WiFi Lora 32 v4 -100 rssi <1m

Hello,
I have two LoRa Wifi 32 v4 and am running the pinpong example code. The boards are less than a Meter apart and have the shippped antennas attached. Why is the measured rssi between -100 and -120 while the SNR is around 0? When I increase the distnace to across the room, the connection even braks. I need this to work for a project.

You give too little information about your problem to give you advice.
The examples given work and you must adapt them to your problem.
For example, with only 3db in transmission I have an RSSI of -48dbm at 500m with transmitter and receiver in view
