Thanks guys. I'm a little worried TBH because the first thing the app did when I started it up for the first time was to update the firmware. I'll try new batteries and see if there's any difference. The brickcontroller app looks interesting. If much rather use a gamepad over a phone.

Hi everyone (who clicked on this topic), I got the 42099 set this Christmas. It's my first technic. It was great fun to build and drive. I am experiencing the app disconnecting intermittently. Surprisingly googling didn't fetch any answers for this issue. Low battery perhaps? I hope it's not a faulty set. And another question while I'm at it. Now that I've built the truck, I'd like to try my hand at building my own off road crawler. What would be a good set to add interesting and useful parts?
