I need a Bluetooth 4.0 data logger of 5 channels of temperature that can transmit this information to my phone (android/Iphone), i would like to configure from my phone the scan time from 1 second to 1 minute in increments of 1 sec.

The temperature sensor should be thermocouple or any other sensor that can read in the range from 15C to 45C with an accuracy of 0.2C

A need that this device storage let say 10 readings and the send to the phone(also configurable te qty of readings), or respond to a command from the phone to pull the information. in case the phone is not near, the device should store all the readings and as soon as it pair with the phone it will send all the information and continue measure.

I need this device to storage up to 1 day of information in the internal memory

I need it that works with 1 coin battery so it should be very efficient im looking for 1 month of battery life.

Next phase of this project should be to improve the device to be able to be rechargeable or have at least 3 months of battery life.

I need the prototype and the app
