Doesn’t matter what anyone anywhere says about anything, Single or Dual Channel Packet Forwarders are not for use on a LoRaWAN network.
Even Dragino have that on their product page. If you have an issue with any discrepancies, it’s Dragino that you need to take it up with. Or return it to your vendor.
See: Single Channel Packet Forwarders (SCPF) are obsolete and not supported
As there is no further assistance available, closing thread.
