Are you actively using the BMS? (Charging or drawing power) it might have gone to sleep.Hi all, this is my first post and I am a newbie. I bought two JBD SP15S008C 80A bms's from "JIABAIDA Official Store" on Ali Express and the first one that I installed work fine out of the box. But then all of a sudden it stop communicating data to the mobile app. The bluetooth connection appears to be ok because I am able to select it on the phone but then no data shows whatsoever. Now I've been patiently trying to establish communication with the seller but their customer service is just non existent. I have tried their XiaoXang app,(various versions), the Overkill app but no success. I ordered the usb module to try the PC software but is on its way. I see a blue light lit on the Bms and on the bluetooth dongle so I am kind of hoping that they are still recoverable. Well this is so long for been my first post, I just hope someone can help me out here. Thanks
Thanks for your reply, I think I have tried all of your suggestions already, disconnecting both the Bluetooth module and the balance wiring more than one actually but still no success. About your last remark on the apps, can you provide more info on the subject. Thanks again.Are you actively using the BMS? (Charging or drawing power) it might have gone to sleep.
Try just rebooting your phone first.
Try disconnecting the Bluetooth module and reconnect it (i mean physically unplug it)
Then try unplug the balance leads from the BMS and plug them back in.
If you have multiple apps loaded that can communicate with the BMS, the default app sometimes can't see the info.
if you have the overkill app on your phone and connect with that, the JBD app won't be able to see the BMS, because the BMS is still talking to the overkill app... you have to close the overkill app properly, make sure the blue LED on the bluetooth dongle goes out, then connect with the JBD app for it to work.Thanks for your reply, I think I have tried all of your suggestions already, disconnecting both the Bluetooth module and the balance wiring more than one actually but still no success.

Is there a way to get the blue light to go out if it's stuck always on? Even after unplugging it and plugging it back in, the led is on full time and I think this is why my app won't see the bms.if you have the overkill app on your phone and connect with that, the JBD app won't be able to see the BMS, because the BMS is still talking to the overkill app... you have to close the overkill app properly, make sure the blue LED on the bluetooth dongle goes out, then connect with the JBD app for it to work.
May be worth contacting your supplier, it could be a fault with your BMS or Bluetooth module?Is there a way to get the blue light to go out if it's stuck always on? Even after unplugging it and plugging it back in, the led is on full time and I think this is why my app won't see the bms.
