easy Erico , the micromite in the bull provides a serial port, on this port i bind a wifi modul wifi
with serial i/o . on the start the modul open an a hoc wlan network.
join in the provided network with a tab or a handy.
send some strings with the network commands in glbasic to the micromite.
micromite test the strings and do something if the strings correct.
whats all.
the really fun with booth is the use of basic. Glbasic for the Tablet/phone and Mmbasic for the bull.
@ Mentalthink yea i can use also an arduino but the owner from the bull isnt a programmer and
if he will change something in the code he need help.
with basic and a good structured code he need not much help only some tipps.
its an old bull and sometimes "he has his own head"
