NRF_SO_IPV6_DELAYED_ADDR_REFRESH

#define NRF_SO_IPV6_DELAYED_ADDR_REFRESH   62

#include <nrf_modem/include/nrf_socket.h>

Delay IPv6 address refresh during power saving mode.

By default, if the lifetime of an IPv6 address expires during power saving mode (PSM) or eDRX sleep, the device wakes up solely to refresh the address.

If this option is enabled, the IPv6 address refresh is delayed until the next time the device wakes up from PSM or eDRX sleep. This avoids unnecessary wake-ups and optimizes the power usage. The option value is an integer, a 1 value enables delayed IPv6 address refresh on IPv6.

The default value is 0 (OFF).

Note

This is only supported by the following modem firmware:

• mfw_nrf9160 v1.3.7 or later
• mfw_nrf91x1 v2.0.2 or later
• mfw_nrf9151-ntn
