Problems after DFU on IOS

Hi,

We developed our device with KEIL 5, SDK15.2 and SoftDevice 6.1.1. After we upgrade the SDK on our device from version 14 to 15, our IOS phone encountered the following problem:

Use nRF connect on IOS to do DFU successfully and connected with the device again on the same IOS phone, the nRF connect couldn't search any service except the DFU service, but meanwhile, all the other phones can search all the service normally. On this situation, I only turn of the bluetooth and turn on it manually on the IOS phone, then nRF connect can search all the service.


Best regards,
Richard
