Holy moly- ringing out the ICSP connector to figure out which pin went to 51, 52, etc. revealed a bad jumper. Thank you for that suggestion.
It is now detected in the Arduino IDE with FW 19.5.2, but still not in Atmosphere (I did reprogram the Mega between IDE’s).
Going back to puTTY, the output results are exactly the same as they were, where the last line says “Applying conf” and it looks like it’s not done, and it doesn’t return the firmware version.
I guess I can keep going with the adafruit/Arduino method to prove functionality, but that isn’t my real goal. If I’ve inadvertently picked the wrong WiFi board, I’m not adverse to buying the 3653, but it’s a bummer because the tutorial
didn’t draw a distinction between the two devices.
In the tutorial, when it says it’ll “scan for available devices within range”. It detects the Mega via the USB cable, right? Perhaps the paragraph before that…
I don’t know what else to try within the Atmosphere environment.
Thank you so much,
