I did, TMRpcm works perfect but TMRpcm and bluetooth (Hardware Serial) don't work together. With Simple SD Audio, bluetooth works perfect but i don't get any sound. Actually, i don't get any sound with standard internet codes too.
My Arduino and Speaker connected or wired well. (I know, because TMRpcm works perfect by itself)
My Micro SD Card Product has a voltage regulator. (5V to 3.3V)
So, I'm trying a little bit more. Thank you.
