I am using a WP7702 cell modem with my mangoh red board. I have went through all of the initial setup directions in the getting started guide. I am able to see location, pressure, light data in the airvantage cloud server. Now I am trying to use mangoh red as a gateway for raspberry pi 3 b+ to send pings to the airvantage clould server (i.e. raspberry pi pings (from its command line) message through its Ethernet port >> through Ethernet cable >> to Ethernet port on the Ethernet IoT expansion card inserted into mangoh red >> mangoh red sends ping message to the clould server. Is this possible if so, how can this be done. Please provide detailed steps to do so because my background is not programming its electrical engineering.
I did not get this error before. I’ve tried to give myself permissions to the file “export” using the chmod command however it returns no such file or directory. The echo commands below require me to access a file which is stored under “other locations” >> “computer” >> “sys” >> “class” >> “gpio” >> “export” (I am using a linux laptop with ubuntu). The export file type is unknown.
@jyijyi Okay the first echo command worked after ssh’ing into the mangoh red. Now when I type the second command echo out > /sys/class/gpio/gpio2/direction it says that this directory does not exists. (see below)
