in a project I am working on, I use Wemos D1 mini pro with external antenna (2dBi self-adhesive PCB antenna) and pure WiFiClient to send and receive data over WiFI. What I noticed is strange connecting behavior. I can't relate RSSI with connection success or failure:( Am I just trying to make a strange relationship or I am missing something? What I observed is that actually antenna position plays key role if connection will success or fail because it can happen that I have RSSI -75 or event -77 (50-46%) and connection is a success but also RSSI of -58 (80%) and antenna positioned wrong can make the connection fail. Anybody experienced similar behavior?
