826 +
827 +First you need to configure the certificate to the -NB node. Follow the instructions in this **[[link>>https://wiki.dragino.com/xwiki/bin/view/Dragino%20NB%20device%20connection%20to%20AWS%20platform%20instructions/#H4.1.2Configurecertificate]]** to configure the certificate.

842 +
843 +
844 +When the certificate is configured, burn the boot program, burn the working firmware, and then restart the device.
845 +
846 +Then configure the -NB node to connect to the ThingsEye platform:
