option 2

Use this option if you are planning to connect several electronics to your Naze32 that will use serial data like a OSD, Bluetooth etc. We will output the telemetry data through a softserial port. This is a "virtual UART", so not a real UART (altough this doesnt matter!). You MUST use PPM for this to work since we need the RC input pins!
Connect your FrSky receiver (like the d4r-II) to your naze. Connect the External analog telemetry Rx port of your FrSky receiver to RC input pin 6 on the bottom of the Naze32 (See figure 2 in the manual)
Go to the CLI tab and type the follow codes:
enable the softserial port since we will be using softserial port instead of the real UART port
feature SOFTSERIAL
[$[Get Code]]
Enable Telemetry
feature TELEMETRY
[$[Get Code]]
Set the baudrate of the softserial to 9600 to communicate correclty with the FrSky receiver
set softserial_baudrate=9600
[$[Get Code]]
Set the softserial port 1 to inverted, since that is the way the FrSky protocol works.
set softserial_1_inverted=1
[$[Get Code]]
set the port on which you would like to put the telemetry data out (we use "1", since that is telemetry output over the soft serial rc input pin 6)
set telemetry_port=1
[$[Get Code]]
set the protocol for the telemetry output (we use "0" to select the FrSky protocol)
set telemetry_provider=0
[$[Get Code]]
Save everything, it should be working now!

Calibration - RSSI
If using analogue RSSI on the OSD select "Enable ADC 5v ref"
If "Enable ADC 5v ref" is changed, save and restart the OSD
Via OSD menu

With TX approx 2-3 m from the RX, select calibrate RSSI from OSD menu
When timer reaches 10, turn the tx off and wait until the timer finishes counting down before turning back on
Save settings
Minor adjustments can be made on the GUI if necessary
Via GUI

Set RSSI min to zero and RSSI max to 255 and write
With TX off, increase RSSI min and write. Repeat until OSD reads 0% consistently
With TX on, decrease RSSI max and write. Repeat until OSD reads 100% consistently
