Any idea if PSM should drop the PDP context and the TCP/IP session information when going sleep?
My understanding is PSM should retain all these info, so when wake up, it can seamless connect back to tcp/ip session before it sleep. however, in testing, my iot modem(Qualcomm 9205/Quectel Bg95) seems dropping the PDP, MQTT connection info before it enter sleep, so when wake up, I have to re-establish everything. that seems wrong.
Anyone with experience in this?
