Hi! if you need some help I have 3 packs seplos boxes with bluetooth and I can make tests. I saw that on display board with bluetooth there is also space for an esp12f board. If you want to test this I can add a board there, I can also give you access to my systems if you want to test directly yourself. Have a good day!

Hy Syssi,

have been trying to get the bluetooth to work for the last few days, but unfortunately can't get anything out ...

any idea what I can do to make it pull the data?
Here is the debug log from the current attempt:

@manznOnly thanks for poking around. This feature isn't ready yet but your logs look promising already. Just the requests aren't implemented yet so we are sending garbage at the moment:

@syssi Here are the bluetooth specs for 10E. You could put them into the doc section.
