I would use the shield that supports BLE, I would like to know if it is possible to build new packages bluetooth to transmit more data from different devices.
Do you also have a question? I'm not a fan of huge masses of text but your post doesn't include enough information to get the smallest clue of what your problem might be.
Which BLE shield are you planning to use? I have one from M. Kroll on the way. I selected it because it was easiest for me to get it to talk to the BlueGiga USB dongle. There are cheaper ones out there.
