Wiedi Posted December 31, 2020 Hello, we got a Lego boost as a christmas present and the first days everything was fine. We build the robot and the guitar, yesterday we tried the cat and the move hub won't start anymore. When I press the green button, the white light flashes and after 5 seconds it turned in steady green. Then 5 seconds later the white light flashes and the hub goes off. I tried this with 2 compatible devices... I tried to reset the move hub by pressing the green button 10 seconds, the light blinks in violett and doesn't change the color like in the troubleshooting manual. Has anyone an idea how to solve this? Thanks Robin Share this post Link to post Share on other sites
Tcm0 Posted December 31, 2020 Did you check the batteries? Did it perform an update before that happened? Share this post Link to post Share on other sites
Wiedi Posted December 31, 2020 I changed the batteries twice and there was no update :-( Share this post Link to post Share on other sites
akira4king Posted January 3 Hi, I have a similar problem, ours did a firmware update first though. Now it will not connect to any device... I have tried 3 android phones and the Nordic Semi nRF connect app and there seems to be no BLE signal at all from the boost hub. Has anyone else had issues like this / get it resolved? Lego is currently saying over a week to answer emails... Thanks, any help would be greatly appreciated! Nathaniel Share this post Link to post Share on other sites
Tcm0 Posted January 3 You can get into firmware recovery mode by holding the green button for about 10 seconds. The LED Dwill start to flash. Then you should be able to reinstall the firmware. Share this post Link to post Share on other sites

That's my other problem... if I press the green button 10seconds, then the blinks only purple and doesn't changes the color :-( Share this post Link to post Share on other sites

When blinking, you then have to start the App to start FW-Download. Edited January 4 by Lok24 Share this post Link to post Share on other sites

I have to hold the green button to keep the light blinking, if I release the button, the Light goes off. Share this post Link to post Share on other sites

It don't connect to the handheld too... App version is 1.9.6 Where can I see the firmware version? Only if it's connected? Share this post Link to post Share on other sites
Lok24 Posted January 4 (edited) 10 minutes ago, Wiedi said: Where can I see the firmware version? Only if it's connected? no, it has noting to do with the hub. It is the FW that the App contains to be install on hubs. Under "Settings" from start screen. When you have the window of alle Hubs open and press and hold hub button till blinking purple, nothing happens? As you have more than one hub I would suggest to reinstall app. Edited January 4 by Lok24 Share this post Link to post Share on other sites
