Electron TCPClient.write issue

Nice, and true :slight_smile: and you problem is still strange. As I explained, I have an issue with .print() not with .write().

In this case what about UDP? UDP is a packed protocol. But as for sure you know, data might be lost. But maybe this is something that you can live with?

Another thing, since you send data over 3G, what if the cellular provider is messing with the data that you send? :open_mouth: You should defiantly test some code over WiFi. And then copy and paste it on the Electron, if that code create bad result, then you should talk straight to some Particle people.
