[Ovmsdev] Simple TCP client

[Mark Webb-Johnson]

What are you trying to do?

From a design point of view, it seems strange to have an outgoing tcp connection from a vehicle module. Those modules need to be very responsive and realtime.

Mongoose is the correct approach. But take care, because most of the work is done in the network (not vehicle) task, so you need to deal with mutex and other concurrency issues.

Regards, Mark
