Pilot网关8通道默认频率是多少?

    如上图是我终端所设置的对应网关8通道的频率,请问我刚买的Pilot网关470MHZ的,对应的8通道频率默认设置是多少?



  • 你买的是我们过阿里470MHz认证的那个Pilot网关吧?
    阿里470MHz的网关,默认配置参数都是这个(这个配置文件是阿里给的):

  • 如果你买的应该是CN470 MHz的网关,那你可以参考官方标配的配置文件:
    https://github.com/TheThingsNetwork/gateway-conf
    这里面的CN-global_conf.json。



  • @Fomi 嗯,应该是CN470的,目前设置了对应上行频率,TTN可以接收到终端的报文了。
    如下图,是不是将下行通道给关闭了?目前好像TTN发送不了数据给终端
    0_1543306259196_55.png

    若要打开下行可以吗?基于我目前的Pilot网关要如何操作?



  • 官方给的标配配置文件中,上行和下行的通道都是开的,没有关闭。
    网关在节点和Server之间只是做数据转发,TTN到终端的下行数据收不到,可能得检查终端的配置是否正确了。



  • 请问如CN470官方标配文件中,下行通道的设置是如何的?宽带、扩频因子是设置多少?



  • 我一般都是直接使用官方配置文件,也测试过上行、下行都OK。对配置文件里面的细节研究的不多,这个不敢乱回答你,sorry!
