基于EspBlufi蓝牙配网流程
1.初始化服务
self.espFBYBleHelper = [ESPFBYBLEHelper share];
2.扫码外设
[self.espFBYBleHelper startScan:^(ESPPeripheral * _Nonnull device) { if ([self shouldAddToSource:device]) { [self.dataSource addObject:device]; dispatch_async(dispatch_get_main_queue(), ^{ [self.peripheralView reloadData]; }); } }];
3.连接外设
3.1连接外设
_blufiClient = [[BlufiClient alloc] init]; _blufiClient.centralManagerDelete = self; _blufiClient.peripheralDelegate = self; _blufiClient.blufiDelegate = self; [_blufiClient connect:_device.uuid.UUIDString];
3.2外设连接成功失败回调
- (void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral { [self updateMessage:@"Connet device success"];}
- (void)centralManager:(CBCentralManager *)central didFailToConnectPeripheral:(CBPeripheral *)peripheral error:(NSError *)error { [self updateMessage:@"Connet device failed"]; self.connected = NO;}
3.3外设连接状态回调
- (void)blufi:(BlufiClient *)client gattPrepared:(BlufiStatusCode)status service:(CBService *)service writeChar:(CBCharacteristic *)writeChar notifyChar:(CBCharacteristic *)notifyChar { NSLog(@"Blufi gattPrepared status:%d", status); if (status == StatusSuccess) { self.connected = YES; [self updateMessage:@"BluFi connection has prepared"]; [self onBlufiPrepared]; } else { [self onDisconnected]; if (!service) { [self updateMessage:@"Discover service failed"]; } else if (!writeChar) { [self updateMessage:@"Discover write char failed"]; } else if (!notifyChar) { [self updateMessage:@"Discover notify char failed"]; } }}
4.获取外设Mac
4.1自定义发送数据来获取Mac地址
[self.blufiClient postCustomData:data];
4.2.收到自定义数据是否发送成功回调
- (void)blufi:(BlufiClient *)client didPostCustomData:(nonnull NSData *)data status:(BlufiStatusCode)status {
if (status == StatusSuccess)
{
[self updateMessage:@"Post custom data complete"];
}
else {
[self updateMessage:[NSString stringWithFormat:@"Post custom data failed: %d", status]];
}
}
4.3 收到自定义数据回调
在这里就能拿到自定义的Mac信息了
- (void)blufi:(BlufiClient *)client didReceiveCustomData:(NSData *)data status:(BlufiStatusCode)status {
NSString *customString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
[self updateMessage:[NSString stringWithFormat:@"Receive device custom data: %@", customString]];
}
5.给外设发送WiFi信息
5.1发送配网信息
// 参数封装
BlufiConfigureParams *params = [[BlufiConfigureParams alloc] init];
params.opMode = OpModeSta;
params.staSsid = self.WifiSSidTextField.text;
params.staPassword = self.WifiPasswordTextField.text;
// 发送配网信息
[_blufiClient configure:params];
5.2 配网信息发送是否成功回调
- (void)blufi:(BlufiClient *)client didPostConfigureParams:(BlufiStatusCode)status {
if (status == StatusSuccess) {
[self updateMessage:@"Post configure params complete"];
} else {
[self updateMessage:[NSString stringWithFormat:@"Post configure params failed: %d", status]];
}
}
5.3 收到配网信息数据回调
- (void)blufi:(BlufiClient *)client didReceiveDeviceStatusResponse:(BlufiStatusResponse *)response status:(BlufiStatusCode)status { [[NSOperationQueue mainQueue] addOperationWithBlock:^{ [self setButton:self.stateBtn enable:self.connected]; }]; if (status == StatusSuccess) { [self updateMessage:[NSString stringWithFormat:@"Receive device status:\n%@", response.getStatusInfo]]; } else { [self updateMessage:[NSString stringWithFormat:@"Receive device status error: %d", status]]; }}
到这里说明，设备已经配网成功了，我们拿到前获取到的Mac，进行上云操作(已云智易sn订阅为例)
6.设备上云操作
6.1调用云智易sn订阅接口
6.2 将设备添加到当前home中
6.3.修改设备名
至此，整个蓝牙配网上云流程结束
核心写入数据方法，加入了Condition锁，确保写入线程安全
- (void)gattWrite:(NSData *)data { [_writeCondition lock]; if (![self isConnected]) { [_writeCondition unlock]; return; } if (DBUG) { NSLog(@"Blufi GattWrite Length: %lu, %@", (unsigned long)data.length, data); } [_peripheral writeValue:data forCharacteristic:_writeChar type:CBCharacteristicWriteWithResponse]; [_writeCondition wait]; [_writeCondition unlock]; return;}
