H/W Flow control for xE910 modules

  1. Hi,

     

    Can I clarify something – are the only lines needed for h/w flow control on the UART for the xE910 modules CTS and RTS?

     

    Should DTR/DSR be connected? (Our existing drivers don’t support these lines anyway)

     

    Kind Regards,

    1. RTS/CTS lines are enough for hardware flow control however DTR and DSR can be used for other useful things, make a review of them simply looking in the AT Commands Reference Guide doc.

      1. Thank you Cosmin – that is very helpful. Will look to connect these to GPIO pins.
