I have a Bosch GLM165-27CG tape measure which is listed as compatible with MagicPlan. However, it gives a lot of trouble connecting via Bluetooth. When it does connect, sometimes it drops off, and does not reconnect.

I also have a GLM400 and a similar thing, however, with the 400, I just have to connect every time. If it auto turns off, I just have to reconnect whereas, the 165 does not connect at all.
