DSGW-030 QA

Q

I did test your temp.sensor with Sonoff ZB Dongle , but it was not perform well. 

We are trying to retest them again and hopefully , it will be working this time. Do you have any hint and/or guideline to connect them together? I do feel the Sonoff ZB Dongle with external antenna is more powerful in term of signal coverage against your ZigBee Gateway. 

We did connect Sonoff ZB Dongle with RasberriPi to linkage into our public cloud. Please advise.

By the way , for the DSS-010 temp & humidity sensor. Do you have any accuracy value of temperature and humidity you passed test?  Please declare to ensure our customer. Thank you.

#1 sensor/gateway 如何连上，应该问网关的公司，因为我们是标准的协议，等待被链接，网关是自动的一方 #2 我们也有内置天线，更多的覆盖取决于天线的设计及功率，客户需要做实际测试而不是感觉判定， #3 精度测试，我们060/070有精度测试报告，DSS-010用的哪个sensor，不同sensor不同精度

Q

1. 貴司方案是模組還是mcu base

2. 是否可以透過韌體修改與其他私有協議ZigBee網路連結

3. 貴司提供的整套方案，協議與應用層的協定有標準形式？（ZCL之類的？

4. Coordinate 可以同時與多少個end device同時通訊？

A

1.模组/SOC都可供，合适的商业模式是模组  2，只要知道其他私有协议，就可以对接  3. ZCL非标的协议我们可以定义，电钻正常没有zigbee的标准协议。  4. coordinate最多可以接40个设备

Q

How many devices can scan at the same time and is it real-time? （BLE device）

A

If you imply the BLE scanning, the gateway would scan nearby devices all the time and upload to your server as a device list in a certain time interval.
So the gateway does scan in real-time but not upload list in real time, and the maximum number of list is 400 devices for now.

Q

I have configures Aws but I cannot add the certs. I have ssh'ed the files to the gateway as Upload feature doesn't work. I then then choose the files but instead of selecting them it deletes them from the gateway and sets them back to the defaults certs

A

You could update the gateway image from the resource center to latest version and try again.

Q

客户装我们的网关及传感器时发现以下问题设备是水浸1，水浸2，温2连接网关2，湿1，湿3，温4连接网关 1.1.目前 出现大面积水浸离职，离职是昨天开始的2.设备信号时强时弱，我们在安装设备时都是有信息再固定在墙上的。过几天设备不是掉线温2，就是温3，有部份的温 4。3.通过现场查看，设备具有网络，按温湿度报警，服务器收到不网关的推送信息。

A

请检查环境是否有很厚的墙体，尽量避免墙体，设备收不到推送信息需要查看网络是否稳定，尽量采用网口进行网络连接

Q

东胜的DSGW-030 ble mesh网关能够支持客户开发自己的MQTT消息和自定义蓝牙mesh通信消息吗？

A

可以通过BLE2Mqtt MESH API.pdf接口文档进行对接，如果要自定义消息需要更改网关程序

Q

1、DSGW-030 ble mesh网关定制开发环境搭建方式，使用什么开发语言； 2、上行MQTT定制消息开发的方法，以及网关开放能力； 3、下行MESH定制指令开发的方法，以及驱动开放能力。 需要更多了解以上三点，以便评估设备选型和技术可行性，以及我们需要准备的技术人才储备。

A

开发环境参考030quick start, 如果需要通过quick start 开发网关固件，需要嵌入式linux 工程师
