  OSMOS-GROUP PARIS 16, France
  Jan - aujourd'hui

  • LIRIS-V3 Porject: OSMOS has developed a range of structural health monitoring solutions. Among them, they
  designed autonomous sensors called LIRIS, that are installed on key points of the structure to measure the effects
  of deformations, cracks, bearing conditions or external stresses. The main tasks that I have conducted are:
  – Maintaining the LIRIS_V3 source code: bug fix and new features implementation.
  – Implement and test the LIRIS-420mA module.
  – Integrate the crack-Meter module.
  – Integrate an SMS module.
  – Implement low lovel driver for ADC and DAC based on SPI interface.
  – Implement a driver for the Lora-Grove to synchronize LIRIS for OSMOS WIM+D uses case project
  – Programming Languages used : C
  – Software environment: Keil, JLink, GitLab
  – Hardware environment: nRF52832 cortex M4
  • LIRIS LTE-M/Nb-iot: In order to reinforce the aspect of autonomous sensors, OSMOS has developed an extension
  board that host an LWM2M client module which uses LTE-M/Nb-iot technologies to communicate with the server.
  The main tasks that I have conducted are as follow:
  – Participate in specifications elaboration.
  – Definition of the software architecture.
  – Define the project skeleton based on zephyr OS project.
  – Implement driver to communicate with the LIRIS-V3 via asynchronous interface.
  – Implement the LWM2M client side with customized objects.
  – Reduce power consumption with respect to the specifications.
  – Implement a flusk based micro-server with python.
  – Programming Languages used : C, python, Makefile

  – Software environment: Zephyr, MC-UBOOT, Arm-GCC, GDB, JLink, GitLab – Hardware environment: nRF9160 cortex M33
