I just noticed this thread. . .
First of all, Dexter Industries has gone through a major upheaval in the last year-or-so, (aside from that caused by the Covid-19 pandemic), since they have “joined forces with”, (merged with), Modular Robotics and it’s been the usual post-merger s-storm over there.
Though I am not an official part of Dexter/Modular Robotics, I have gone through so many “mergers of equals” (<== oxymoron), that I understand the post-merger struggles they have had. In as much as I, a fellow follower of the hardware/software industry can do so, I apologize for any appearance of your issue “falling through the cracks”. Had I seen this earlier, I would have immediately hopped in to try to help.
Interesting that you’re not getting any WiFi activity.
Would you be kind enough to remind me what Raspberry Pi board you’re using? If it’s a Pi-3 or Pi-4, an external dongle is not necessary.
If you have a Pi-3 or Pi-4, have you tried this without a dongle?
I am interested in what your results are - I might want to investigate this myself. (Sound bite: Evil laugh from the software/hardware testers!)
I just saw the part mentioning you’re using either a Pi-1 or a Pi-2.
“Theoretically” - it’s all one big beautiful world with the Raspberry Pi.
In practice, things have come a long way since the Pi-1 and Pi-2 have come out. Especially the complexity of the Raspbian O/S that all of Dexter/Modular-Robotics releases depend on - it’s not a 2 gig SD card containing NOOBS and every image known to man anymore. It’s a 6+gig image just for raspbian, plus any add-on’s that Dexter/M.R. add to it.
If you have not already done so, allow me to seriously recommend you upgrade to a raspberry Pi-3. (For the time being, avoid the Pi-4). They work with the Dexter 'bots, but there are issues that are still being resolved. Not “Dexter/M.R. issues” but issues with the new hardware paradigm introduced with the Pi-4.
Using a more modern Pi will give you all the benefits - a bigger, faster processor, integrated WiFi and Bluetooth, and a broader range of compatibility. Not to mention missing all the angst and bother!
Buy a heat-sink kit too and put the big heat-sink on the top of the big Broadcomm chip after swabbing it off with alcohol.
Both the Pi-3 and a heat-sink kit, (don’t get a fan!), shouldn’t set you back any further than $35-40, and is well worth the lack of aggravation.
Please let me know what’s happening.
