I don't have a nicknames ,

Could not connect to devices

Similar to what someone said above, I had the two devices side by side with Bluetooth on and just could not get the devices to pair. Not sure if it was the laser? Is there a process to it that I missed? Seemed as if you got one button and open the app you should be good, but it did not work.

Developer Response ,

thanks for sharing your feedback with us. Here are the steps to connect:
1. Open the app.
2. Turn on Bluetooth on both your levelling tool and your iPhone.
Now the app should connect automatically with your tool. If the Bluetooth LED on your tool is flashing you should be able to connect. A blue, non-blinking LED indicates that the tool is already connected to a smartphone.
If you still face problems, please contact app.support@bosch.com. Thanks!

Great laser, however, the app has bugs that need fixing, when trying to increase the beam intensity to high it will cause the laser to lose the Bluetooth connectivity

Developer Response ,

Hello and thank you for your review.
Because this is a bug we cannot replicate, you could help us a lot with sending a detailed description to our app support (app.support@bosch.com).
Thank you in advance!
