A Novel Software Layer to Program Arduino over the Air using Bluetooth

Abstract

Programming over the air (POTA) is commonly used to update the firmware and configuration of a wireless sensor node without any physical contact with the node.We used this concept here to program the Arduino pro mini wirelessly over the Bluetooth link using HC-05 module.Bluetooth module only support UART traffic to communicate with slave devices. To implement POTA, a software layer is written for HC-05 module, this software layer makes HC-05 able to program Arduino pro mini over serial communication. The written software transfer data over the Bluetooth link to the slave hardware and then Arduino pro mini is programmed.
