Is there example mqtt_simple for nRF52840 which supports IPv4 and TLS 1.2

[Embedded_Engineer]

I am using SDK 16 for nRF52840 with soft device S140.

1. 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.

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?

Thank you,

Hi,

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

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?

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,
