BLE113 Bluetooth 4.0 module with CR2025 3v battery power supply
Your main concern with any wireless module on a low-performance power supply is to design in very heavy decoupling. Coin cells in particular - excluding recheargable lithium ion type (which are very rare) - have internal resistance up to about 100 ohms, so you will not be able to draw more than a couple of milliamps from them. As your BLE113 module is specified to draw up to 18mA, this will significantly reduce your battery lifetime or even pull the battery flat . The solution for this is (obviously) to use a big energy reserve in the form of an aluminum electrolytic capacitor of enough capacity to deliver all the energy needed for a single transmission.

Then obviously also make sure your average power consumption does not exceed what the battery can deliver (efficiently): power down the wireless radio as much as you can as well as your microcontroller or whatever other active devices you have in your application.
