Daly 250A 4S BMS bluetooth connected but Smart BMS App shows no data

[ELEL]

Hello,

My 250A 4S Daly Smart BMS worked with bluetooth and iOS app Smart BMS fine but just somehow stopped working today.

In the screenshot below, you can see that the BMS was successfully identified by the Smart BMS app.





In the screenshot below, you can see that the Smart BMS app displayed no data.




When I pressed the "Preferences" tab in the app, the app crashed.

I tried reinstalling the Smart BMS app, restarting by iPhone, using another iPhone.... all have the same problems

The PC software is still working fine and properly displaying the BMS data without problem.

Can anyone shed me some light where the problem may be?


Thank you.

I didn't try hard enough before asking the question here.....

I reconnected the bluetooth module and it works again. Somehow the loose connection only affected the data pin but not the power pin.

Case solved.
