Matteo Posted June 5, 2020 Hi everybody! I recently got a lego city passenger train (60197) for my son but we have a problem when connecting hub and controller. Basically it's almost impossible! Light blinks white (should means hub and controller are searching for each other) but they fail every time. Batteries are fresh new for both. I tried resetting both so many times but it does not change. If I connect hub and/or controller with the Android app they both connect very easily! In this case both have blue light and I can control train only with app and not with remote! What could be the problem?? Thank you! Matteo Share this post Link to post Share on other sites
GianCann Posted June 5, 2020 Hi @Matteo, have you tried to update the firmware of the hub, with the PU App? Share this post Link to post Share on other sites
Matteo Posted June 5, 2020 Yes, first time I connected the hub it updated firmware. Share this post Link to post Share on other sites
GianCann Posted June 5, 2020 Do you have only one hub? In this case, try to force a new firmware update: push the power butto until the led light become purple. Then, start the App e try ti connect to him. When the LED change color, release the button. Make this operation without any motors connected. Share this post Link to post Share on other sites
Matteo Posted June 5, 2020 Just tried your solution, updated firmware with no problems, reconnected motor, tried to connect but still nothing! Controller is fw upgradable too? Share this post Link to post Share on other sites

GianCann Posted June 5, 2020 it's a very strange behavior... @Matteo you are italian like me. Tomorrow contact me via PM, to try with other test. Share this post Link to post Share on other sites
dr_spock Posted June 5, 2020 You can also test to see if the remote will connect to the PU App on your smartdevice. It should show up with the name "Handset" in the PU App Connect screen. That can rule out the remote's bluetooth radio not working. Share this post Link to post Share on other sites
mindstormsboi Posted June 6, 2020 It could be a device compatibility issue, just like I'm having with the 17101 hub (which Lego devs later proved true via email). You can contact them at lego.com/service and explain your problem, and they'll provide a replacement remote. For free Share this post Link to post Share on other sites

The remote is connecting to the app, recognized as "handset...", so it's radio should be OK. Share this post Link to post Share on other sites
Mr Hobbles Posted June 6, 2020 I’ve had similar troubles before. One thing that’s worked for me is to press the button on both at the same time while they’re both already blinking. I do this repeatedly, once a second, until they connect. Share this post Link to post Share on other sites
JaBaCaDaBra Posted June 6, 2020 (edited) Did you, at any point, try to connect the hub over bluetooth to your phone or computer? If so open BT on that device and click forget of the connection. Edited June 6, 2020 by JaBaCaDaBra Share this post Link to post Share on other sites

Powered Up uses BLE instead of Bluetooth classic, what you describe is a typical Bluetooth classic procedure. @Matteo When another peripheral is connected to your remote it won't be seen by your Powered Up HUB so really make sure there are no other devices (I don't think that is the problem, but you can check). After 10 posts at Eurobricks you can use the PM. Share this post Link to post Share on other sites

That's not what I mentioned. problem here is that people have sometimes the idea that the hub should first be connected to the phone. this just because it is the normal way how you handle BT devices. (and even the EV3 and Spike have to be connected this way first) But Boost, PU and Tech hubs however must NOT be connected this way, the app does that automatically for you. But you made this mistake the phone and hub try to connect everytime they "see" eachother and at that point neither the controller or app will work correct. So IF you ever made this mistake make sure you delete this connection from your phone so it will no longer mess up things. Share this post Link to post Share on other sites
JopieK Posted June 6, 2020 EV3 does only support Bluetooth Classic, that is why. Spike also supports Bluetooth classic as far as I know (but also BLE). What you describe is Bluetooth Classic, not BLE. Powered Up only supports BLE. Share this post Link to post Share on other sites
Matteo Posted June 6, 2020 I never connected hub or remote in any way to my phone. I only used Lego app. So I don't think this is the problem. I also tried to switch off all BT devices, including phones, in my house but boring changed! Share this post Link to post Share on other sites
JopieK Posted June 6, 2020 It is probably what @mindstormsboi says, the best to contact Service and Support of TLG. Share this post Link to post Share on other sites
Matteo Posted June 6, 2020 I contacted service yesterday, I hope they'll reply next week Share this post Link to post Share on other sites
Matteo Posted June 11, 2020 I had the possibility to perform some tests with a working set of a friend of mine. He's got two sets, cargo and passengers. My remote was able to pair with his two hubs. My hub was not able to pair with any of his two remotes. I guess problem is in the hub :) Share this post Link to post Share on other sites
