Issues with mkrwan 1310

I just bought 2 boards. I have a lorix one GW (EU) working OK with others nodes based in LMIC and ESP32.

The mkr's send about 80-90 packets and stops. The (no) solution is reset the board.

Is impossible receive a downlink. I check the two boards with firmware update.

Somebody have better experience with 1310?

Can you upload your sketch?

Are you sleeping? If you are, downlinks are tricky because you can miss a downlink if you are asleep when it arrives.

I am sending more than 1440 packets a day.
