    Enable WiFi and Bluetooth on Pi Zero 2 W


The following steps worked for me, but consider them untested. Use at your own risk!

That being said, the process should be fairly quick, as long as you use the custom image provided in this thread. Otherwise, the Pi02 won't even boot.
Setup

SD card


Download the image from the linked thread, and write it to your SD card

https://community.victronenergy.com/comments/122282/view.html


Create a directory in your SD card named, firmware/brcm

This is where you'll put the relevant files for the script
The name is arbitrary, so you can change it. Just make sure to update SRC_DIR, in the script


Firmware


Download BCM43430B0.hcd, from this repo, and move it to your SD card's firmware dir

Here's a quick link to the raw file


From this other repo, download all files matching, brcmfmac43436-sdio.* (should be three), and move them to the SD card's firmware/

Scripts


Copy the patch script to your SD card, so that we can access it when the system boots (it doesn't need to go in firmware/)
Edit /u-boot/config.txt by adding ,krnbt=on to the miniuart-bt overlay. You only need to do this for [pi02]; it should look like the following This is now handled by the newer images

Install


Boot the device with your SD card
Run the resize script, which also makes the rootfs writable:

/opt/victronenergy/swupdate-scripts/resize2fs.sh

Set the datetime on the machine to the current UTC time using the following pattern, YYYY-MM-DD HH:MM:SS. Why? My instances were stuck at the time of epoch, and my bluetooth didn't work properly until I did this. Maybe others don't have this issue? Use the following command to set the datetime:

busybox date set YYYY-MM-DD HH:MM:SS
Bluetooth


Run the patch script added from the Install step:

. /u-boot/venus-os-pi02-patch.sh

Run dmesg | grep brcm to see if the patch was applied properly. If no errors, reboot your device

After reboot, WiFi and bluetooth should be working (maybe even before). Run hciconfig -a, to confirm hci0 is "UP" and running.
WiFi


Once BT is setup, you should be able to find the Pi02 in the Victron Connect app, and a lot of the setup will be just like any other Raspberry Pi

Connect and Pair with your device, and setup the WiFi connection, from the app


Or, you can setup WiFi from the CLI using connmanctl

More details can be found here:

connect-via-wifi

Configure

Setup Root User

Continue to setup your user:

set_access_level_to_superuser
