Lora basic questions

Hi guys,
I need help with Mikrotik Lora. I’ve successivly connected it to the Internet and to thethingsnetwork.org but my device isn’t getting any communication from my local devices. For lora nodes I use SX1262 868M therefore the frequecy is correct. Do I need to configure something more? (I see some traffic on my microtik but it comes for other devices - not this mine)
Thanks for help
