I have a cornfield full of Arduinos. Currently I have to visit each one open up the control box that they are in and re-program them individually. I would like to replace them all with Photons and program them wireless. I have the ability to set up a wireless network but not internet ability. Is there a way to flash a Photon with the local IDE over a wireless LAN?

Answered my own question it’s not yet available without internet access.

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:

> 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](https://community.particle.io/t/toolchain-windows/11635). 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:

> [@Tutorial: Local Cloud 1st Time instructions \[01 Oct 15\]](https://community.particle.io/t/tutorial-local-cloud-1st-time-instructions-20-march-15/5589):
>
> This will guide you through on how to Setup the Local cloud 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 cloud and you will not be able to use features available on the spark cloud 1.) We will now create a new server profile on Particle-CLI using the command: part…

Thank you.
