LSN50 LoRa Sensor Node User Manual 54 / 60
For example, in US915 band, the frequency table is as below. By default, the end node will
use all channels (0~71) for OTAA Join process. After the OTAA Join, the end node will use
these all channels (0~71) to send uplink packets.

When you use the TTN network, the US915 frequency bands use are:
● 903.9 - SF7BW125 to SF10BW125
● 904.1 - SF7BW125 to SF10BW125
● 904.3 - SF7BW125 to SF10BW125
● 904.5 - SF7BW125 to SF10BW125
● 904.7 - SF7BW125 to SF10BW125
● 904.9 - SF7BW125 to SF10BW125
● 905.1 - SF7BW125 to SF10BW125
● 905.3 - SF7BW125 to SF10BW125
● 904.6 - SF8BW500
Because the end node is now hopping in 72 frequency, it makes it difficult for the devices to
Join the TTN network and uplink data. To solve this issue, you can access the device via the
AT commands and run:
AT+CHE=2
ATZ
to set the end node to work in 8 channel mode. The device will work in Channel 8-15 & 64-
71 for OTAA, and channel 8-15 for Uplink.
The AU915 band is similar. Below are the AU915 Uplink Channels.
