RAK 7240 does not allow to select the region US915

d4n1 · July 14, 2022, 3:55pm

I am trying to configure the gateway for the 915 MHz region, but only EU863-870, IN865-867, RU864-870 appear in the dropdown.
I have updated to the latest firmware version 1.3.3, but I cannot configure it

It would be very helpful if someone knows how to solve it.

Welcome back @d4n1

There are three hardware versions for the RAK7240

High frequency version for US915, KR920, AU915 and AS923
Medium frequency version for EU868, IN865 and RU864
Low frequency version for CN470 and EU433

As the hardware is different, a gateway for the EU868, IN865 and RU864 regions cannot be used for US915, …

You need to select the frequency when you buy the gateway:

Ok I understand, thank you very much for the answer, I thought it was a firmware bug, because on the gateway label it did not put any specification of the frequency, but I understand

I have another question, can I change only the LoRa concentrator, RAK2247, RAK2287 with the right frequency, and would it detect the high frequency?, could there be a problem with this?

Hi @d4n1 no, you can not change the concentrator. The concentrator band is hardcoded in the gateway in the manufacturing process. If you bought a gateway with the wrong band, please reach us at [email protected] to check if we can help you.
