Hi
One question. Do you receive packets from radio 0? Because I have one TTGO and one Heltec ESP32 and the gateway only receives in radio 1, it seems the channels in radio 0 are not listening:

Since here the log doesn’t show any activity until the modules start to send in frequencies associated to radio 1.
I’m using it by usb, but I think there is not difference if I connect it by SPI with a Raspberry Pi Zero W.
What can I do?
interesting
