pc-ble-driver-py cmake error

[Nathan_49]

Hi,

I'm using a nrf52 as pheripheral BLE in embedded system with sensors. I need a ble central to receive the data from the sensors by connecting to the nrf52. I'm trying to use pc-ble-driver-py for my raspberry 3 by following this GITHUB but without success. I've got an error when i'm trying the cmake command in the /pc-ble-driver-py/build/

I've a Raspberry 3 and raspian stretch lite 4.14.62-v7+ (i've made a fresh install). I have list all the command i typed.

INSTALL BOOST

- sudo apt-get install git make gcc g++

- sudo wget dl.bintray.com/.../boost_1_67_0.tar.gz
- tar xzvf boost_1_67_0.tar.gz
- export BOOST_ROOT=/home/pi/boost/boost_1_67_0
- cd $BOOST_ROOT
- ./bootstrap.sh
- ./b2 toolset=gcc cxxflags=-fPIC cflags=-fPIC address-model=32 link=static --with-thread --with-system --with-regex --with-date_time --with-chrono

BUILD pc-ble-driver-py

- sudo apt-get install cmake swig libudev-dev python python-dev
- git clone github.com/.../pc-ble-driver-py
- git submodule init
- git submodule update
- cd build
- cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DARCH=x86_32 -DBOOST_LIBRARYDIR=/home/pi/boost/boost_1_67_0 ..

.. And there it is where i get error.

 

My guess is that boost library is not linked or something like that but i can't think of a solution. I need help to make it work...

Thank

Hi,

 

-DARCH=x86_32

Remove this line when configuring/compiling libboost, as you're on an ARM arch.

Remember to remove the build/* files before regenerating using cmake.

 

Best regards,

Hi,

Thank, the building work. Now it's done, can you give me a hint about how to make my central? My nrf52 use Nordic Uart Service to transmit the sensors data.

EDIT : I'm looking in the python folder and try to run example. The readme say to run "python setup.py install", but i get an error :"ImportError : No module named setuptools". It's the very first line of setup.py. Where can i find setuptools ?

Regards,

Nathan

To install setuptools, you can run any of these:

"python -m pip install setuptools", or "apt install python-setuptools"

 

There's examples on how to run the wrapper here:

Kind regards,

Hi,

Thanks for the help, it help me install the pc-ble-driver-py. Now i'm running heart_rate_collector.py to scan ble device and i should see my nrf52 but it didn't.

I programed my nRF52 with arduino IDE following this github. I'm running the exemple serial.ino and i can connect and see the "tick-tack" with the app nRF Toolbox on my smartphone.

How can i do like my smartphone with my raspberry?

Hi Nathan,

 

We do not have any examples for linux + bluez, but there are community alternatives which should run on RPi, like noble (maintainer is the same guy as you linked to): https://github.com/noble/noble

Here's an example made with the "nordic uart service" (ble_nus) with the above library: https://github.com/tigoe/BluetoothLE-Examples/tree/master/noble/readSerial

Note that noble runs on a generic bluetooth dongle (like the one in RPi3), and not with pc-ble-driver.

Kind regards,

Håkon
