Errors when using 4G router #39

Open krambriw opened 2 years ago

krambriw commented 2 years ago

Running this on a RPi3, bullseye, works fine but what is causing those error message every time?

Any hint to fix this?

Suddenly it can go into a mode with just errors, then sending one or more messages successfully, then errors again

The Node.js example does not show this type of problem
