Hi Billy,
The problem that your are experiencing is down to the B2 software version. It is so out of date that the 'SW Upgrade' and the 'Web Upgrade' functions will not work in your case. You have two options to fix this issue.
1. Purchase an updated SDcard from Brennan; the card arrives with the updated B2 software already installed. I think that the price is around £10.
OR
2. Reflash your existing SDcard with the latest software that can be downloaded from the Brennan website (free of charge).
Below are instructions if you want to try option 2.
I have posted this for other 'non-techy' users who have found it useful, so hopefully it will useful to you.
The SD card rebuild process is reasonably straight-forward to do, although it looks a bit scary when you look at the instructions. Below is a link to those instructions. Look in the left hand panel of the webpage and scroll down to 'New SD Card'.
There are two download links in that webpage; one for 'balenaEtcher' and the other for 'B2BNOV2019.zip' file. These are all you need to rebuild your SD card.
The 'balenaEtcher' is the software program that is required to flash the SDcard.
I have boiled the instructions down into a series of summary steps below, which might be of help to you.
You will need a 'USB - SDcard adapter' if your PC/Mac doesn't have an SD card slot fitted.
1. Download & install 'balenaEtcher' onto your PC/Mac (from the webpage in the link shown above).
2. Download 'B2BNOV2019.zip' to your PC/Mac (from the webpage in the link shown above).
3. Power down your B2.
4. Remove the SD card which is protruding out of the side of the B2.
5. Plug the SD card into PC/Mac
6. Start up 'balenaEtcher' application on PC/Mac.
7. Point 'balenaEtcher' to the B2BNOV2019.zip file. (DON'T unzip the file)
8. Click on balenaEtcher 'Start' button. Answer 'Yes' or 'OK' where appropriate to a couple of confirmation messages that will pop up.
It will take 'balenaEtcher a few minutes to flash and verify the SDcard.
9. On your B2, plug in the newly flashed SDcard.
10. Power up the B2.
11. Check the software version which should show as 'B2B Nov 06 2019' (or possibly 'B2B Mar 17 2020' - either date is fine).
12. Run a 'Web Upgrade' to further update to the latest software from the Brennan website.
13. Reboot the B2
14. Run a software version check - should now show 'B2B Oct 06 2020' (or very similar)
So from a bare SD card to full upgrade should take approximately 20 minutes to complete.
Let us know how you get on.
Regards,
Peter.
