EDGE820/520+ will crash when using BLE settings on phone.

Question

Hi, 
 I build a datafield for EDGE device. And it has the function of BLE setting. 
 It works on EDGE830/530/1030/1030+, but when setting value on edge820/520+, datafield will crash, which will show an "IQ" picture. 
 I have no idea what happened. Has anyone ever encountered the same problem. 
 
 Thanks for any help.

With a data field, if it's visible, the screen gets updated every second, so you can just comment out the WatchUi.requestUpdate(). What happens with WatchUi.requestUpdate() can vary by device/FW level,

Yes, you're right. I also realize that I don't need to call this function to refresh the picture in advance. Maybe it just doesn't throw an error when it is called on machines such as edge1030.
Thank you again for your help. Your responses to other questions have also greatly helped my development process.
