篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ios BLE读取蓝牙地址相关的知识,希望对你有一定的参考价值。
主要思路:
1,连接BLE
2,读取1803服务下面特征值2A23的数据
//扫描到services
- (void)peripheral:(CBPeripheral *)peripheral didDiscoverServices:(nullable NSError *)error
if(error)
NSLog(@"didDiscoverServices error");
return;
for (CBService *service in peripheral.services)
//扫描每个service的characteristics
[peripheral discoverCharacteristics:nil forService:service];
- (void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(CBService *)service error:(nullable
...
for (CBCharacteristic *characteristic in service.characteristics)
if([characteristic.UUID.UUIDString isEqualToString:@"2A23"])
if (characteristic.properties & CBCharacteristicPropertyRead)
NSLog(@"start read....");
[peripheral readValueForCharacteristic:characteristic];
else
NSLog(@"2A23不支持read");
...
- (void)peripheral:(CBPeripheral *)peripheral didUpdateValueForCharacteristic:(CBCharacteristic *)characteristic error:(nullable NSError *)error
NSData *data = characteristic.value;
NSString *resultStr = [self hexStringFromNSdata:data];
if([characteristic.UUID isEqual:[CBUUID UUIDWithString:@"2A23"]])
const Byte *bytes = [data bytes];
NSMutableString *str = [[NSMutableString alloc]
initWithFormat:@"%02X:%02X:%02X:%02X:%02X:%02X",
bytes[7],bytes[6],bytes[5],
bytes[2],bytes[1],bytes[0]
];
NSLog(@"macString===>%@",str);
....
