Android Pairing Bonding

Since PandwaRF Android Release 1.4.0 we have added a new security mechanism to protect your PandwaRF from un-authorized access. The new un-authorized access protection feature uses the BLE bonding process.

You now have to choose whether you want to use this new security feature or not.

• If you enable un-authorized access protection, a smartphone can only connect to your PandwaRF after pressing SW2 button on PandwaRF board.
• If you disable un-authorized access protection, any smartphone can connect to your PandwaRF, without any button pressed.

Button	Short press	Long press (>2s)
SW1		Shutdown PandwaRF
SW2		Enter Whitelist bypass mode
SW3		Delete all bonding information
SW4
SW5	Reset

If Whitelist is empty:

• Whitelist mode is inactive
• Every phone can connect to the PandwaRF without pressing SW2.
• Once connected, a phone must bond with PandwaRF to be allowed to reconnect later without the need to enter Whitelist Bypass Mode again.
• If phone is connected but doesn't bond with PandwaRF and then disconnect, phone will able to reconnect later using Whitelist Bypass Mode and assuming PandwaRF Whitelist is still empty.
• As soon as a phone is connected and bonded, the Whitelist is no more empty. New phones can only be connected if SW2 has been pressed before.

If Whitelist is not empty:

• Whitelist mode is active
• Only the phones in the whitelist can connect to the PandwaRF without entering Whitelist Bypass Mode.
• Phones not in the whitelist will have their connection attempts rejected.

• However, after the device disconnects, the whitelist will take effect again.
• To permanently disable whitelist advertising, bonding list needs to be cleared by holding SW3 for more than 2s
