1. Worked on flashing different cores on the Arm cortex (CM4, CM7, bootloader) using JLINK and CLI. 2. Worked on validation of OTA(over the air) firmware upgrade for different cores i.e CM4,CM7,CM4boot. 3. Worked on the development of python script to read sensor data and check that all are correctly aligned. 4. Integration of all the developed Python scripts into the robot test framework to automatically run basic test cases on a daily basis using Jenkins CI/CD pipeline script. 5. Hands-on experience in developing Jenkins CI/CD pipeline script to run automated tests and publish a report to the stakeholders. 6. Worked on validation of SD card used to store camera image as well as audio recording. 7. Developed test cases for BLE, Camera, Audio, Sensors, Network, Battery, GPS and OTA module. 8. Hands-on experience in testing audio-related modules for rain detection 9. Hands-on experience in validating file system modules for ssd as well as sd card. 10. Worked on validation of disdrometer data on different sampling frequencies i.e 150,350,500,700Hz 11. Worked on flashing and debugging of Microcontroller (SAME54, SAMD21) and verified board behavior. 12. Tested IPC and UART communication between these two boards at different threshold. 13. Worked on automation of VP portal for our project by using selenium python scripting. 14. Worked on addition of new file for test framework and made necessary code changes for supporting these newly added files and building it successfully to flash the image on board. 15. Verified all the functionality of sensors (tilt, pressure, temp, humidity) used in SAMD21 board. 16. Worked on Taking Test input through device COM port and passing it to the device to run test cases. 17. Tested NFC communication between the Gateway and Tag device used in the project. 18. Worked and fixed hard fault issue on the Lora 1276 board along with EVK board. 19. Worked on configuration of Tplink devices to use ethernet connectivity for SAMD21 board. 20. Worked on testing of Restful web services API using postman API. 21. Worked on validation of cloud connector protocol like MQTT, GRPC, EGRPC along with Lora Server. 22.Implemented radio related AT command for the modem used to integrate WSN server and client. 23.Worked on compilation issue after integrating of newer kernel version on top of older version. 24. Developed Robot framework python-based script to check the deployment status,sensor data of the device. 25. Validated CLI used in device to get the different sensor data, reset, version, stats, chunks etc.
