I have the power, ground, and tx,rx lines soldered onto and ready, I don't have a working TX/RX microcontroller solution at the moment, however I was wondering if I could connect the rx to the tx lines, so if I connect using BlueTerm https://market.android.com/details?id=es.pymasde.blueterm and try to type something to the bluetooth, I want it to just echo it back (as a test).
Would something like this work/make sense? Or will there be voltage/other issues? (I don't have a PC with bluetooth or serial support, so really my phone is the only option atm)
Thank you, Tyson
