I’m fighting some sort of event loss with a bunch of LoRaWAN sensors. At this stage it’s not quite clear whether it’s the physical events that we’re missing, or radio/network issues. I’m persisting the data with the Data Storage Integration that’s part of TTN. Is there a way to store the LoRaWAN frame counter (FCnt up/down) in there as well? Or do I have to use the CLI or a library to collect that information for a while?
