Lopy low lora range

[franck]

Hello, I'm on the LoPy for a week and I can't exceed the 500 meters distance between my gateway and my node. Here is the configuration of my gateway:

lora = LoRa (mode = LoRa.LORA, frequency = 868100000, power_mode = LoRa.ALWAYS_ON, tx_power = 14, ban width = LoRa.BW_125KHZ, sf = 12, preamble = 8, coding_rate = LoRa. CODING_4_8, tx_iq = True, rx_iq = False)

and of my node :

lora = LoRa (mode = LoRa.LORA, frequency = 868100000, power_mode = LoRa.ALWAYS_ON, tx_power = 14, ban width = LoRa.BW_125KHZ, sf = 12, preamble = 8, coding_rate = LoRa. CODING_4_8, tx_iq = Flase, rx_iq = True)

What might be the causes ?

PS : I have a antenna with a gain of 3dbi on my two LoPy.

thank you

The lopy is developed and supported by pycom, you should probably post on their forum.
