this is a screenshot of iperf test, between device and mobile phone. The distance between them is less than a meter. As you can see, the connection is periodically broken. If a PC is connected to the device, then there are no any disconnections.
If the device is in access point mode, as soon as I connect the smartphone and run the iperf test, periodic disconnections immediately appear.
if the device is in client mode, the smartphone is an access point, then there are no disconnects.

i designed 4G LTE ip camera which send data to server over UDP. Camera havent static IP and server too. I want to use p2p or vpn for communication tunnel between camera and server.
