I have connected Quectel’s EC25-E with the development board and enabled Quectel’s connection manager. The setup has done successfully. But when i do throughput test, it fails by showing the below error message ,after establishing connection:
iperf3: error - control socket has closed unexpectedly
Is there any other settings to do to overcome the issue?
Are you using public server? Or do you use the CMW500?
Seems the network is not stable. If you are using the public network with normal sim card, you might see such errors.
Yes, I am using public server. But I am able to test with udp protocol. But why would be the TCP protocol fails. When i do iperf3 test in tcp mode the following error happens:
iperf3: error - unable to read from stream socket: Resource temporarily unavailable
It need to collect the log of the modem and log from the carrier side.
If UDP is working, it means there is no problem with the route path.
