Hi all
I am using stm32 and LoRaMaC for end node in region US915.
I can successfully receive downlink messages when the end node is configured to used low datarate (DR1, DR2), but I cannot receive any user-defined downlink message when using DR3, DR4. I still sometimes able to receive MAC messages (with f_port 0), though. Maybe, TTN has some limitations for this?
Device is located close to the gateway
