Colleagues, good day!
I am trying to understand the reason for the impossibility of adding this range to your devices.
Moreover, an updated version of LoRaWAN ™ 1.0.2 Regional Parameters Version: RP002-1.0.2 from October 8, 2020 appeared in Status: FINAL
And you refer to the very first version of LoRaWAN ™ 1.0.2 Regional Parameters Revision: B from Date: 2017 Feb
From this we can conclude that your device does not comply with LoRaWAN ™ 1.0.2 Regional Parameters and you are misleading the buyers of your products, referring to full compliance …
This problem can be solved simply by updating the protocol stack.
If there were source codes on GitHub, it would be possible to compile the firmware for this region ourselves, but this possibility is absent due to the lack of source codes.
