$250-750 USD

Paid on delivery
I am looking for a freelancer to develop the firmware for a fairly simple IOT device. The device uses Nordic nRF52832 so familiarity in programming this chip is important. It also consists of 2 sensors, buttons, RGB light and power components. The key functions to be programmed are collecting and storing data from the sensors and button pushes, a few simple calculations based on the data, linking with mobile app and sending data through BLE, programming the light to shine when the hardware is in certain states (charging, button pushed, etc). I can provide exact specifications to chosen freelancer. Key skill will be minimizing power consumption so can maximize battery life with small battery.
