Bluetooth Module Recommendation

I’m looking for recommendations on a standalone serial to bluetooth module. Here’s the scenario I will be using:

One bluetooth module (Master) receiving GPS correction data from an Ipad, Windows, or Android device simultaneously broadcasting to 2 bluetooth modules (Slaves) connected to 2 GPS receivers via RS232 serial. In summary, the modules would need the following capabilities:

  1. Compatible with Apple Ipad, Windows, and Android devices.
  2. Point to Multi-point capability.
  3. Powered via 12 Volt DC

Recommendations will be greatly appreciated. Thanks!

take a look at this part 2087-TNP-NSR103-ND has the operating for the 3 systems, however lower voltage.
