J16

Hello, I would like to know about J16 if the platform is compatible, as it is not uploading.
I am using the following command:

SERVER,0,myip,5023,0#

thanks

I'm having the same problem, and I've tried the solutions you've proposed. When I pass a port other than 5023, the device sends the information to the server, but gives an error, which is to be expected. But when I pass port 5023, the server log doesn't register anything, I've already tested the port and it's working, it seems to be something in the device. Do you know what it could be?

Logs?

the last logs are these, I have two applications: one that simulates my tracker (it is connecting correctly) and the tracker, when I send port 5001 or another shows the log, when I change to 5023, no logs arrive on the server.

I don't see anything from your device. I think you made some false assumptions.
