I have two mqtt-in nodes pulling data from thethingsnetwork:
These two nodes pulling from the same server (but two different applications).
One of these nodes always gives me a ECONNRESET error.
Can you give me a hint how I can research that issue any further?
It’s a demo traccar server (demo3.traccar.org) and for my TWO GPS-sensors dragino LGT92 I need TWO application. Or am I wrong?
This is what I have done for each of the two sensors:
New mqtt-broker
→ server config: choose name
server: „eu1.cloud.thethings.network“, Port 8883; activate SSL/TLS.
new TLS-configuration → new name
server-name: eu1.cloud.thethings.network“
download root-certificate (ISRG Root X1) from Let’s Encrypt in new config „CAcertificat“: https://letsencrypt.org/certs/isrgrootx1.pem
tls-config->security: username: TTN-application-ID@ttn“, e.g. „my_application@ttn“.
password is the API-key, for which you have to generate a API-key in TTN web-GUI „Add API key“ (Grant all rights)
Topic: „v3/application-ID@ttn/devices/Device-ID/up“; e.g.: „v3/my_application@ttn/devices/my_end_device/up“
You find the end-device-name in TTN web-GUI.
Are the decoder different for the different firmware version?
If not you can still use the same application in TTN as long as when you create the tracker on the application you specify the correct version for the firmware.
