The demo provided at Github for CC2538 doesn't describe the test procedure. If one follows the procedure described for POSIX (for an older version), then start command is not valid.
Though the documentation help lists start as a command, but it is not a valid command (in cli.cpp).
Can someone guide me through the test procedure?
I found it, its mentioned in apps path, which was missed by me.
