Bluetooth Receiver

Following are the Main Features of Bluetooth Receiver :-
1. Battery needs to be 220 mAh and rechargeable.
2. Reference size 50mm x 42mm x 10mm.
3. The configuration may be done through Serial or one time bluetooth config (One time config only, re-config can only be done at factory).
A. Functional requirement:
1. The Bluetooth module will run on a battery which shall be chargeable.
2. We have a mobile application which creates an SPP service (say BTSpp )
3. The module, when booted, should connect to the SPP service on the phone (BTSpp) and also to the "COM 1" service on phone (The phone is Nokia S-40, C1-01 phone, which has COM 1 SPP Service).
4. Whatever data is received on the BTSpp service should be sent by the module to COM 1 service and whatever response is received from COM 1 service, should be sent back to BT Spp service.
5. If the connection gets disconnected or lost, the module should automatically reconnect and establish the connection whenever it can again.
6. The module is paired to a phone. Thus, the module should have configuration option where we can set the MAC address of the phone which it should be paired with.
B. Physical/packaging expectations:
1. The module with battery and a recharging circuit, needs to be put in small plastic casing
2. The plastic casing should have 2 Lends (For BT module status and for charging indication).
3. The plastic casing should also have a switch to on/off the module.
