Hi Sebastian, it's a pity that your radio framework didn't go upstream. The lack of a standardized interface for radios is a problem now. Network interface for small radios, especially for LORA radios is overkill. I think Greg later admitted that because he accepted sx127x as a character driver. There was a discussion about this topic long time ago, but I don't remember where and how to find it now :) Probably the best approach is to support both a network interface for the radio and a character device. Similar to what is currently the case with CAN bus. Both approaches have their applications and use cases.
