    When downloading the images, choose the required image file for download. How to set up LSE01 to work in 8 channel mode By default, the frequency bands US915, AU915, CN470 work in 72 frequencies. Many gateways are 8 channel gateways, and in this case, the OTAA join time and uplink schedule is long and unpredictable while the end node is hopping in 72 frequencies.

  • Page 29: Device Rejoin In At The Second Uplink Packet

    Cause for this issue: The fuse on LSE01 is not large enough, some of the soil probe require large current up to 5v 800mA, in a short pulse. When this happen, it cause the device reboot so user see rejoin.
