Hi,
I am adapting the Azure IoT example for use with the nRF5340DK and nRF7002EK.
The configuration is:
- sdk: nvs 2.6.0
- example Azure IoT hub
Initially, the getaddrinfo() function returns a failure code of -101 when called in the broker_init.
After that, I implemented the DNS resolver, dns_resolve_init(), which changed the return error to -11.
Could you please assist me in resolving this issue?
