How to convert miso/mosi on Arduino robot( atmega32u4) to rx/tx : the object is to control arduino robot ( by using a bluetooth serial connection ? Any person can help me ?
Add a SPI UART to your project.
Or a Bluetooth module with SPI interface. I see a lot of chips, have to hunt around and see if someone makes a module from one of these
Like this one

or search for another that uses the same TI chip.
Connecting bluetooth module to miso/mosi pin on robot control board (normally miso/mosi used for the screen) , choosing pin 14/16 as serial connection and compiled the code as leonardo ( it has the same processor ) the serial conection works and i can send data to -->robot arduino control but
If i compile the same code as 'robot control board' error appears the cause is softwareserial libray it seems i have to make some changes in this library (there is rx/tx connection between the robot control board and 2nd board 'motor board'
