Hi,
I'm having some problems with the IoT library and the power driver. When the program call the "ipv6_medium_init" function, it asserts internally. This happens when this function calls the "nrf_drv_power.c" driver, in line 357, when checking the flag "m_initialized".
I posted some time ago a question about this issue but no response so far. Here is the link of the post for more details and source code:
