I am running an RAK7268C with an LTE back haul. Typical data usage is between 1-2 MB per day. Yesterday the gateway consumed 76MB and I have no idea why. Fortunately my cellular provider paused the cellular service. This happened to me once before in August.
I am running version 1.0.1_RAK rRAK-96aa330. I have seen a couple of threads similar to this where the advice was to upgrade to the latest WisGate firmware, which I believe is WisGateOS v1.3.4. per the download site.
I have never upgraded the firmware before and want to be careful about it as I don’t want to brick the device.
If anyone has comments or suggestions about the unexpected very large data usage (and how to stop it) or how to safely upgrade the firmware, please let me know.
