor data is reported. The details of the BT510 data reporting are detailed below.

MG100 Settings

Note: Only available if you are connected to an MG100.

All MG100 variants have an onboard accelerometer. It is currently configured to detect movement on the gateway and report that over BLE or to the cloud via the shadow. The MG100 application will send a notification when motion is detected and another notification 30 seconds after movement has stopped. Currently, no accelerometer parameters are configurable. Subsequent versions of the MG100 firmware will allow some configuration of the accelerometer via the shadow. This view shows the status of the motion sensor.

Power Settings

The power settings page displays the battery voltage and allows the user to reboot the modem. MG100 variants, 450-00038-K1 and 450-00054-K1 are equipped with a rechargeable Li-ion battery used for backup power when external power is lost. The battery will automatically start charging again once external power is restored and the the battery is not fully charged. The firmware monitors the battery voltage and temperature to provide remaining capacity left in the battery. This data is sent over BLE or cellular to report voltage and remaining battery capacity. The battery thresholds are defaulted to reasonable values, but they can be modified via BLE or the shadow if customization is desired. The threshold defaults are as follows. The lowest the battery is allowed to discharge to is 2.75V before the under-voltage protection hardware kicks in.

Battery Threshold 4 - 4200 mV
Battery Threshold 3 - 3800 mV
Battery Threshold 2 - 3400 mV
Battery Threshold 1 - 3000 mV

These thresholds are designed to provide approximately equal discharge time between thresholds 4-3 and 3-2. Below threshold 2, the amount of time left before the battery discharges completely, drops off quickly. This behavior can vary depending on conditions and battery health.

This view displays the battery information. Note the MG100 does not allow for measuring the voltage of the external power supply like the Pinnacle 100 DVK. That is why power supply voltage is always shown as -1 for MG100 devices.

LED Behavior

Pinnacle 100/MG100

The Blue LED blinks when the module is advertising and allowing another device to connect to and configure it. When a central device connects, the LED remains on. When advertising stops, the LED remains off. Button 1 (SW1) can be pressed to restart advertising.

The Green LED turns on when connected to AWS. When data is sent to AWS the LED turns off and then turns back on. When disconnected from AWS, the LED remains off.

The Red LED blinks when the device is searching for a cellular network. It remains on and does not blink when connected to a network. If there is an error with the SIM card or network registration, then the LED remains off.

Note: Before to version 3.x of the firmware, Red LED performed the Blue LED function. Blue LED performed the Green LED function. Green LED performed the Red LED function.

BL5340

There are 4 blue LEDs on the BL5340 development kit with buttons above them, the first LED is located on the left and last LED on the right.

The first blue LED blinks once a second when the BL5340 is advertising which allows a phone to connect to it. When a device connects to it, the LED remains on. When the BL5340 stops advertising, the LED remains off. Note that the button above the LED can be used to start the device advertising if it has stopped.

The second blue LED blinks once a second when the BL5340 is searching for a BL654/ESS sensor. When it finds a sensor and successfully connects to it, the LED remains on.

The third blue LED turns on when an ethernet cable is connected and remains off if no cable is detected.

The forth blue LED turns on when connected to AWS. When data is sent to AWS the LED turns off and then turns back on. When disconnected from AWS, the LED remains off.

My Own AWS Connection

If you wish to connect to your own AWS instance, See here for instructions.

Building the Firmware

Note: If using VS Code for development the build aws task can be used to easily build the firmware.

Note: The OOB demo integrates the Memfault SDK. See here for more details.

Issue these commands from the ble_gateway_firmware directory.

WARNING: If using windows, checkout code to a path of 12 characters or less to avoid build issues related to path length limits.

Build commands:

Note: [board] should be replaced with mg100, pinnacle_100_dvk or bl5340_dvk_cpuapp

# Linux and macOS

west build -b [board] -d ${PWD}/build/[board]/aws ${PWD}/app

# Windows

west build -b [board] -d %CD%\build\[board]\aws %CD%\app

After building the firmware, it can be flashed with the following command:

Note: [board] should be replaced with mg100, pinnacle_100_dvk or bl5340_dvk_cpuapp

west flash -d build/[board]/aws

west flash will program all images (mcuboot, app, network core) required to run the app.

Note: For the BL5340 the full firmware comprising of the application and mcuboot for the application core and Bluetooth stack and mcuboot for the network core will be flashed to the module. Note that if flashing fails, it might need to be performed by doing a recover which can be done by using the following command instead:

west flash --recover -d build/bl5340_dvk_cpuapp/aws
