Hi, I’m working on a project which requires monitor mode support for the onboard Raspberry Pi v3 wifi chip. It seems that this isn’t supported out of the box, but there are a set of patches which may be useful. ref: [https://github.com/seemoo-lab/nexmon](https://github.com/seemoo-lab/nexmon) Can you suggest the easiest route for me to compile the patched module for the [Balena.io](http://Balena.io) RPi image? Thanks! Alex ---

Hi Alex, Perhaps you could make use of the following repository to build a module with the patches and replace the default one at runtime : > **[balena-os/kernel-module-build](https://github.com/balena-os/kernel-module-build)** > > Example project for building an OOT kernel module in resin - balena-os/kernel-module-build Cheers… ---

Lovely - thanks @gelbal - I’ll have a go and let you know how I get on! ---

That was really useful thanks @gelbal. I’ve been working to add monitor mode to the Raspberry Piv3B and Piv3B+ WiFi drivers for a project I’m working on here. This required some underlying kernel module and firmware changes. I’ve documented the process under [Balena.io](http://Balena.io) below, and also provided some binaries for people who just want to get up and running quickly. > **[DynamicDevices/nexmon-binaries](https://github.com/dynamicdevices/nexmon-binaries)** > > Placeholder for binaries I'm building for bcm monitor mode using nexmon - DynamicDevices/nexmon-binaries ---

It’s a pleasure to assist in some small way 🙂
