Thanks for looking, I need help, Im stuck, and I want to finish my project without burning another board.
Happy New Years!, ive been lurking for years, finally my tinkering leads me to a concrete wall.
Actually it lead me here to the forums, THANKS!

I built an arduino uno r3 device, through the guides on the forums. A++++++

It works Great, its has a sensor, it outputs sensor readings to the serial output. A++
I know how to connect an LCD and view Output on a 16x2 LCD. A++++
It also takes that sensor output and writes the data to the SD-card shield onboard. A++

HERE WE GO

I purchased another Arduino Uno r3 and a Sparkfun RN42XVP IMAGE

I want to be able to connect my Samsung Galaxy cell phone to this Arduino with a sensor,
and view the sensor output being read on my Galaxy cell phone.

I installed SPP and connected to the Arduino with Bluetooth (rn42XVP) with success.

HELP!

I have an Arduino, with a Sensor connected that outputs to an LCD (16 x 2) and a Sparkfun RN42XVP IMAGE bluetooth adapter connected to it via a Seed Xbee Shield.

Does anyone know how I can view my Arduino Serial Output on my phone via this RN42XVP bluetooth radio?

Please do not cross-post. Threads merged.

Have you an app on your phone that can read and display the input from bluetooth?

...R

Yes, So far I used a Bluetooth SPP app to connect to the phone. I have no idea what it does and the arduino has no test sketch on it for bluetooth

Do you mean that "Bluetooth SPP" is the name of an app that runs on your phone and takes in and displays data that comes via Bluetooth? Is there any documentation for the app?

The App on my Android phone is called Bluetooth SPP Pro.

Then, I have a RN42XVP bluetooth device from sparkfun, inside of a Seeed Studios Xbee Shield on top of an Arduino Uno R3 plugged in to the usb port on my pc..

All the lights are on/flashing things look good, so far only the blink sketch is on the uno.
When I search Bluetooth with the app, it finds the device successfully!
I press Connect! Connected Successfully, The LED blinks.

Now how do I send "serial.print" data from the Uno to the android cell phone using (any app) ?

If you are asking for arduino codte you are in the right placd. If you are asking
for help using the Bluetooth Spp hen probably not.

I suggest using a bluetooth serial terminal on your phone, there are many apps just look on the google play store for "bluetooth terminal".

Then you connect app to Arduino, and if arduino sketch prints "hello world" you should read it on the terminal.

Is RN42XVP bluetooth device connected to RX and TX on Arduino?

Post your Arduino code. As your phone seems to have connected with the Arduino bluetooth device I suspect you just need to send data. But without the code who can tell.

Have you the same baudrate at both ends?

It would have been helpful if you had provided a link to Bluetooth SPP to save me having to find it.
