RK3399 与官方配件GPS的连接?
入手官网配件GPS,不知道怎么用,求帮助? 看一下wiki 配件那里 https://item.taobao.com/item.htm?id=545653310043 买后接好线,在7.1的系统里打开了GPS,折腾了好几天,还是找不到信号! 是用的官方PAI呀 但在pu ttyj里面的信号输出.接了TX这根线后代码如下:$GPGSV,3,1,12,01,51,166,,03,02,171,,07,62,314,,09,24,229,*79$GPGSV,3,2,12,11,79,195,,16,14,084,,17,07,240,,18,64,111,*7B
