I have a Mikrotik LTAP Lora gateway with sim in it that say always connected ( a few seconds ago is always on). The sim operator coverage is strong.
The problem is that end devices at the beginning sent the data but after some hours no data at all.
Why they don’t send any more data, even if gateway is always up and connected?
Any idea how to do some troubleshooting?
