Very nice demo !

I'm trying to down-grade 1.43.7 (which doesn't work for me, an i2c problem I suspect), to 1.43.5. I take the 1.43.5 4x .bin files from the zip and replace the files in the build folder of a copy of 'annex_package_full_1.43' with the 21/4/21 Toolkit. When I flash the chip I still get 1.43.7. What am I doing wrong? Its a wroom-32. Even erasing the flash doesn't clear it.

Also, the flasher offers three firmware versions 1.43.2 and two 1.43.5 versions. But there doesn't seem to be a way to select which to use. It would be very helpful when experimenting to be able to select available versions from a list.

Hi Stuart

without having had a look at the Annex-toolkit at the moment: wasn't there a "config"-page in the toolkit, where you can select the firmware file to use?

You are right, thank you. I hadn't realised that I could change things here. I am confused about file names as the version isn't in the name, which makes mistakes easy. I shall start again from scratch.

I'm trying to work up to the latest version that works for me in the hope that some odd errors go away (such as 'endif without if' when the code is good and has already looped thousands of times). v6 blocks the console with messages, and v7 seems to have an i2c problem.

I did not see the endif-problem until now, but I'll keep that in mind now. Tnx!
Can confirm the rest

Well I'm pleased to say just for the record that after 60 hours running on 1.43.3 (from 1.43) the unwarranted 'endif without if' errors have not reoccurred.
