you can see here:
hi am trying to implement both the client and server modbus application in RTU mode, any one can guide or share the sample c program for the modbus implementation.
E.g, when client request the value from the particular reg, the server need to send the user defined value present in the reg.
does this help?
You can include the libmodbus in ./meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.inc
IMAGE_INSTALL_append = " libmodbus"
