I can join TTN and communicate to TTN thru my existing gateway at home (MikroTik Lora9), but my field tester can not “see” it as a gateway on the display. Does this only find RAK gateways or any proper LoraWAN gateway? Are there certain settings I need? Im on the 915 band, channels 8-16. Scanning finds nothing either.
Welcome to the forum @MRodgers
Beside of connecting the FieldTester to TTN, did you setup the backend connection that is required for the FieldTester to work?
If not, here is the guide for TTN ==> FieldTester guide for TTN
