If there is a better place for this question could someone point me in that direction?

Hello all, i have some problems getting everything to work properly. By the tons of searching ive done it doesnt seem to be 'this' difficult. So im extending this out you guys in hope for some feedback.

Heres the problem:
      I CAN connect the bluesmirf to arduino and successfully set the baud rate. meaning i have access to the CMD function of the module
      I CAN pair the android device with the bluesmirf
      I CANNOT send/receive data to/fro arduino.

What im using:
    i have auduino uno, bluesmirf silver, and serveral devices.
      I have tried this with several devices such as: Samsung galaxy S2, LG-G2X, Samsung Galaxy Tab 10.1 and a HTC Nexus one. The only one ive switched different roms has been the N1. so the other devices all run a custom rom. some CM other running something else. Either way, ive tried the Nexus(which ive seen used in multiple videos) with both custom and stock roms to no avail.

My set up:
     I have done exactly what the instructions ive found said to do. Ive connected the arduino to my comp( which i have also tried on osx and ubuntu and xp).
     I have hooked  the tx/rx properly along with power. ive paired the android devices. ive installed the MeetAndroid lib for arduino, and installed the plugins and app for android. Ive tried running multiple things here, but ill describe this later. But mostly, i would have expected the test plugin to function over some of the other more 'advanced' tutorials, considering it only blinks a light once it receives something.

So...
    After failing horribly at what should have been the simplest way to get up and going i began to try other things.
   
   
   ive tried just about every tutorial you can find if you google 'android arduino bluetooth' or 'bluesmirf'
   in attempt to not drag this out much further, ive tried using the rocketrobot, mobot, newsoftserial, softwareserial, follwed tips/code setting for LCD using the S2 app. seriously, almost everything the first 10 pages had to offer i tried. which there wasnt much relevant after that....
ive even tried the sl4a and python version......

I can show code if necessary but im not writting anything custom, so everything is already out there and possibly tried by most of you aswell.

One thing that caught my eye though was using the lamp demo. setting up for debugging i do infact see amarino open and succesfully connect to the socket.
So, im really hoping its something stupid im doing. I dont see the rx light switch light up and the serial monitor shows nothing.

if i can provide any further info to help possibly get me on the right track please let me know. anything, at this point, is invaluable to me and i will greatly appreciate your time.

Thank you

Correct, thats what i originally thought, but when trying to send a digital signal both high and low i dont get any results. it was odd, if i plugged two wires into arduino one for pin and other for hot or gnd and touch them respectively to the pins and to hot/gnd i would get a signal, even if the second wire was connected to another pin on the arduino. I know im not understanding this properly, which is why im researching, but so far i have failed to answer my questions. If you have any other id advice id gladly take it!
Thank you guys for the replies!

Alrighty, I posted from phone and let that big for detail, I've seen other with same size photo never seen a complaint, loads fine for me, I will keep image size in mind. On the other note, thank you, I didn't realize there was a surfAce mount board, now to figure how to solder the thing. Still not sure how to figure what   kinda signal to send it though. I'm going to get multimeter today and start poking around

My apologies if this is in the wrong section, seems general enough, hope someone can lend a hand. Ive lurked for a couple weeks now inbetween work and hobby time, ive recently got into the micro controller world and have ran into a stumbling block that i my google skills have failed to help with.
I have a couple projects in mind, but after going through the 'beginner' lessons i got to a point of trying something new. Ive coded an Android app that talks over the inter webs to a server script that serially communicates with the board that currently has lahzers representing the f/b/l/r controls. Thats all fine and dandy, my problem lies on my next step. I have a cheap R/C i purchased in hopes to control first the transmitter then ill wirelessly  build a bot as my next goal. The thing is, the transmitter is nothing like ive found in any tutorials ive came across, the hard part is.. there is no visible circuts on the back. im unsure how to send my signal from the arduino controlled board to the transmitter. The only thing ive successfully done is bridge the buttons to generate the signal.

Im already in the plans of finding a replacement R/C that will be a bit better, but for the time being im wondering if its even possible to pass a signal to this board, let alone solder anything to it to have a 'permanent' attachment to the receiver. 

Im a bit of a newb in this sense, i have done very little circuitry work, im currently in the software development field. I find this stuff facinating and would love to expand these new skills further to something more useful.
Any help is appreciated, or if needing more info please let me know!!
Thank you!
