Hi. I have set up an Arduino UNO + Dragino LoRa shield as a simple LoRa node. I have a RAK7249 16-channel gateway configured for AU915. This is the code that I am using is from the ex ttn-otaa in GitHub - mcci-catena/arduino-lmic: LoraWAN-MAC-in-C library, adapted to run under the Arduino environment.
The issue I have is this piece of code which I added
// The frequency plan Au915 is hard-coded in lmic_project_config.h
// The band (or selected 8 channels) is configured here!
for (int channel = 8; channel < 72; ++channel)
{
LMIC_disableChannel(channel);
}
It disables channels 8-72 so I would expect packets to arrive on my gateway in 0-7 channels. However, the "Duty Cycle of the LoRa Channel" graph shows it operating across all 16 channels.
I only have the one node running, yet it is sending packets on channels 0-15. What do I need to do to discipline packets to channels 0-7 please.
