Certification is an interesting point. First of all it is available only for 868MHz end devices, but nor for gateways, network servers, etc. Also even if you have a certified product you can reconfigure without hacking to be out of compliance. In the Microchip stack you can do nearly the same config changes as in RN2483 but you can not fully blow it up.
@Mike-K Did you select the correct country in the firmware flasher when flashing your lopy? This will determine if you get the 868 or 915 firmware version and thus which frequencies you can use. From the docs:
"frequency accepts values between 863000000 and 870000000 in the 868 band, or between 902000000 and 928000000 in the 915 band."
