The documents are quite confusing.
This is what I have done.
- run ic880a-gateway/install.sh, but it says some files or links already exist.
- create my own thing network account, add my gateway, add application, and a 811 device.
- In /opt/ttn-gateway/bin , I modify global_conf.json to AS1 band and link local_conf.json to my own remote-configure. Start gateway by ./start.sh
- Lora gate can connect to the thing network successfully.
- Configure 811:
at+set_config=dev_addr:... nwks_key... apps_key
at+set_config=ch_list: from 0 to 7 corresponding to AS1.
at+set_config=ch_list:8 ~ 71 as off
- Send data by at+send=1,2,11223344556677889900FF, but I got at+recv=6,0,0. Sometimes I notice that CRC error on Pi's terminal. Sometimes I see no RF packets received by concentrator.
