Too bad, faulty Bluetooth pairing

The device itself: very easy to use and complete, to calculate lengths, areas and volumes ... and therefore very useful to know the quantities of materials to purchase.
And as he adds, it is possible to measure beyond the reach of 50 meters, provided we give it an "obstacle" to which the laser pointer, and then we reparte this point. Ideal to know the area of ​​a field, except in broad daylight the red dot is not visible. By late afternoon, overcast, it works.

However, I am disappointed by Bluetooth which I expected a lot of the work planned for this summer. Two free applications are available. Unable to establish connection with that for the general public. So I downloaded the professional version, also more attractive because that can save several projects, take photos, annotate them ... then go to the DIY store, phone or tablet in hand, to have all data under the eyes. Alas, I was able to connect two or three times, and during the short period when both devices were paired, I could not (or understood how) to transfer the measurements from the rangefinder to the tablet. Then break free ... and impossible to come back for several days.

The rangefinder itself deserves 5 stars but Bluetooth connectivity, capricious, not even enough time to understand how to use the application. It lacks a tutorial to solve the problem, I seek, I have not found.
