I tried to switch to OAT. Now I use new API
"api.nrfcloud.com/.../long-range/devices/bulk" with OAT bearer token for devices creation
instead of old API: "">api.nrfcloud.com/.../devices" .
I send POST with body format:
id + ",,,APP|MODEM,\"" + certificate + "\""
like before. But I get 400 Bad Request. What can be a problem?
