To develop a booster pack we are using an industrial grade open source hardware called MangOH Red designed to address common IoT pain points and deliver 90% of our prototype out-of-the-box so we can focus our time and resources building the next killer IoT application and bringing our products to market sooner. We are using a CF3 module of WP series (wp7502), which is a 4G module, manufactured by a sierra wireless company. This module is built using a Legato platform and uses its own APIs to operate and execute. Basically, nowadays IoT plays important role in the society hence this helps for quick prototyping and provides an easy way for requirements of the Internet of Things. This concept mainly involves the implementation of serial communication between client and server using MangOH and MSP430 [11] [12]. Keywords: APIs, MSP430, GSM,CF3, LP, IoT. I. INTRODUCTION The microcontroller is a computer system on a chip that does a job. It contains an integrated processor, memory, and programmable input output peripherals which are used to interact with chips. MSP430 is one of the most important aspects of the hardware. The MSP430 is the simplest microcontroller in TI. It is a product of Texas Instruments. The MSP430 was introduced in the late 1990s, although its ancestry goes back to the 4-bit TSS400. In summary, it is a particularly straight forward 16-bit processor with a Von- Neumann architecture, designed for low-power applications. The CPU is often described as a reduced instruction set computer (RISC) but this is if unimportant and is considered in the section “Reflections on the CPU and Instruction Set”. Both the address and data buses are 16 bits wide. The registers in the CPU are also all 16 bits wide and can be used interchangeably for either data or addresses. This makes the MSP430 simpler than an 8-bit processor with 16-bit addresses [1] [2]. The figure1 shows a block diagram of the MSP430. The main features are  On the left are the CPU and its supporting hardware, including the clock generator. The emulation, JTAG interface, and Spy-Bi-Wire are used to communicate with a desktop computer when downloading a program and for debugging.  The main blocks are linked by the memory address bus (MAB) and memory data bus (MDB).  These devices have flash memory and 128 bytes of RAM.
