Hey,

im trying to get some 8BItdo Controller working on the retropie. I' following the guide above, but everytime when i scan for bluetooth devices the pi freezes (or find nothing). Other devices like my mobilphone find the controller without any problems.

the following error message is displayed:

Someone can help me, what is wrong?

when i follow this guide:
https://www.reddit.com/r/RetroPie/comments/4d5hcf/how_to_setup_8bitdo_nes30_fc30_pro_controllers_on/?sort=new

at step 2, when i enter the command "sudo bluetoothctl" i can do nothing more. no chance to write the command "power on", keyboard does not react anymore

What power supply are you using ? What is the output rating? Did you try with a fresh image / different sdcard ?

I am using this Set:

So it is an 2,5 A Power supply? Could this affect the Bluetooth Controller ?
After Work i will try a new fresh Image. We will see

I consider 4.2A (steady) to be the minimum requirement to run a Pi3 with all options.

@Lyle_JP
So you think this would be the better choice for a stable running Pi?

Your psu should be fine, but it could be faulty hence worth testing another. It's possible the RPI is faulty too.

@BuZz Thanks for the help. I will Test some new psu and a fresh Image.
Hopefully it works. Will get in touch with News.
It would be annoying, if the rpi is broken..
