To face the nowadays challenges of including Internet of Things devices in production systems, to automate and simplify the collection of data, the study of transmissions and protocols is of paramount importance. By starting on two example boards and the Bluetooth Low Energy as chosen protocol, a testbench is defined to simplify and characterise the in-field system where they can be applied: a capping machine produced by AROL Closure Systems. The aim of this thesis work is to analyse and create an experiment where different boards can be used to decide which one has a better broadcast and test its limit conditions, with a structure that can be modular and adapted for different implementations.
