In my case, I need BG95 to connect the the same MQTT server every 10-15min to upload data.
my original plan is to establish an MQTT connection -> upload data -> go PSM for 10-15min to save power -> wake up from PSM to upload data again.
I was expecting the follow up server communication after the first connection should be fairly quick, like 2-3seconds to just send one msg to MQTT. However, I realise after enter PSM, the MQTT session is being killed on the device side, so I have re-establish MQTT again, which takes 10-20 sends easily. How can I avoid this reconnection of MQTT ? any expert advise?
Isn’t PSM suppose to allow me to get back to the previous TCP/IP session without start from beginning again ?
