HTTPS on TRB256

[martinek]

I would like to ask for assistance regarding HTTPS communication on the TRB256 device.

We need the unit to send HTTPS POST requests (to an Event Juggler service) from within a client’s private network. The target server uses a self-signed certificate.

Could you please confirm the following:

1. Does the TRB256 fully support HTTPS for outbound POST requests? (in “Ation type” there is only HTTP no HTTPS)

2. Is it possible for the TRB256 to accept and work with a self-signed certificate?

3. In case the device does not trust the certificate by default, is there an option to manually upload/import a custom CA or certificate into the TRB256 so that HTTPS communication can function properly?

Any guidance or relevant documentation would be greatly appreciated.

Thank you in advance.

Best regards,

[Vilius.G]

Greetings, martinek,

Thank you for your message.

I noticed that you already have an active topic regarding this issue here:

TRB256 periodic HTTP Post

Hi, I need your help configuring a Teltonika TRB256 to send periodic HTTP POST “keep-alive” messages (JSON) to a test endpoint: http://nekamtoposli.cz/keepalive Payload: { “modemId”: “Test-Revitest” } Goal: send the POST every 60 seconds. I have TRB256 FW version: TRB2M_R_00.07.11.3 Thank you in advance for a quick reply Václav Martínek

To keep the discussion consistent and avoid fragmentation, I kindly ask you to continue in your existing thread.

Best regards,
V.

Hi,

I opened a new thread because in the original one only the first part of my question had been answered, so I thought it might be clearer to start a separate topic specifically for the current issue. I also hoped it might get a bit more visibility — usually someone replies within a day (which I really appreciate!), but this time it got stuck and I’m still struggling with the problem.

But I will go back to the first issue
