未获得完整的BLE外设名称 [英] Not getting full BLE peripheral Name

问题描述

我正在通过BLE从BLE设备获取数据

I am getting Data from BLE Device by Delegate

• (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)外围adsData:(NSDictionary *)advertisingData RSSI:(NSNumber *)RSSI

但是我没有从这种方法获得完整的peripheral.name.我的BLE设备名称是-d7bce65 3fa1b4bf但我得到-d7bce65(名称由sapce截断)

But i am not getting full peripheral.name form this method. My BLE Device name is - d7bce65 3fa1b4bf But I am getting - d7bce65 (name is truncated by sapce)

请帮助.

推荐答案

广告数据限制为31个字节.除了本地名称，您的设备可能还会发送其他信息，例如服务UUID.如果所有信息都无法容纳31字节的有效负载，则本地名称将被截断.

Advertising data is limited to 31 bytes. Besides the local name, your device is probably sending other information like service UUIDs. When all the info doesn’t fit in the 31 byte payload, the local name gets truncated.
