}
}

Thanks, but the result is

Key:kcbadvdataisconnectable, Value:1

Key:kcbadvdatalocalname, Value:simplebleperipheral

Key:kcbadvdataserviceuuids

UUID (0): FF F0

Key:kcbadvdatatxpowerlevel, value:0

I want to get the broadcast data or not read ....

For iOS devices, I get broadcast data through Kcbadvdataserviceuuids.

Li Zongwu:

I also feel that the broadcast data should be in the advertisementdata, can be inside is no kcbadvdataserviceuuids this key value. Tangled.... I don't know if it's CC2540, it's not the right program.

-(void) Centralmanagerdidupdatestate: (cbcentralmanager *) Central

{....} How does this define the AH ...

Using the code I provided earlier, I can get kcbadvdataserviceuuids This key value, which corresponds to the so-called data in the broadcast.
