hi this is Phillip and today I’m going
to give you some tips and tricks about
how to use the H Co 5 Bluetooth low energy module maker module
with Arduino I’ve been given a pair of H
Co 5 Bluetooth modules a bit of time ago
and I really like people using them and
I would like to give you guys three tips
are ways to use it the first one is
basically the code that I already
uploaded to my github so I’m gonna have
the link in the comments and what that
code do does is that every time you
start your Arduino it’s going to force
set the mode for either the slave or the
master and the way it does that it has
to power down and then power up and set
the the mode and then force another
power down and power up to really reset
the mode so that takes a bit of time but
it works every single time so the cool
thing about that mode is that if you
have to switch the Bluetooth modules
around and you don’t want to have to go
and say this is the master and all that
you can say to the code basically do it
every single time force the reset and
I’ll wait the time that it takes so
that’s one way to use it another way is
to use it basically once you have set
the mode the cool thing is that those
little guys they they remember the last
mode so all you need to do once you have
that done once is to in it and then link
through the master so what you do is you
power up the slave and then for the
master you just follow up and then you
call the init command and then the link
come in and it’s going to link to the
slave and it goes much much faster so
basically it’s the exact same code as
the first thing that I just described
except you remove or uncomment the part
that sets the mode so you save a bunch
of time so that’s very interesting the
last one that I really like is that you
can bind the two together so you can
tell the master that it’s basically we
call the bind command and you
give the MAC address of the slave and
from that point on the cool thing is
that as soon as you power them up you
don’t have to do anything so as soon as
they’re powered up the master is looking
for the slave and it connects it
decrease the connection right away so
basically you just power them up so
there’s nothing but the power right now
and they’re connected as soon as they
have power and if I disconnect one or
the other as soon as the power is back
they will want to make that connection
again is actually it’s the new master
that triggers it but the connection is
made every single time it’s a little bit
like you Mouse you know you don’t have
to reinstall your mouse every time you
you plug it into your computer so this
this is a very very cool little feature
so I hope you enjoyed this and go get
the code and if I get the more cool
stuff out more you make more videos and
blog about it bye guys
