BeagleBone Green Wireless vs. Black Wireless & I2C

Ok. For the benefit of others, I am going to share my boneheaded mistake. For so long I have only connected the USB on the WIndows PC to the BBB through the miniUSB port that I completely forgot about the other USB connector at the other end of the board near the SD card slot. Once I put the D-Link in that slot and powered up with a DC supply to the barrel connector, i can see the USB D-Link when i run

So now, using connmanctl I successfully completed the steps you provided however I had to execute

config <id of the network>

between

services

and

connect

Now, itā€™s connected to my office network.

But when I disconnect the USB cable there isnā€™t a wifi network available that I can connect to this BB with from my Windows 10 PC. I think Iā€™m nearly there but I donā€™t know how to enable this BBB to bring up its own wireless network so I can connect to that. Thatā€™s what I really need for it to be like a Black Wireless.

I am glad to hear that you got it running now.

In my implementation I connect a number of these BBB to a network, and using my PC I have written an application that communicates to all the boards. So unfortunately, I cannot give you any meaningful advise.

Got it. Our system is a precision agriculture unit that works in the fields. So there is no wi-fi network. I need the Black to bring up a wi-fi network like the Wireless does. Iā€™ll do some more digging but at least I have a wi-fi dongle working. Worst case, weā€™ll put a standalone router on the machine to bring up the network that we need. Extra cost but a reasonable back up plan.

@WalterCEden I think that USB wireless adapter will not have the required range.

You probably need to look at a more powerful USB wireless adapter, but I think putting a standalone router on the machine will solve all your problems. It can act as a DHCP server and you can get one with the required range to connect to the client ( base ) computer.

This is my applicationā€¦

It might not, but we are only connecting to the machine with a tablet or phone for a user panel interface. It keeps it from having to be tethered. Once it is on large fields, an operator might be monitoring several of these from a distance, so weā€™ll make the change when that happens.

Diagrams are always helpful. I need to take a bit of time and make one of these too.

Thanks again, very, very much appreciated!
