Problem connecting SX1276 to TTN

Hi all, I've followed configuration guide for Multitech MultiConnect Conduit and successfully connected it to TTN. (https://www.thethingsnetwork.org/labs/story/configure-your-multitech-mlinux-conduit-for-the-things-network)

I've registered on TTN and add my GW to my profile. I can see it online.

On node-side, I've a STM32L152 together with SX1276 shield. I've created a new application on TTN Dashboard. Then, I've added a new device to the application - ABP type - and copied DevEUI, AppEUI, DevAddr, ArtSKey and NwkSKey into my program. I compiled and programmed my node. (https://developer.mbed.org/teams/Semtech/code/LoRaWAN-lmic-app/)

While looking at my Dashboard, I don't see any uplink messages. Did I forget sth? Am I misunderstanding sth?

I performed same actions on loriot's cloud and it works.

Could someone help?

Thank you

LMIC is old and no longer maintained. Please use https://developer.mbed.org/teams/Semtech/code/LoRaWAN-demo-76/ because its up-to-date. For use with conduit gateway, be sure you have end-device configured for the same frequency band and 8-channel operation. The define USE_BAND_* in board.h needs to match your gateway channel configuration.
