RAK811 Spreading Factor

ton12 · November 11, 2019, 6:34pm

Hi all,

I am trying to use RAK811 Wisnode to send data to a gateway. I would like to ask if there is an AT command to manually set the spreading factor and bandwidth for my transmission under LORAWAN mode?

Thank you.

You can view these commands in the documentation to modify your SF.

Hi @ton12,

You can use the following AT command to set the DR/SF for RAK811 which run with V3.x firmware.

There is no AT command for bandwidth yet.

Hi @Fomi and @Nicholas,

Noted. Thank you for your replies. I would like to know what is the default bandwidth used by the RAK811 for transmission? And other than AT commands, is there a way to change the bandwidth for now?

This is the bandwidth specified by the protocol.
