If you want to use the %RAI command, then you need to combine it with the socket option. You can test that, but I'm not 100% sure if this will work on rel 13.

I got RAI working using the first option, but I wonder if I can also use the setsockopt version, because this will allow me to bind the RAI to specific sockets. Using lte_lc_rai_req(true); and lte_lc_rai_req(false); around socket send() is possible, bur prone to error because you can't control when a packet is sent trough the modem. I tried adding the setsockopt but it does nothing, does this only work with rel 14/NB-IOT2 RAI?

I use

prj.conf:

CONFIG_UDP_RAI_ENABLE=y
CONFIG_LTE_RAI_REQ_VALUE="3"

and in the code

lte_lc_rai_req(true) or lte_lc_rai_req(false)

For me that works quite well.

There is also an other question about RAI with a more elaborated answer.
