Yes, I have seen that every first API call after reboot to a server uses some additional data compared to subsequent calls even if they are the same payload.

Thank you for the response, are you seeing increase bandwidth usage due to the re-connection?

HI,

We were unable to find the right solution, but our implementation is such that the device is a slave to the host MCU. The host MCU just reboots the modem if it sees that the network is not connected in the last 2 mins. So for us, the bandage is working.

Were you able to find any resolution to this problem? We are seeing it on other devices.

Hello,

do you have any log output from when the device disconnects, or any other useful information related to the incident?
