hw flow control ? #50

Closed dannybackx closed 2 months ago

Seeing the board schematic (not just RXD/TXD connected between esp and sim7080 but also DTR and RI) I would guess hardware flow control is possible. However, I can't seem to find the right settings and they're not (I think) in any of the examples.

How should we set them ?

Hello @dannybackx

I don't think DTR and RI are meant for hardware flow. See section 3.3.2 RI and DTR Behavior in SIM7080G Hardware Design document.

Thanks Felix

Thanks for clarifying.
