thank you for your answer.
So, here is my response (I hope translate.google.com does a good enough job!)
The objective:
- Single chip cellular phone
- This single chip only needs to do one thing: make telephone calls with SIM card
- The only method of user interface with the chip would be through bluetooth (ergo chip must have bluetooth)
- So, the finished product would do the following:
- Take a SIM card inside it
- Connect to a Bluetooth handset
- Take commands (make calls, accept calls, reject calls and SMS but no internet connection) from the Bluetooth device
