Hello,
I need some advices because I did not know what to do anymore...
I have a mega 2560 coupled with a Dragino Yun Shield. I don't manage to see anymore the wifi which comes from Dragino, on my computer...
I tried to powered the 2560 with USB or with an external power supply (12V) and the probleme is still the same...
Could it possible the dragino Yun Shield dead ?!!
Any ideas ?
May thank in advance.
have you followed the documents on the Dragino-Yun-Shield-product details web page, e.g. Quick Start Guide, User Manual, etc
upload code you have used to test the device (using code tags </>)
upload a schematic of the wiring
Thank you Horace for your reply.
Yes i followed the quick start guide . The problem is at the really beggining :
Connect to Leonardo and power : ok
Simply put the Yun Shield on the top of Arduino Leonardo and Power the Leonardo via the DC
Jack. ok
Connect to Yun Shield : ok
At the first boot of Yun Shield, it will auto generate an unsecure
WiFi network call Dragino2-xxxxxx
Fot me, no wifi detected
