I’m interested in Wi-Fi triangulation using the Wi-Fi notecard. I’m trying to grasp it, and a question a rise. For my understand the Wi-Fi notecard already has the triangulation enable. So I just need to send the Wi-Fi access point (AP) scan related to the AT+CWLAP command. At an movement detected it the latitude and longitude is displayed in an json format. What I’m not grasp is how the latitude and longitude are determined, if with RSSI only the distance to the Wi-Fi AP can be calculated ?
Thank you very much,
