Maybe a stuped question, but I tried to search it in this forum and on the internet, but couldn’t find it anywhere.
In the examples of matthijskooijman (ttn-abp and ttn-otaa) and Ed Smallenburg (ESP_LoRa_tracker) different methods are used to setup a frequency plan.
- ttn-abp: in setup a whole frequency plan with 9 channels.
- ttn-otaa: no frequency settings at all.
- ESP_LoRa_tracker: in setup only one channel (at 868.1MHz).
Who can tell me (or where can I find it) who and where makes the choise where the transmit frequencies are determined? Is it the TTN-server, the gateway or LMiC? Or the application itself?
Thanks and regards…
