Re: [Bluetooth mesh]unprovisioned device (micro:bit) can't be discovered

Hi Kai,

Hijacking the thread a bit here but have you considered using an nRF52-based board instead of the micro:bit? There's quite a few of them in really interesting form factors, including the reel_board and many others:

(unfortunately I cannot filter by nRF52 but you can look around)

Hi Johan,
Thanks for the prompt reply.
I think you're expert of Zephyr Bluetooth, I have two questions before getting into the detail for optimization:
1. compiling same sample code, like sample/bluetooth/mesh/, compared with v1.12.0, do you think v1.14.0 is hungry or efficient for RAM consumption?
2. as your estimation, how many bytes will be consumed if add persistent storage?

Best Regards,

I wouldn’t say it’s impossible. I bet there’s still place for memory optimisation, e.g. thread stacks that can be shrunk, buffer sizes & counts that can be lowered, and possibly unneeded features that can be disabled. Someone would just need to find the time to look into this :)
