How to sniff a BLE communication and decode it: Reverse Engineering
Intercept Bluetooth communication of smart gadgets (for example fitness devices) is a nice idea to have cheap BT sensor nodes. I will explain how to sniff and decode your Bluetooth Low Energy Data from your sensors. [Read more…] about How to sniff a BLE communication and decode it: Reverse Engineering
Autocorrelation and Crosscorrelation calculation in LabView
A LabView sketch was used to simulate the stochastic signals and evaluate the functionality of the autocorrelation and cross-correlation function. Also the spectral power density was calculated.
