MQTT native TLS

[basvkesteren]

Hi,

Using nRF Connect SDK 2.7.0 on an nRF9160. Using native tls, works fine, i can setup HTTPS connections.

Problems arise when i try to use MQTT with native TLS (with set_native_tls = true in struct mqtt_sec_config). This breaks with "net_sock: get_sock_vtable: (main): Invalid access on sock 4 by thread 0x20021608 (main)".

Using MQTT without native tls (thus not setting set_native_tls = true in struct mqtt_sec_config) does work, if i modify the server side encryption in an appropriate manner. Iow, it would appear that the problem is not in the application code?

Is this a known limitation? Or am i doing something wrong?

Thanks in advance,

Hello,

This is not a known limitation. If you show me the code and configs and can try to check if you are doing something wrong. Also, modem trace would be very helpful.

Hello Hakon,

Good to have it confirmed that this is supposed to work. Problem is on my side then :)

I'll see about making a small project with just the mqtt part; this is part of a bigger project, and right now i'm wondering whether some of that other code is causing this..

Thanks thusfar,
