I am positive I ordered the chip antenna version Spark because I didn’t care about range and I didn’t want to deal with locating the antenna… BUT I seem to have been sent the u.FL version.
I tried connecting anyway with the phone / spark and wifi router all really close but the spark could not be found. Blue flashing led never changed.
I tried an antenna I pulled from an old cell phone but it made no difference.
I found links to buy one but that will take a week. Is there anything I can do now? Even just to get short range capability?
