Yes, the question is on the software/firmware support longevity.
Yet another question.
We have a proprietary protocol on top of LoRa (different from LoRaWan). Is it easy to use RAK833 or RAK2247 for just sending proprietary packets on top of LoRa (unicast and broadcast)?
We’ve a set of fully open source firmware for RAK2247/RAK833, which can only work on LoRaWAN now. If you want to execute your proprietary protocol, i think you can do it based on our open source firmware.
