Description

We are excited to add another product to our growing Adafruit
Bluefruit line, this time it's the Bluefruit EZ-Link: the best
Bluetooth Serial Link device ever made.

Like you, we have purchased all sorts of Bluetooth serial link
modules, with high expectations - we just wanted something that
worked! But nothing ever did exactly what we wanted: there was always
some configuration modes to wade through, and using one of those other
modules to reprogram an Arduino is impossible.

So we did what we always do, we went in and engineered something
better. Something that works!

The Bluefruit EZ-Link is a regular 'SPP' serial link client device,
that can pair with any computer or tablet and appear as a serial/COM
port (except iOS as iOS does not permit SPP pairing). But here is
where it gets exciting: unlike any other BT module, the EZ-Link can
automatically detect and change the serial baud rate. That means if
you open up the COM port on your computer at 9600 baud, the output is
9600, 57600? 57600. Yep even 2400. All the most common baud rates are
supported: 2400, 4800, 9600, 19200, 38400, 57600, 115200 and 230400.
You never have to configure or customize the module by hand - it all
happens completely automatically inside the RF module.

Now if we stopped there, you'd probably think "wow that is pretty
nice" but we didn't stop there! The EZ-Link has another impressive
feature: the DTR/RTS/DSR flow control pins are automatically synced to
the computer serial port. What this means is that if the computer sets
the hardware flow control DTR or RTS pins high or low the pins on the
bluetooth module will follow. If the DSR input pin is brought high or
low on the EZ-Link, the computer can detect that as well. Every other
Bluetooth SPP device we've ever seen, if they even have the RTS/DTR
pins brought out, do not sync back to the computer, instead the flow
control is for the module serial buffer itself.

Together, this creates something pretty amazing: a Bluetooth module
that can change baud rates on the fly and toggle the DTR pin as
desired. What we've got here now is a way to program an Arduino (or
compatible) from 10 meters away, completely wirelessly, with no extra
software, custom hardware, odd firmware hacks or modified firmware. In
fact, you can use the Bluefruit as a sort of 'wire free' FTDI-like
cable with any device that has an FTDI re-programming port. It works
great, and you can use the serial console as well. This package
includes the necessary 1uF capacitor between the DTR and reset pin.

To round out the design we also added two RX/TX indicator LEDs so you
can tell when data is sent & received as well as a connection status
pin. When the paired computer opens up a UART connection, the status
pin goes high, letting the microcontroller know that it can now expect
data to be sent and its also OK to send data to the computer.

Each order of this EZ-Link + Extras pack includes one ready to go and
assembled EZ-Link board, with FCC/CE/RoHS certification. We also
include a 6-pin right angle female header and a stick of 6-pin
extra-long male header. Chances are you will want to solder the female
header in to the center of the board so you can use it like an
FTDI-cable but we left you the option of wires, or other kind of
header. We also toss in a JST connector. The JST connector can be
soldered on the back (optional) to connect a Lipoly battery for
portable projects. If the JST is used, the battery can also power the
microcontroller that the EZ-Link is plugged into.
