Hello, based on the motivation that IoT devices do not have many entropy sources available, and also on the fact that trusting in a single entropy source may be risky, I have researched on how to collect randomness for such devices, aiming to propose an additional source for them. The proposal is based on the Received Signal Strength Indicator using bluetooth technology. For those who are interested in: Github: https://github.com/AAGiron/Bluerandom Presentation: https://www.youtube.com/watch?v=iAKaKAmqCFo I also want to say thanks in advance to Emil Lenngren for his valuable comments here in this mailing list (back in 2019), and also to the Bluez community. -- Alexandre Giron
