Basic station - Multitech AEP conduit

Hi,

I am trying to connect multi tech conduit to chirpstack gatway bridge. The following is the bridge configuration

[backend.basic_station]


 # Region.
 # Please refer to the LoRaWAN Regional Parameters specification
 # for the complete list of common region names.
  region="US915"

  # Minimal frequency (Hz).
  frequency_min=902000000

  # Maximum frequency (Hz).
  frequency_max=928000000

  # Concentrator configuration.
  # This section contains the configuration for the SX1301 concentrator chips.
  # Example:

  [[backend.basic_station.concentrators]]

    # Multi-SF channel configuration.
    [backend.basic_station.concentrators.multi_sf]

     #Frequencies (Hz).
  frequencies=[
    903900000,
    904100000,
    904300000,
    904500000,
    904700000,
    904900000,
    905100000,
    905300000,
  ]


  # LoRa STD channel.
  #[backend.basic_station.concentrators.lora_std]

  # Frequency (Hz).
  #frequency=868300000
  #frequency=904600000

  # Bandwidth (Hz).
  #bandwidth=250000
  #bandwidth=500000

  # Spreading factor.
  #spreading_factor=8

  # FSK channel.
  #[backend.basic_station.concentrators.fsk]

  # Frequency (Hz).
  #frequency=868800000

I am unable to recceive any uplinks from the end device…Below is the basic station log from the multitech device.

After [TX filter] [Spectral Scan] am supposed to data rate log as per this Running Basic Station on Conduit . Can someone tell me What other configuration needs to be set?
