932855 - [bluedroid] Support RSSI and device type field for BluetoothDevice

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Bluetooth, defect)

Description

[Shawn Huang [:shawnjohnjr][:shuang] (as a happy gecko contributor)]

Currently bluedroid stack returns RSSI and device type (to distinguish two different types, such as BR/EDR or LE device type). Actually bluez also returns these two fields. It is nice to have RSSI value and we can use RSSI to sort device lists. So use can see the nearest device on the top of device list.

Type field defines the following device types:
* BR/EDR
* LE
* BR/EDR/LE (a.k.a Dual mode)

Receive Signal Strength Indicator (RSSI) field defines signed 8-bit value,
and is interpreted as an indication of arriving signal strength at the antenna
measured in dBm. This field had been defined in both BREDR and LE spec, which is
required to expose.

This bug will be the first step to support Bluetooth 4.0 (aka BLE).

Bug 932855 - Part 2: Support RSSI and device type field for BluetoothDevice

Hi Shawn,

Since BLE is scheduled to be implemented on Firefox OS 2.2, I'm going to cancel your review request for now. The patch should still work at that time, may need to rebase, though.

Thank you anyway :)
