OTAA LoPy Nanogateway to TTN - Unable to Join



  • Hi,

    Is there a working example for interaction with the Things Network using AS923?

    I have 2 LoPys with each acting as an OTAA node and a nano gateway node respectively.
    I modified the following files as follows,

    config_py:

    SERVER = 'router.as.thethings.network'
    LORA_FREQUENCY = 923200000
    LORA_DR = "SF10BW125"

    nanogateway_py:

    RX_PK = {"rxpk": [{"time": "", "tmst": 0,
    "chan": 2, "rfch": 0,
    "freq": 923.2, "stat": 1,
    "modu": "LORA", "datr": "SF10BW125",
    "codr": "4/5", "rssi": 0,
    "lsnr": 0, "size": 0,
    "data": ""}]}

    OTAA/main.py:

    for channel in range(0, 72):
    lora.remove_channel(channel)

    for i in range(0, 16):
    lora.add_channel(i, frequency=923200000, dr_min=0, dr_max=4) #not sure why cannot set DR5

    The JOIN_REQUEST & JOIN_ACCEPT messages have been successfully generated. However, my OTAA node is unable to join the network.

    Please advise, thank you.
