I'm experienced in the embedded system development stream especially in BLE-based product designing and implementation on nordic based controllers like nrf52832, nrf52840, and nrf52810, etc. I can do the Hardware and firmware design and development Changes or updating the existing firmware. Firmware development using Segger, Arduino IDE, IAR Workbench, and Keil. BLE based application development, the addition of BLE gatt services and communication to mobile phone. Mesh and central peripheral BLE application developments. OTA updates through bootloader settings in nrf controllers Interfacing of multiple sensors with the controllers. IoT-based product development. We have worked on end to end based multiple IoT applications that can get data from some node and communicate through a medium like Lora Wan or BLE or Wifi and send data to the cloud. We can choose medium according to application requirments. We have done work on multiple controllers like Arduino, ESP32, ESP8086, Nordic nrf52 DK, Sparkfun boards with nrf52 chips support like breakout board and itsybitsy boards.
