    I have tried with different configurations in AEP but I only receive 11 bytes in LoRa, can I receive more bytes or is it the limit?, the region configuration is US915, and how many devices can be connected to the gateway IP67 with LoRa.

    Hi Fernando

    US915 supports Spreading Factors SF7 through SF10.
    The Spreading Factor is configured in the LoRa endpoint.
    SF10 has a limitation of 11 Bytes payload, but provides longest range.
    SF7, SF8, SF9 all provide larger payload. See Spreading Factor and Bandwidth
    table at the link below.
