Haven't used account in around a year - devices no longer send data

I’m using a TTIG gateway, with custom boards. They all used to work fine, sending/receiving data through the gateway. However, now nothing seems to go through the gateway to TTN. The gateway shows connected in my account, solid green LED. However, no data is ever uploaded. Firmware hasn’t changed on the devices sending to the gateway.

Using the LMIC library, shows EV_TXSTART, then EV_JOIN_TXCOMPLETE: no JoinAccept. Nothing shows up in the live data for any device tested.

Has something changed on TTN in the past year? If not I’ll get a new gateway, and try it out.

What do the GW console logs show if you look at live traffic? (Whilst power cycling the devices)

Is it seeing the Join Request?

Is there then a Join Accept to send back?

If you just stopped using the devices the LNS may still be retaining old session info. Reset session for devices in the console then trigger a re-join, you never know :wink:

If you decommissioned the devices were antenna removed? Have they been put back correctly? Did you power up without ant in place? (Dont - may cause damage!)
