I'm looking to create a data logger for some devices which usually connect to Android/iOS. The app that the manufacturer has produced is ok for looking at live data, but it requires the device to be kept within range (and screen on) for logging which is a little pathetic when you want to log for a couple of days.
The devices read pressure and temperature for refrigeration and air conditioning technicians.

Without knowing the specifics of the bluetooth signal (BT4.0), is there any way to receive the signal and interpret the data so it can be logged?
Why do you think Bluetooth would be any better? It still has to be within range.

The device uses bluetooth. If you don't want stand around receiving the signal, there is no way you can receive the signal and interpret the data so it can be logged. What you need is a device that will record the data on board so that you can download it at leisure via bluetooth. In short, if the device does not do that, it is clearly not intended for the purpose you propose, and the solution is to get a device that does, and therefore is.
As it stands, this is not a bluetooth problem, and is not an arduino problem either. The real problem is that you have chosen the wrong tool for the job, but your proposal sounds reasonable and I imagine there is somebody who makes what you want. You could perhaps make it an arduino problem whereby the same sensors are read by an arduino and recorded on-board to be dumped as required via bluetooth. In principle this is common enough for arduino, and you can ditch the Testo.
