What are the technical characteristics of Bluetooth?
The following are the technical characters of a Bluetooth device:
The devices are either a one chip solution or multiple chips in general. Blue tooth device has three main parts – RF, baseband processor and link manager (could be a CPU core like 8 or 16 bit Reduced Instruction Set Computer. A BT module in multiple chips, usually 2 or 3 chip, like RF on a chip are produced by certain vendors.
For a single chip solution, the following information can be used for referencing from a particular vendor.
| Package | - 81 ball BGA, 8mm x 8mm |
| Supply Voltage | - 2.7 – 3.3v |
| Power Consumption | - Data transmitting @ 4dBm – type 41mA |
| Voice Only Connection | - 15mA for HV3 packets, 30mA for HV1 |
| RI Page Scanning | - 420uA |
| Inquiry Scanning + RI Page Scanning | - 560uA |
| Park mode (1 second interval) | - 120uA |
| Standby state | - 10uA |
The components, the chip, memory and the crystal, antenna could be placed on a PCB about 20mm x 15mm. The thickness of the chip is about 1.25mm or 1.55 mm..
