Coexistance of nrfutil for standard ble dfu and mesh dfu

[Shubham]

Hi,

I am using https://github.com/NordicSemiconductor/pc-nrfutil code from here for nrfutil. I am working on both mesh and standard ble application.h
I am facing problem keeping both nrfutil at the same time. I have used master brach for standard nrfutil package and mesh_dfu branch for mesh nrfutil package.

Is there a way where both could co exist nrfutil and nrfutil for mesh?


I did a small hack for this.
Installed nrfutil with pip3, this will install nrfutil packages to python3 dist-package path. Renamed `nrfutil` bin file to `nrfutil_non_mesh`, so that following step wont overwrite it.
Built and installed mesh_dfu branch using pythn2.7 this got installed at python2.7 dist-package path. Renamed `nrfutil` bin file to `nrfutlil_mesh`.
Renamed back `nrfutil_non_mesh` to `nrfutil`

Hi. 

There should be no issue with having both versions installed at the same time.

 Don't see any problem doing it like this, as long as it works for you. 

Best regards,

Hi,

I worked but is there any other way? Because, python2.7 will be absolete by the end of this year. So we may have to migrate to python3.  Is there a way to install it at custom path, dropping nrfutil for mesh binary at different path?

Hi.

 As stated in the documentation, nrfutil (mesh) is a legacy serial tool written for py2. 

This might get an update in future releases. 

Documentation: 

Important note about Python
Python is not required to build the mesh stack and examples. The nRF5 SDK for Mesh uses both Python 3.5 and Python 2.7.

Tasks that require Python 3:

• working with Interactive PyACI script Mesh tool
• generating SEGGER Embedded Studio projects
• building documentation

Tasks that require Python 2:

• starting DFU transfer with nrfutil. This is a legacy serial tool written for py2.

Thanks Joakim,

I found an alternative for it. I used virtualenv, one for mesh_dfu branch and one for master.

Built the package for each one and added the alias for the binaries in bashrc, one for nrfutil(master branch) and nrfutil_mesh(mesh_dfu branch).

Even this is working fine.
