The BLE standard specifies a wide range of configurable parameter values that determine the discovery process and need to be set according to the particular application requirements. Many previous works have been addressed to investigate the discovery process through analytical and simulation models, according to the ideal specification of the standard. However, measurements show that additional scanning gaps appear in the scanning process, which reduce the discovery capabilities. These gaps have been identified in all of the analyzed devices and respond to both regular patterns and variable events associated with the decoding process. We have demonstrated that these non-idealities, which are not taken into account in other studies, have a severe impact on the discovery process performance. Extensive performance evaluation for a varying number of devices and feasible parameter combinations has been done by comparing simulations and experimental measurements. This work also includes a simple mathematical model that closely matches both the standard implementation and the different chipset peculiarities for any possible parameter value specified in the standard and for any number of simultaneous advertising devices under scanner coverage. info:eu-repo/grantAgreement/ES/MINECO/TEC2014-58341-C4-2-R info:eu-repo/grantAgreement/ES/MINECO/TEC2014-60258-C2-2-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.475 2017 CHEMISTRY, ANALYTICAL 30 / 80 = 0.375 2017 Q2 T2 INSTRUMENTS & INSTRUMENTATION 16 / 61 = 0.262 2017 Q2 T1 ELECTROCHEMISTRY 15 / 28 = 0.536 2017 Q3 T2 0.584 2017 Analytical Chemistry 2017 Q2 Atomic and Molecular Physics, and Optics 2017 Q2 Medicine (miscellaneous) 2017 Q2 Electrical and Electronic Engineering 2017 Q2 Instrumentation 2017 Q2 Biochemistry 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-0299-0859 Hernández, Ángela Universidad de Zaragoza Valenzuela, José Luis (orcid)0000-0003-2664-6339 Valdovinos, Antonio Universidad de Zaragoza 5008 560 Universidad de Zaragoza Dpto.
