Is it possible to use the MP3 shield and Bluesmirf together with an Uno? If I understand the RX and TX pins are the only ones that will work with serial so putting the bluesmirf on other pins is not possible right? Also, can anyone tell me what the combined mAh draw is for the MP3 shield, Uno and bluesmirf? Thats asuming its even possible. I read that the Uno is about 15 hours of standby time per Ah. Im trying to calculate what it would take for this comination to have a standby time of 7 days. The uno alone is about 11 amp hours if those figures are correct.
You ‘should’ be able to use the BT module on any pins using the SoftSerial library.
I haven’t tried it, I have always used the UART Rx and Tx pins. You may get a better answer posting on www.arduino.cc/forum
