I am a beginner. When I bought my Raspberry Pi 3B a week ago, I was told that they had already applied a set-up. I didn't know what it meant and I followed a tutorial to set-up the Pi for the second time and that is when I realized that they meant they uploaded the OS onto the SD card already. Should setting up the Pi for the second time be an issue? I'd like to mention that I formatted the SD card before I myself set the Pi up.
The green LED blinks very slowly, once in 90 seconds. Does this mean anything?
Advanced IP scanner can't detect my Pi, detects every other device. Here's what I did:
i. I formatted the SD card
ii. Used Win32 disk imager to burn the Raspbian_Stretch.img file for the OS and uploaded it to the SD card's boot section.
iii. Inserted the SD card into my Pi.
iv. Connected the Pi to a power source using adapter.
What am I doing wrong? I am using a headless method and I'm trying to bring the Pi into the network wirelessly.
