Slooooow memory leak somewhere?

Hi,

it generaly fail to connect until I reload the screen on the Banglejs.

When you say reload, do you mean with a reasonably short press of the button (~2 seconds), or a full reboot (~10 seconds, that shows the blocky bootloader text)?

I've come across the MEMORY_BUSY error here sometimes too. In 2v15 and later it should happen a lot less often, but it does seem it can still occur. It's frustrating, but it is more of a warning and isn't a sign that memory is 'leaking'. It shouldn't affect the stability of the Bangle at all, so it's a bit odd about your issues connecting...
