Hi Micael,
Really great help, thank you very much.
I’ll take care during opening the housing as you mentioned.
You are right, I intend to use an external micro, but I think the serial connection allows
to separate the external HW quite well.
Regarding BT, If possible I plan just to power off the BT unit and by-pass power to the
sensor by a small switch. So I do not expect unknown commands or answers. But this
is a guess.
Thanks a lot again.
Regards
Rob
