你好,
我们将在两个巨大的混凝土房间中部署16个新设备。房间约500米长,每节四节。 此外,房间是弯曲的,这使得它更困难。在段之间有一个厚的混凝土墙和一个相对较小的开口。 我们需要知道蓝牙类的新的物联网开发工具包,以获得它可以桥接的距离吗? 此外,可以通过中继器扩展信号,如果是,哪个中继器是合适的? 设备本身能充当中继器吗?如果是的话,这个特性需要在软件中定制吗? 另一个问题是:ADC组件限制在12bit SAR还是在PSoC 5LP上存在的20位ADC也可用? 谢谢你的帮助。 最好的问候 斯特凡 以上来自于百度翻译 以下为原文 Hello, we will deploy 16 of these new devices in two huge concrete rooms. The rooms are about 500m long and segmented in four segments each. Moreover, the rooms are curved which makes it more difficult. Between the segments there is a thick concrete wall and a relatively small opening. We need to know the bluetooth class of the new IoT development kits to derive the distance it can bridge ? Also, can the signal be extended via repeater, and if so, which repeater would be suitable ? Can the device itself act as a repeater, and if so - would this feature need to be custom developed in software ? A further question: is the ADC component limited to 12bit SAR or is the 20bit ADC which is present on the PSoC 5LP also available ? Thank you for any helpful insight. Best Regards Stefan |

似乎没有人,塞普拉斯包括,感觉像看这个…
我终于找到了信息:062-BLE套件的特点是一个BLE 4.2,有一个10米的范围。 猜猜是蓝牙类2? 以上来自于百度翻译 以下为原文 Seems like no-one, Cypress included, feels like looking into this... I have found information finally: the 062-BLE Kit features a BLE 4.2 and has a range of 10m. Guess that is Bluetooth Class 2 ? |

zbinxiang 发表于 2018-12-17 15:20 功率类是蓝牙经典属性,AFAIK并没有真正用于低能量的设备中,因为1)在相同的功率水平下,该范围高于经典,2)LE设备通常会调整发射功率以匹配接收端。 在LE中需要知道的是最大发射功率和接收机灵敏度。 以上来自于百度翻译 以下为原文 Power classes are a Bluetooth Classic property and AFAIK aren’t really used in Low Energy only devices because 1) the range is higher than Classic at the same power level and 2) LE devices will typically adjust transmit power to match the receiving end What you need to know in LE really is the maximum transmit power AND receiver sensitivity |

wb197 发表于 2018-12-17 15:26 有没有人知道最大发射功率和从BLE 4.2的062-BLE实现的最大范围是多少?或者如何扩展这个范围? 谢谢你的帮助 以上来自于百度翻译 以下为原文 Does anyone know what the maximum transmit power and from that the maximum range of the 062-BLE implementation of BLE 4.2 is ? Or how to extend that range ? Thanks for any help on this |
