Flashing Photon without internet

[Moors7]

You're confusing two things. The Particle Dev (offline IDE), works by compiling the code in the cloud, after which it gets the compiled .bin back. For that, you indeed need internet access. Should you wish to compile locally, you'll have to set up a local toolchain, Luckily, @mumblepins was kind enough to create a windows installer:

Toolchain for Windows Installer

So, in an effort to make local building easier for people, I put together a basic installer for the Toolchain for Windows. It should download and install GCC Arm, GNU make, and the necessary components of the MinGW toolkit, and add them appropriately to the path. I generally followed @kennethlimcp’s guide here. I tested it on Win 7, so if something doesn’t work, let me know and I’ll try to fix it! This should decrease the number of steps necessary to get up and running with building locally…

If you want to flash them wirelessly without internet, you can set up a local cloud:

This will guide you through on how to Setup the Local and use it with Particle-CLI after a successful installation. Before you proceed, make sure you fired up particle-server successfully at least once. We will need the server public keys generated on 1st run later. **NOTE: ** This will point the Particle-CLI to the local and you will not be able to use features available on the cloud 1.) We will now create a new server profile on Particle-CLI using the command: part…
