Ola Alexandre,
Que coincidência ver alguem da UTFPR por aqui, fiz meu mestrado ai em
2003, muito legal o seu trabalho. So por curiosidade, voce chegou a
usar o BT_HCI_CMD_LE_RAND como fonte de entropia? No Zephyr
(https://www.zephyrproject.org/) agente usa bastante porque o
controlador pode usar o sinal de interferência direto da camada do
radio, abaixo da interface HCI, e segundo o pessoal da Nordic tem uma
qualidade bem maior do que por exemplo RSSI porque nao depende da
quantidade de dispositivos em volta.
