# BladeRF quick guide
## Intro
BladeRF is SDR device capable to transmit in range 47-6000Mhz and receive in range 70-6000Mhz.
With samplerate 0.52-61Mhz and max bandwidth 0.2-56MHz. As it capable to RX/TX on quite
wide range there is infinite possibilities what can be done with it.
## Quick test
Run
```bash
bladeRF-cli -p
```
Output will show if any BladeRF device is connected
## Running GQRX
Lunch any of command below to start graphical SDR
```bash
gqrx
gqrx-alsa //if first one fails with some pulse audio error
```
Choose device selection dialog and add to
__Device string__
```bash
bladerf=0,fpga=/usr/share/bladerf/fpga/hostedxA4.rbf
```
This will set to first bladerf and load FPGA bitstream, find path to bitstream on your PC from distro package.
Now GQRX will ready to go
### Enable biastee
If there are attached LNA or LNB to BladeRF SMA ports you can enable biastee by adding to
GQRX __Device string__ with comma separation between parameters
```bash
biastee=rx
```
## Running from command line
To start interactive commandline point to fpga bitstream, can be found in distro package.
```bash
bladeRF-cli -i -l /usr/share/bladerf/fpga/hostedxA4.rbf
```
### Receive
Set frequency to AA Megaherz with sample rate BB bandwidth CC and write to file DD in signed complex 16 bit, with 20M entries
```bash
set frequency rx AAM
set samplerate rx BBM
set bandwidth rx CCM
rx config file=DD.sc16q11 format=bin n=20M
rx start
rx wait
rx
```
### Transmit
Set frequency to AA Megaherz with sample rate BB bandwidth CC and read from file DD in signed complex 16 bit
```bash
set frequency tx AAM
set samplerate tx BBM
set bandwidth tx CCM
tx config file=DDsc16q11 format=bin
tx start
tx wait
tx
```
### Enable biastee
To enable/disable biastee set channel RX1/RX2/TX1/TX2 to 0/false to disable and 1/true to enable biastee on particular channel
```bash
set biastee RX1 true
```
## Gnuradio
Gnuradio is opensource tool that allows you to utilize DSP blocks and create
processing pipeline. It works like a block diagrams drawing tool, except the block are
DSP processing steps and as output you get processed signal. Here is example how to
create FM radio listening design and as result you can hear to your local radio stations.
## Quartus
Steps how to install Quartus and make it compile BladeRF firmware
Get the version of Quartus 20.1.1 from Intel download page. Get the whole package or
2 packates Quartus,ModelSim and CycloneV device support package. Install the Quartus.
Get the BladeRF source:
```
git clone https://github.com/Nuand/bladeRF.git
cd bladeRF
git submodule init
git submodule update
```
go to *hdl/quartus*
so now set the environment
```
export QSYS_ROOTDIR="/home/user/intelFPGA_lite/20.1.1/quartus/sopc_builder"
export QUARTUS_ROOTDIR=/home/user/intelFPGA_lite/20.1.1/quartus
export PATH=$PATH:/home/user/intelFPGA_lite/20.1.1/quartus/sopc_builder/bin
export PATH=$PATH:/home/user/intelFPGA_lite/20.1.1/quartus/bin
export PATH=$PATH:/home/user/intelFPGA_lite/20.1.1/nios2eds/bin
export PATH=$PATH:/home/user/intelFPGA_lite/20.1.1/nios2eds/sdk2/bin
export PATH=$PATH:/home/user/intelFPGA_lite/20.1.1/nios2eds/bin/gnu/H-x86_64-pc-linux-gnu/bin/
export SOPC_KIT_NIOS2=/home/user/intelFPGA_lite/20.1.1/nios2eds
```
Get the license files from Intel self licensing page
```
export LM_LICENSE_FILE=/home/user/intelFPGA_lite/LR-174976_License.dat
export MGLS_LICENSE_FILE=/home/user/intelFPGA_lite/LR-174976_License.dat
```
Now in bladerf dir go to hdl/quartus and run command to build hosted firmware
```
./build_bladerf.sh -b bladeRF-micro -r hosted -s A4
```
## Modsim
How to make modsim to run, for simulating BladeRF code
Add dependencies for modsim
```
dpkg --add-architecture i386
apt update
apt install libxft2 libxft2:i386 libxext6 libext6:i386
```
Run vsim command from where its located inside the quartus install directory
```
./vsim
```
