Rak 7243C change ism band

Hi everyone,

I am working on Rak 7243c. I am using AU915 frequency as I am living in New Zealand. Suppose if I move to Europe is it possible to change frequency to EU433. Can i change the configuration and make it work?

Hi @james_kakes,

For software, RAK7243C has a unified software image including all frequencies which are defined in the specificate of LoRaWAN 1.0.2, and users can change the frequecy freely on the configuration UI.

But for the hardware, RAK7243C has 4 kinds of hardware: 433MHz, 470MHz, 868MHz, and 915/923MHz. So you can’t use your AU915 RAK7243C as an EU433 RAK7243C because it can’t work on EU433, although you can change the frequency in software.
