Question

Hello.

I try setup 2 pcs of TRB142 like a "long RS232 cable" using LTE network. Both have SIM cart with privat APN and IP address.

1st TRB has IP1, configured as Server lisening on port 5000. 2nd TRB has IP2, as client, connecting to IP1. In Realtime data -> connections, I can see established connection between IP1 and IP2 on port 5000. Using raw mode.

I make a double check RS232 parameters on both TRB has the same, also on RS232 devices on the ends. But serial data cannot flow thru.

Pls can you see some wrong config? Using TRB1_R_00.07.03.4

Thanks.

Ivan

Hello,

Could you update to 7.04 simply to rule out firmware issues?

I would also like to review your configuration. 

Please attach troubleshoot files from the devices by editing the question. Make sure to  replicate the issue, then access router's WebUI, go to System -> Administration -> Troubleshoot section and download troubleshoot file from there. The logs in the file might provide more insight into the issue.

Attached files are private and visible only to Teltonika Moderators.

Best regards,
