HOME-GATEWAY FOR Connected Health – Medical Device
Firmware development for IOT product using BLG840F which act as a gateway to send data collected from BLE device over LTE to AWS IOT (Free RTOS, Fleet provisioning, shadow messages etc) using MQTT. Developed the full gateway firmware using NRFSDK and aws iot libraries. Also developed custom FOTA (OTA) download for both 9160 and 52840 chip. Code was initially developed for both nrf9160dk as well as nrf52840dk and later ported to BLG940F.Platform for development included Nordic BLE, AWS IOT SDK and Zephyr RTOS. Custom FOTA OTA library was custom developed so that firmware upgrade can be done to the second processor as well (nrf52840). Custom Flash data management library to address intermittent LTE connectivity and data integrity
