This is my process:
1.connect a device;
2.search characteristic and set notify to yes;
3.make sure characteristic.isNotifying = YES;
5.connect again,the same device;
6.the characteristic's property isNotifying = YES(I do not discoverCharacteristic and setNotify.)
i think the value of isNotifying is wrong,
Could you helpe me how can i get the right value?
I think that the CBCharacteristic object is no longer valid after the disconnection.
Check what is value after step 4. I believe that the value would still be isNotifying == YES.
