UDP questions

Hello,

I work on nbiot evaluation and i try to send udp data from my basement.. I boot and attach network from ground-floor and when i'm on PSM mode im going on basement.

I wonder when i wake up from to PSM mode to send my udp data if my nbiot module need a reception phase (RX) from eNb to send data ? My test doesn't work and i wonder why i don't receive data on my server... It's possible my nrf9160 need reception phase from the eNb even if i deactivated message from RAI config?

I use control plane cIoT EPS optimisation.. maybe it's possible to send data without reception from eNb when i wake up from PSM ?
