I’ve just bought two LILYGO TTGO LoRa32 V2.1_1.6 433MHz boards (marked “T3_V1.6.1 20210104”), and installed OpenMQTTGateway v1.4.0 with rtl_433, but am lucky to receive one weather station message per day. I know there are transmissions to receive, because I have an SDR 433MHz dongle plugged into a Raspberry Pi that receives them. I’ve installed the pre-built “lilygo-rtl_433” web upload installer of OpenMQTTGateway v1.4.0.
Is it significant that the log file reports “Average RSSI Signal -99 dbm”, while the log files I’ve seen on the web show signals stronger than -70dB?
I’ve tried:
- 2 different boards
- “2dB” and larger “5dB” 433MHz antennas plugged into the SMI connector.
- A 433MHz antenna plugged into the IPX connector, just in case the boards were supplied with that configured for use.
- Putting the boards in various locations around the house.
- Putting a ferrite ring on the USB lead close to the board.
- Powering the board over USB from a PC, and also from 2 different power banks.
Are there any other things I could try before I try building a debug version in VS Code?
