2. General Requirements
2.1 Features
The board must provide the following features:
• Give dual mode BT connectivity (Classic & Low Energy), so BT4.1
• Integrate the antenna, done with copper tracks on the PCB
• Interface to the motherboard with UART and PCM, USB not required.
• Permit a very low cost solution.
• Give ease of re-use for other products (simple process, no RF expertise).
2.2 Standards
2.2.1 BT related certification
On the Bluetooth.org website, the existing certifications of BT solutions are listed.
The certification strategy will be as follows:
• Make a certification for the board, with embedded low part of the BT stack, and antenna
• Make a product certification, where the BTDB is in the Phone. Here we can take benefit
of the module certification
• Following the first product certification (ex: NOE3GEE), the next products which use the
BTDB will need minimum or no certification, on condition that the used upper BT stack (in
host processor) is the same as the one of NOE3GEE.
It is necessary to make a BT qualification for the BTDB with its antenna.
This will qualify:
• The hardware, radio parts
• The Lower part of the BT stack (below HCI interface) located in the BT chip
• The Upper part of the BT stack, which runs on the Host processor.
This is why, if we re-use this board, a big part of the certification does not need to be done.
See chapter 4.5.1 for discussion about the “module” aspect for BT certification.
