Bluetooth mesh networking enables many-to-many (m:m) device communications and is optimized for creating large-scale device networks. It is ideally suited for building automation, sensor network, asset tracking, and other IoT solutions that require tens, hundreds or thousands of devices to communicate with one another. SIG certification tests are done using the PTS (Profile Tuning Suite) dongle.

We have tested on low power SOC with integrated bluetooth and Zigbee connectivity which help customers develop low bandwidth IOT based products and services like Smart devices/sensor networks with power efficiency.It enables BLE with Mesh network technology using Nimble and Zephr stack.

Brief Overview.

The project is about AMI(Advance metering Infrastructure) based smart meters in which there is two-way communication between Smart meters and Utility Operators. Smart Utility meters are used for automatic collection of multiple intervals of billing data in engineering units from households to billing stations in a secured manner.The two-way communication is achieved by RF based mesh networks which consists of endpoints, repeaters, access points etc. Our team is involved in testing smart utility meters related to Water, Gas and Energy with different network devices using RF based proprietary mesh networking protocol.

The device includes:

  • Battery powered Smart Meters
  • Continuous powered Smart Meters

Our expertise in Test Areas:

  • Testing network discovery,joining the network and acquiring network identification.
  • Testing commands and responses between Smart meters and Access points in a lab environment.
  • Testing APIs at different levels (MAC layer/Network Layer/Application Layer).
  • Testing different topologies ( Mesh/Star/String of Pearls).
  • Testing of different security protocols between devices(Network Secure registration using digital certificates/Encryption/Authentication/ Authorization between network entities)
  • Billing meter data collection by Collection servers
  • Over the air multicast Firmware Upgrade and activation of firmware.
  • Handoff scenarios between two parents.
  • Time Synchronization between different devices and networks
  • Testing Network loss and PAN migrations scenarios
  • Test scenarios related to short duty cycle, long duty cycle and Regulatory duty cycle.
  • Link evaluation testing between nodes via applicable medium.

Deep testing is done to validate below features

  • Network stability
  • Network performance
  • Correct functioning of algorithms
  • Correct channel hopping
  • Synchronization
  • Crystal Drift compensation
  • Busy lists
  • Duplicate detection
  • Duty Cycle Regulation
