sample firmware for nRF52840 that operates in a 3-wire system with only Rx and Tx for UART communication

jojojo

Is there a sample firmware for nRF52840 that operates in a 3-wire system with only Rx and Tx for UART communication and no hardware flow control?

    Hi,

    Can you elaborate on what you mean by a 3 wire system? Is it VDD, GND and data? If so, is it just one way (Rx or Tx), or both ways? If the latter you would have to connect both pins together and do one direction at a time. This is sometimes done and will work. There is no example of that in the SDK, but there are some old threads about id in this forum, for instance here.

    You can find examples for UART communication for both the nRF Connect SDK and nRF5 SDK.

    If this is not what you need and you need more specific guidance, then please elaborate on what you want do to.
