Hi Moshe,

Could you please take a modem trace and share with me so I can see what is going on at your side.

Hi Martin,

Thanks for your answer,

I am not sure this is the issue I am having as I am able to send messages of ~4kb.

also if I understand correctly, my code snippet above is suppose to overcome the 2KB TLS output buffer.

Hi Moshe,

The TLS output buffer has a size of 2kB, and there is a bug that you do not get a notification that the messages are too big. (this will be fixed)

So the solution is to have shorter messages.

Best Regards,
Martin L.

Hi Martin,

Yes , it does work otherwise.

Hi Moshe,

So the application works otherwise? e.g. you are able to publish smaller packages?

I think it should work with 8K since it should split in MTU-size chunks, normally 1500 bytes chunks.

Are you on LTE-M network or NB-IoT network?
