Hi every one,
I have a Grove-Wio-E5 and nucleo-f446xx dev board.
Because the lack of instrution, I don’t know what to do to transmit data between 2 nucleo using Grove-Wio-E5.
Do I have to configurate or programming anything in Grove-Wio-E5, or just simple connect Tx, Rx to uart of Nucleo and use it?
If there is any document about how to use, please help me!
Hi there,
And welcome Here.
I would just use the AT commands from the nucleo to E5 and same on other end. Don’t over complicate stuff. Make a point to point connection, then send data either both ways or one way at a time.
Full or Half duplex. You have sensors or something on one of the nucleo’s?
If so create a data packet with that info (hex, ASCII)and send it over read and display on the other end.
