Telit FAQs, Part 12: Do I need hardware flow control or can I just use RX and TX without the flow control signals?

Wednesday, March 11, 2015

The purpose of hardware flow control is to make sure that you don’t lose any data. We always recommend using HW flow control if you are sending or receiving data. If you are just sending AT commands to the module you are fine without hardware flow control.
