Hello, I found a strainge problem, I have a indoor bike Nexgim, which can be connect using bluetooth (NOT ANT+).
When using PC, Nexgim can be connect by zwift as controllable through bluetooth.
However, when using android, zwift cannot connect Nexgim as controllable.
Any suggestions?
Hello @space_cool welcome to Zwift forums.
You may have to give the Zwift app permission to access the Bluetooth hardware on your Android device.
When you ran the Zwift app for the first time, the app should have asked you for permissions to access the Locations folder. In Android, Bluetooth permissions are buried under the Location permission (itās not obvious, but thatās the reason).
If you denied permission to the Location folder, you can allow permissions for the Zwift app. How-to has been discussed here. If youāre running the newest version of Android, itās buried under two levels of folders.
Alternately - you can uninstall the Zwift app, then reinstall, and give permissions the next time.
Hello, @shooj.
Iāve already given the permissions to both zwift and companion app. Please refer to attached picture.
However, on android, the bike can only be connected as normal device, controllable cannot find this bike.
On pc no problem.
both platform, Iām using bluetooth, not ant+.
Best Regards
Thank you for checking that setting, and also attaching screenshots.
Controllable trainers should connect without issue over Bluetooth, so this is puzzling why it does not. One possibility is that it might be specific to that Android device. Would you have a different Android device to test?
Yes, very strange, Iām using huawei P20 PRO, and no second android device to test.
@space_cool
Thank you for listing the phone model. Huawei P20 Pro is being used successfully by members in this thread. Letās assume for a moment that the phone is not the issue.
Is this the Nexgim exercise bike you have? It is not on Zwiftās list of supported trainers. The specs say āBluetooth 5.0,ā but this does not mean that the bike is designed to work with Zwift in mind. There are exercise equipment companies that make Bluetooth-capable products that only work with their own proprietary fitness apps.
Wish I had better news for you, but we canāt say that this bike will work.
Yes, itās this nexgim, the most strange thing is when Iām using PC version zwift, can successfully connect to this bike in controllable mode.
tried uninstall and reinstall, also not work. @shooj. PC still works. 
may I ask anyone knows why this happensļ¼
any way to get it work on Android deviceļ¼
-thanks
all i can suggest is that you try and connect it as controllable before pairing it for power and cadence, the others will auto connect after that
really thanks.
this time it works, not sure whether itās due to todays update
Hey,
I just got this bike and Iām having problems connecting it as āControllableā on all platforms.
Is yours working consistently on all platforms? Windows and Android?
Thanks in advance!
which bike did you get?
I encountered the same problem, reboot ipad and solved it 
The release firmware does not support Controllable, you need to contact customer service to upgrade the firmware
