ESP 32 BLE Signal Strenght RSSI
Posted: Wed Jun 01, 2022 4:40 pm
I'm testing an ESP Wroom 32 as BLE device (BLE server) using Arduino IDE.
Very close to the ESP32 ( 20-30 cm) the signal strenght - RSSI value is about -55 -60 dBm that is good. Already at 2 meters (without any obstacle) the signal strenght drop to -70 - 75 dBm (that is accettable). But at more than 4-5 meters the signal goes at - 90 dBm that is too low signal. Is there any way to improve this behaviour?
Any idea?
