I’m using LTE connectivity through Hologram with a SIM7000A modem, and even when I’m able to connect, send and receive TCP data over the network, I 'm still not convinced about the robustness of the communication. Of course, I’m not comparing it to ethernet or even WiFi, but I see communication errors very often, making very difficult to deploy this into a production environment…
I usually get TCP connection timeouts, or SEND FAIL messages, or timeout in send operations. I’m using very high values for timeout in every operation, but so far, there are always some errors in a middle of something making the overall experience very poor… Packet sizes are ~ 400 bytes.
Signal quality is 21 (+CSQ). Not sure if this is a problem with my modem, or environment, etc.
Is there someone really using this cellular data in a real environment (out of a testing environment)? Are you also getting communication errors very often? If so, how do you deal with this?
Thanks in advance.
