Hi,

[quote user=""]I am interested in using mqtt over lwip on IPV4. Available example is for IPV6. though headers of IPv4 exist (\external\lwip\src\include\lwip) but no example utilizing it can be found. I hope someone could point to the right direction.[/quote]

No, there is unfortunately no support for ipv4. IPSP, the service used for getting ipv6 connectivity with BLE, doesn't support ipv4.

[quote user=""]2. I came across a post where using mbed TLS might not work along with Softdevice (central/Peripheral role) in IoT SDK. Is this true?[/quote]

Mbed isn't mentioned. What is being asked is if you can run 6lowpan (IPSP) as a central, where the nRF acts as the router. That is still not supported.

Kind regards,

Håkon
